A free review of your app.

Send the link to the app on the App Store or Google Play. I go through the first minute, where it crashes or stalls, what the reviews say and what permissions it asks for. You get a written answer within two working days.

What I look at

What usually decides it.

  • The first minute

    From download to something done: account, sign-in, and what the user sees first.

  • Crashes and errors

    Where the app stalls, crashes or shows an error, and whether you see those errors or only your users do.

  • On an older phone

    Load times, scrolling and battery on a phone that isn't the latest.

  • Ratings and reviews

    What users actually complain about on the App Store and Google Play, and what keeps coming back.

  • Permissions and privacy

    What the app asks for, when it asks, and whether the reason can be explained.

  • Updates

    How a new version reaches users, and whether anything in the stores' requirements is about to become a problem.

How it works

Three steps, no meeting.

  1. 1

    Send a link

    To the website, app, prototype, code or quote — and a sentence about what you're wondering.

  2. 2

    I go through it

    On my own, without you having to demo anything in a meeting. If I need access to something, I ask first.

  3. 3

    You get a written answer

    Within two working days: what holds up, what doesn't, and what I would do first.

Review on Google
  • Does it cost anything?

    No. The review is free, and you don't have to buy anything afterwards.

  • How quickly do I hear back?

    Within two working days of receiving the link.

  • Who does the review?

    Kenny Tran, the developer who runs Ketryon. Not a salesperson and not a tool.

  • What happens next?

    Nothing, unless you want it to. If you'd like someone to do what the answer says, the subscription is there — but the answer should be usable without it.
