What is TestFi?
TestFi is a crowdtesting platform that connects app developers with verified human testers. Developers post a campaign with their app link, hand-pick testers from a pool of 2,000+ verified participants, and receive screen-recorded video feedback within 24 hours. Every session is automatically evaluated by a 6-layer AI scoring engine that surfaces usability issues and ranks them by severity. Written feedback costs $1.99 per tester and video sessions $3.99 per tester — pay per tester with no subscriptions or minimum commitments. TestFi supports iOS (TestFlight), Android (APK), and web applications at any stage from MVP to production.

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."
