Appray for iPhone & iPad
Build.
Kill.
Prove.
Stop praying your app will succeed. Appray helps founders, indie makers and product designers validate product ideas with Jobs To Be Done (JTBD) — before writing a single line of code.

How it works
1
Answer, don't stare at a blank page
Guided prompts walk you through the job your product is hired to do, the pressure behind it and the outcome people actually want.
2
Every feature defends itself
In Feature Court each feature is scored against visible rules — does it support the main job, does it create the first value moment.
3
A clear report, not just hope
You get a verdict for every feature — Build, Later, Kill or Prove — and a shortlist of what to test first.
Built for privacy
No AI. No cloud. No account. Your ideas and answers stay on your device — they are never sent to AI models or external servers.
No accountNothing to sign up for.
No AI APIAnswers never leave for an AI.
No trackingNone in the app; this site is static, no analytics.
On deviceStored locally, not on a server.
Languages
Appray follows your iPhone language and speaks English, German and Russian.
One honest limit
Appray does not prove product-market fit and does not guarantee that an idea will work. It turns your assumptions into clearer decisions and a shortlist of next tests.
