Built for developers.
Paid for by results.

UserTesting starts at $30K/year. Maze starts at $1,200/year. Both require contracts. Neither was built for someone with a TestFlight link and a launch date next week.

Can Dizdar built TestFi in 2024 after dealing with this for years while building his own apps. The options were either unaffordable or useless. Friends said it looked fine. Beta users sent nothing, or one line. Professional tools were out of reach for anyone not in a well-funded company.

So he built what he actually wanted.

Post your app link, TestFlight, APK, or web URL. Write test scenarios. Pick a tester count. Applicants from the verified pool apply within hours. You review their profiles and choose who fits. They record their session with voice narration and file a written report.

Every submission runs through a 6-layer AI scoring system: task completion, navigation depth, session time, narration quality, attention zones, report specificity. You get a ranked list of what to fix. Not a pile of recordings to sort through yourself.

$1.99 per written session. $3.99 per video session. 10–50x cheaper than the tools it replaces.

People sign up to test apps and earn money for each session they complete. The tester community is growing every week.

Written feedback pays $1.00. Screen recordings pay $2.50. Most sessions run 10–20 minutes. If you earn money online through gig or task work, app testing is a clean option, the requirements are written out before you start, pay is fixed, and the feedback you give ends up in something someone is about to put on the App Store. Not star ratings. Actual testing.

Testers build a reputation score over time. High scorers get first access to new campaigns.

Most platforms hand developers a random panel and step aside. TestFi lets you see each applicant's device, OS version, and testing history before you accept them. That matters when you need a specific Android version tested, or when you've been burned by low-effort submissions before.

Developers fund a campaign before it goes live. Testers are paid automatically once their submission clears quality checks. Escrow on both sides.

The workflow is straightforward. A developer creates a campaign by sharing their app link — TestFlight for iOS, APK for Android, or a web URL, writes the test scenarios they want covered, and sets a tester count. The campaign goes live immediately.

Testers from the verified pool apply. The developer reviews each applicant's profile, devices, and past quality scores, then hand-picks who to accept. Accepted testers record their screen with voice narration while working through the scenarios, then submit a written feedback report.

Before the developer sees anything, every session runs through the AI scoring engine, six dimensions of analysis that catch low-effort submissions and surface the most actionable feedback. The developer gets a ranked list of what to fix, not a pile of recordings to sort through.
