Your agent guesses at mobile, and people can tell. We hand it the rules. In private preview.

Track how you sleep.

Three nights in and it starts spotting your patterns.

Get started

What the guides cover.

  • Signing people in

    Apple, Google or email, and a session that survives closing the app.

  • Gestures that feel right

    Swipe, drag and press, with the timing people expect from a phone.

  • Getting paid

    Subscriptions and in-app purchases, on both stores, without losing sales.

  • Push notifications

    Permission at the right moment, then messages people do not mute.

  • Photos and the camera

    Capture, pick and upload, and the permission prompts that go with them.

  • Working offline

    Keep the app usable on a bad train, then sync when the signal returns.

Ask, read, build.

  1. 1

    Ask in plain words

    Say what you want, like sign-in with Apple, or a feed that keeps its place when you come back.

  2. 2

    The right guide answers

    Back comes the approach, the parts people get wrong, and code that works on both phones.

  3. 3

    It builds on that

    Your agent follows a pattern that already shipped, instead of guessing and hoping.

Give your agent a mobile education.
