Pro

$9.99
Pay once. Own everything Pro ever becomes.
  • Everything in Free, plus:
  • The full listening model. A 1.3 GB neural ear, downloaded to your phone. The bundled tuner is the scout; this is the specialist. It holds its lock in wind, distance, and rough recordings where the scout says not sure.
  • Every future Pro ability, included. Buy once and the upgrades keep arriving. No second purchase, ever.
In the workshop

Two abilities are on the bench now and land in Pro at no extra cost:

  • Cloud photo analysis: show it the leak
  • Cloud sound analysis for the hardest cases

When they arrive, a photo or clip goes to the cloud only when you press the button. Everything else stays on the phone, same as always.

Honest questions

Why is Free actually free?The model runs on your phone, not our servers. It costs us nothing when you ask a question, so we charge you nothing.
Will Free stay free?Yes. Nothing that is free today goes behind a paywall tomorrow. No ads either.
Why is Pro paid?Pro is what keeps Free free. Ten dollars once funds the bigger listening model today and the cloud abilities being built now, and your seat covers all of it for good.
What does Pro get me today?The full size listening model on your phone. The features marked in the workshop arrive as free Pro updates when they are ready, not as new purchases.
Is it a subscription?No. You pay one time through the App Store and it is yours.
Can it replace my mechanic?No, and it will tell you so. It helps you understand the problem, judge urgency, and walk into the shop informed.
