What is TestFi?
TestFi is a crowdtesting marketplace that connects app developers with verified human testers for real-device usability testing. Developers post a campaign with a TestFlight link, APK file, or web URL, define a test scenario, and hand-pick testers from a pool of 2,000+ verified participants across 12+ countries. Testers complete the scenario on their own devices, recording their screen and narrating observations in real time. Within 24 hours, developers receive video recordings alongside an AI-generated report that scores each session across six quality dimensions: task completion, navigation depth, session duration, narration clarity, attention zones, and report specificity. Pricing is pay-per-result: $1.99 per tester for written feedback, $3.99 per tester for full screen recordings. There are no subscriptions, no minimum campaign sizes, and no SDK to install. TestFi is built for indie developers, bootstrapped startups, and small product teams.

What they found
"Send Feedback" button opens a 404 page
Word definitions work in Journey but not Daily Verse, same app, different behavior
Orange book icon is tappable but does nothing
Some words don't show definitions when held, a core mechanic
What testers said
"The app icon looks like a bible. Maybe try a scroll or papiro, something that signals poetry."
"Does solving a level feel satisfying? Yes, the journey character motivates someone to continue and learn more about poetry."

FAQ
Common questions
What is crowdtesting?
Crowdtesting is a software testing method where real users, rather than an internal QA team, test an application and report usability issues, bugs, and UX friction. TestFi is a crowdtesting platform that connects indie developers and startups with a pool of verified testers worldwide.
Is TestFi a TestFlight alternative?
TestFi works alongside TestFlight for iOS apps and supports Android APKs and web apps directly. Unlike TestFlight, which distributes builds without structured feedback, TestFi adds screen recordings, voice narration, written feedback, and AI-scored UX analysis to every session, giving developers actionable results, not just install numbers.
How is TestFi different from UserTesting or Maze?
UserTesting starts at $49 per session and requires a subscription. Maze charges a flat monthly fee. TestFi charges $1.99–$3.99 per tester with no subscription or minimum commitment. TestFi also lets developers hand-pick individual testers from the applicant pool, neither UserTesting nor Maze offer this.
What types of apps can be tested?
TestFi supports iOS apps distributed via TestFlight, Android apps via APK links, and any web application. No SDK installation or code changes are required.
How long does a campaign take to fill?
Most campaigns fill within 24–48 hours. Tester sessions are typically completed and submitted within the same window, so developers usually have results the same day.
Who reviews the feedback?
Every session is automatically scored by TestFi's AI before it reaches the developer. The AI evaluates specificity, reproducibility, and UX impact, filtering out low-effort submissions so developers only see actionable feedback.
Do I need to install anything or change my code?
No. TestFi works with your existing app link, TestFlight URL, APK download link, or web URL. There is no SDK, no tracking code, and no changes required to your app.
