Userbrain Alternative for Indie iOS Developers
Userbrain is a high-quality service for unmoderated usability testing. You write tasks, and a tester from its panel does them and thinks aloud. You get a recording of the tester's screen and voice. If you have the budget, it is a good tool.
This page is for solo developers and small teams with an iOS app on the App Store and very little money for testing. It compares Userbrain with Raizy, a free feedback exchange where indie iOS developers test each other's apps.
We say clearly when each tool is the better choice. All Userbrain details are as of October 2026. They come from its pricing page and help center.

When Userbrain is the better choice
Choose Userbrain if one of these points is important to you.
You need testers from your target audience
Is your app for nurses, retirees or parents in Germany? Then a panel with demographic filters and screening questions gets you much closer to your real users than any developer exchange.
Raizy testers are iOS developers. They may not be the people your app is for.
You want to hear people think
Thinking aloud is the classic usability method. Jakob Nielsen calls it the #1 usability tool. It shows you what users believe about your interface while they use it.
A tester who says "I thought this button saves the draft" gives you information that a silent recording cannot give. Raizy recordings have no audio.
Your app is not live yet, or not only on iOS
Userbrain can test a native app from its App Store or Google Play link. Its help center explains how to test a TestFlight build with a public link. Userbrain can also test websites and Figma prototypes.
Raizy works only with iOS apps that are already on the App Store.
You work in a team
Userbrain plans include these team tools:
- Team members.
- Guests who can watch sessions and comment.
- Timestamped notes.
- Clips.
- Transcripts.
- AI summaries.
- Shareable test reports.
If several people must watch, comment on and share sessions, Userbrain is built for that.
You can try it first. The free trial lasts 30 days and includes 2 panel testers. You do not need a credit card.
When Raizy fits better
Your testing budget is close to zero
By our own calculation, Starter costs about $16 per panel tester ($49 divided by 3). Unused testers expire at the end of each monthly cycle. That price is fair for a funded product, but for a side project the cost grows fast.
Raizy costs no money. You pay with your time instead.
When a moderator approves a feedback session that you give, you earn 1 credit. One credit buys a feedback session on your app.
You want notes from people who build apps
Your Raizy testers are indie iOS developers. They do not represent your target audience, but they know how iOS apps usually behave. That knowledge helps when a flow does not follow platform conventions, or when a screen hides its main action.
Use up to 500 characters of instructions to tell them what to check.
Your app is live and you want real installs
Testers install your app from the App Store on their own iPhones. They see the same download and first launch as a real user. You do not send builds or manage tester groups.
You want a check on effort
A moderator checks every recording or screenshot and the notes before Raizy moves any credit. The moderator rejects low-effort feedback. You read approved feedback sessions under My Requests.
The 1 to 5 impression stays private. It is never public, and Raizy never posts it to the App Store. No task asks for a rating or review.
What you give up with Raizy: audio, targeting and pre-release builds. If you need them or the team tools above, use Userbrain or a similar paid service.
How to use both
The two tools answer different questions. On a small budget, they work well together.
- Start with Raizy after each release. Request a few feedback sessions. They find broken flows, unclear screens and onboarding problems. Almost any tester finds these problems, developer or not.
- Fix what they find. Do not pay a tester from your target audience to find the same bug.
- Spend Userbrain testers on audience questions. Use screening questions to reach the people your app is for. Then ask what only they can answer. Do they understand what the app does from the first screen? Would they use it?
- Keep rounds small. Jakob Nielsen recommends many small tests of about 5 users instead of one big study. Our guide on how many testers you need shows how to plan the rounds.
