Nga 64,858 vlerësimet, klientët vlerësojnë Mobile App Testers 4.9 nga 5 yje.I need fresh eyes on our live-streaming app to see how well it serves people who rely on accessible design. The priority is pure usability testing, zeroing in on accessibility on both laptops and smartphones—no performance metrics or deep functional audits this round. Here is what I am looking for: • A structured accessibility-focused usability test on the current production build (web and mobile). • A concise report outlining issues, their impact on real-world use, and quick-win improvement suggestions. • Screen recordings or annotated screenshots that clearly demonstrate each problem you uncover. You are free to use any assistive tech you normally rely on (screen readers, magnifiers, voice control, etc.), but please note which tools you used so I can reproduce...
We are looking for an experienced mobile app tester / QA specialist to test our existing mobile application and help complete the remaining work. The app is already development by a third-party development company, but several features, bugs, and UI/UX issues are still pending. We need someone who can thoroughly test the app, identify problems, and coordinate with the development team to ensure fixes are implemented properly. #Responsibilities • Test the mobile app thoroughly on different devices • Identify **functional bugs, crashes, and performance issues** • Review the app for **UI/UX problems and inconsistencies** • Prepare clear **bug reports with screenshots/videos and reproduction steps** • Coordinate with the third-party development team to ensure bugs a...
I will supply 3–5 utility-style entertainment apps that feature an AI chatbot. Your mission is to play with each one until every possible advert presents itself, then document exactly what caused it. Here is what I expect: • Run the app on a real device (Android or iOS is fine). • Whenever an ad appears—banner, interstitial or rewarded—start a quick screen recording, grab a screenshot and write down the user action that fired the placement (e.g., “changed character → interstitial”, “opened settings → banner”). Package all recordings, screenshots and a concise spreadsheet or doc that maps: app → ad type → time-stamp → trigger → ad type → file name of evidence. If something looks off, add a...
Within my AppPresser-based mobile app I already expose BuddyPress settings, and the account-deletion button is visible to logged-in users. When it is tapped, however, the request consistently times out instead of completing the BuddyPress “Delete Account” routine on the connected WordPress site. Here is the current situation • AppPresser + BuddyPress (latest stable releases) power both the app and the site. • The button calls the built-in BuddyPress delete URL, but the process never finishes; the app shows a timeout page. • I haven’t yet pulled detailed server or device logs, so the exact error stack is still unknown. What I need from you 1. Diagnose why the request from the app is stalling—whether that is a REST/nonce issue, a CORS or SSL...

I have a live SwiftUI-based social app that already ships chat, video feeds, stories, live scenes, an in-app currency (stars) and subscription flow. The code follows MVVM, talks to a set of REST back-ends and is in the store today. What I need now is an experienced iOS engineer who can drop into the existing project, diagnose issues quickly and raise the overall quality bar. The immediate focus is three-fold: • First, do a thorough walkthrough of the current codebase so you understand our MVVM layers, networking helpers and IAP logic. • Next, remove bugs that are spiking our crash reports and tighten up general stability. • Finally, tune performance in the chat and media areas, then layer in a handful of small feature requests we already have queued for those modules....
I’m building the first version of a mobile app both iOS and Andriod entirely in FlutterFlow, backed by Firebase, and I’d like an expert who can set up a solid, no-code foundation that we can keep expanding. Current scope • User onboarding with Firebase phone-number authentication only (no email or social logins for now). • In-app purchase flow powered by UPI. The app must support both subscription plans and one-time premium unlocks, all handled inside FlutterFlow and recorded in Cloud Firestore/Realtime DB for entitlement checks. • Clean data architecture in Firebase so future modules can be added without painful refactors. Deliverables 1. A ready-to-publish FlutterFlow project with UPI payment widgets and verified test purchases for subscriptions an...
I want to swap the live camera feed on an older, jail-broken device (iOS 13–14 running Dopamine or a similar rootless setup) with a predefined asset so I can study how iOS handles media input. The tweak should let me point the system camera APIs to either: • a single static image (JPEG or PNG) • a looping video file (MP4) Ideally I can drop the asset into a folder or set its path in a simple prefs bundle, then toggle between “live”, “image”, and “video” without rebooting. No need for App Store integration, entitlement trickery, or third-party service hooks—this stays strictly on-device for personal, non-commercial testing. Deliverable • Rootless .deb that installs cleanly on Dopamine • Preference pane (or command-li...
I run an online radio station and already have a fully-functional Android app on Google Play. I now need an iOS counterpart that mirrors that Android experience pixel-for-pixel, with the single, essential feature of uninterrupted live streaming of our station. No user sign-up, email, or social logins are required—listeners should be able to open the app and press play instantly. You will receive: • The Android APK, source screenshots, colour codes, and all artwork (logo, splash, icons). • The streaming URL we currently broadcast from (Icecast/Shoutcast). Your job is to: 1. Recreate the existing UI and navigation in Swift (or SwiftUI if you prefer) so it feels identical on iPhone and iPad. 2. Implement the live audio stream with robust handling for background pl...
I need a thorough, end-to-end QA sweep across both the Android app and the web version of “Umrah Chalo,” my Umrah travel-planning platform. Your mission is to uncover every functional bug and usability snag before our next release and present them in a clear, reproducible format. Scope of the test • Platforms: Android (phone and tablet) and all major web browsers. • Critical user flows: – Account creation and secure login (email, social, OTP). – Search for packages, hotels and transport, with filters and sorting. – Full booking and payment journey right up to the confirmation screen, including failed-payment handling. What you’ll deliver 1. A consolidated defect log (spreadsheet or tracker) describing steps to reproduce, e...

I have a Flutter app running on both Android and iOS and I need two things tidied up before I push the next release to the stores. First, the push-notification redirect is broken. A user can receive the notification, but tapping it no longer takes them to the intended screen. I need that deep-link behaviour restored and tested in cold-start, background-resume, and foreground states on both platforms. Second, I’d like a small facelift inside the app: the menu layout needs re-ordering and spacing tweaks. Colours, icons, and the rest of the UI stay as they are; this is purely a navigation-drawer update. The full Flutter source code, keystore, provisioning profile, and current store listings are ready for you. Once fixes are complete, I’ll need new signed builds uploaded through...

I’m steering the build-out of a gym-management and fitness-tracking SaaS that covers membership management plus personal-training and workout-tracking modules. The product will roll out simultaneously on Web, iOS and Android, and must serve three clear roles—Admin, Trainer and Member—right from day one. Your primary focus is to turn high-level feature ideas into crystal-clear user stories with acceptance criteria, keep them moving through design and development, and then verify the finished work. Day to day you’ll sit with me to refine requirements, document every task for the developers, and stay on top of the board until each story meets its definition of done. Once code is ready, you’ll hit the APIs in Postman, run functional UI passes on all platforms, pr...
I’m looking to roll out a dedicated Android app that lets my site engineers capture everything that happens on a construction project—while they are still on-site. Core workflow The app opens to a simple dashboard where the crew can: • File a structured daily report (labour, materials, weather, notes). • Attach and annotate unlimited photos straight from the phone camera. • Create, assign, and update tasks so I can track execution in real time. What matters most to me is speed and offline reliability: if there’s no signal, data should sync automatically once the device reconnects. A clean UI that field staff can learn in minutes is critical; think big buttons, clear status indicators, and minimal typing. Tech expectations Android is manda...
A formal WhatsApp invitation is required for an upcoming corporate event. The copy must display flawlessly on every smartphone—Android, iOS, and even WhatsApp Web—without broken line breaks, unreadable fonts, or odd character encoding. Content & tone • Formal, polished wording that fits a business audience. • Mandatory placeholders for the event date & time and the venue address. • No dress-code mention. Functional needs • Message length kept compact so the entire text is visible in the chat preview. • Compatible with the latest stable releases of WhatsApp on Android 14 and iOS 17 (I will test on both). • UTF-8 safe characters only; smart quotes, emojis, and rich-text styling (bold/italics) are fine if they render consistently...
I’m building a mobile experience that lets users strengthen both their trading discipline and their body in one place. The app has to land on iOS and Android from day one, share a single code-base where possible, and feel truly native on each platform. Core flow • Each morning the user receives a concise technical and fundamental market brief, followed by a short workout or recovery routine matched to that day’s intensity. • They set parallel targets—profit percentage or dollar gain on the trading side, reps or distance on the fitness side—and see them plotted together. • Wearable fitness trackers feed heart-rate and calorie data directly into the app, while connected brokerage accounts stream live positions and P&L. • End-of-week th...
The goal is to complete a thorough round of manual QA on my production-ready web application before the next release. All core journeys—login, form submissions, multi-step user workflows, and the main dashboard—must be verified end-to-end. Testing should run on Google Chrome, Mozilla Firefox, and Safari across Windows and macOS so we can be confident of cross-platform consistency. I also need coverage for every permission level: Admin, Regular user, and Guest. You will exercise standard functional and regression scenarios as well as edge cases to surface UI defects, logic errors, and stability issues. Please explore negative paths in addition to the happy paths, keeping an eye on usability and performance hiccups that might slip past automated checks. Deliverables: • A ...

Job Title: Senior Full-Stack App Developer for Debugging, UX Fixes, and Stability Improvements Job Description: I’m looking for an experienced full-stack developer to review and refine an existing mobile/web application that is already built and functional but needs polishing and technical corrections. The goal is to identify and resolve smaller issues that affect user experience, logic flow, and overall stability. This is not a project from scratch. The application is operational, but it requires a developer who can carefully audit the system, locate inconsistencies, and implement clean fixes. Responsibilities include: Reviewing existing frontend and backend logic Fixing UI/UX inconsistencies and interaction bugs Ensuring user actions trigger the correct outcomes across the pl...
I need native smartphone users currently located in Belgium, Taiwan, Colombia, Argentina, France, Mexico, Chile, or Spain to run a round of functional tests on our dual-service mobile application. The job is straightforward: First, install the latest build on both iOS and Android devices you own. Create a new account so I can verify that user registration works smoothly in each market. Next, move on to the two core journeys—booking a ride and ordering food. Complete each flow from start to finish, including payment (we provide promo codes so you will not be out of pocket) and cancellation where relevant. While testing, note every screen, button, message, and edge case that behaves unexpectedly or feels confusing, capture screen recordings or screenshots, and collect basic device lo...
My mobile application for the general public is already coded for both iOS and Android, but it still needs a final push before launch. I’m looking for someone who can take full ownership of the finishing phase: hunt down and fix every bug, wire up eight payment gateways alongside two payout methods, connect the existing P2P + SFU server, move the backend to its new hosting environment, document the whole process, and finally publish stable builds to the App Store and Google Play. Deliverables • End-to-end functional and regression testing with issue resolution • Seamless integration of 8 payment gateways and 2 payout flows already selected in the codebase • Configuration of P2P and SFU services inside the app so real-time features perform smoothly under load &...
I’m ready to turn a fresh social-networking idea into a polished iOS app focused squarely on entertainment. The first release needs just one mission-critical feature: a real-time messaging system that feels as fluid as Apple’s own Messages. Everything else—profiles, content sharing, and any flashy extras—can wait for later iterations, so your attention can stay on building a rock-solid chat experience. Here’s what I have in mind: • Swift or SwiftUI codebase that compiles cleanly in the latest Xcode • Secure user authentication (Apple ID preferred, but I’m open to Firebase/Auth0 if you have a strong argument) • 1-to-1 and group messaging with push notifications that actually land • A lightweight, modern interface that looks at ...

I need an Xposed module that tightens security by controlling app permissions automatically, based on user-defined conditions rather than simple allow/deny prompts. The idea is to intercept any permission request at runtime, check it against a rule set (time, network, app state, or other triggers we agree on), and then grant, deny, or prompt accordingly— all without touching the original ROM. Scope – Develop the full module in Java/Kotlin for the current Xposed/EdXposed framework. – Build a compact UI for adding, editing, and importing rule profiles so users can craft conditions such as “Block camera when screen is casting” or “Allow location only on trusted Wi-Fi.” – Ensure rules apply instantly after creation and survive reboots. &nd...
You MUST be in the USA for this because these are US telco/banking etc. apps. There are 4 apps/websites you already have. I’d like you to install each one, work through the main user flows, and tell me where the experience shines and where it falls short. Your focus should stay on this area: • Functional testing – does every feature behave as expected, and are there any crashes, glitches, or confusing steps? I’m especially interested in just yes/no on the functions and comments for these 26 quick points of observation. If you have an Android/iOS phone and can dedicate a few focused hours to real-world use, I’d love to hear your insights.
I'm looking for immediate support to resolve the "Error 3 - Code Already Used" I receive when attempting to upload an AAB package to the Google Play Console. Current Situation • The app compiles and launches successfully locally. • When uploading the AAB release, the console blocks the publication, reporting Error 3 with the message "Code Already Used." What I Need 1. Quick analysis of the Gradle project to identify the cause (versionCode/versionName, signature, automatic increments, any pending artifacts). 2. Correction of the offending parameters and generation of a new signed AAB. 3. Successful upload of the release to the Google Play Console with my confirmation. I will accept the job when: • The corrected AAB is accepted without errors by the...
