How it works

Three steps. One scan.

Point your camera at the worksheet and Skimr does the rest: it finds every problem, solves each one with the work, and lines them all up in order on your Lock Screen.

The steps

Three steps, then it cleans up after itself.

There’s nothing to set up and nothing to sort. You scan; Skimr handles the rest.

  1. Step 1: Scan

    Snap each page, or record a slow video sweep over the sheet. Pages can go in any order. Bluetooth pens and cameras work too, or just type a question.

  2. Step 2: Solve

    Every problem and sub-part (1a, 1b, 2…) is solved in the sheet’s order, with the work line by line and a graph wherever one is needed.

  3. Step 3: Review

    The answers wait on your Lock Screen. Page through them, feel multiple-choice letters as buzzes, hear them in your AirPods, or step through with the Action button.

  4. Done

    The scan clears itself 4 hours after it starts. Finished early? One tap clears it.

Why it’s simple

Nothing to learn, nothing to manage.

  • No account

    Open the app and scan. No sign-up, no email, no password.

  • Any order

    Shoot the pages however they come. Skimr lines the problems up by their numbers.

  • Never twice

    Add pages any time. A page that’s already in the scan is recognized and never solved twice.

  • Nothing to tidy

    One scan at a time, and it clears itself. There’s no library of old sheets to manage.

  • Nothing in Photos

    Scans never touch your camera roll. Pages stay inside Skimr until they clear.

  • No unlocking

    Answers wait on the Lock Screen, and pens and cameras keep working with the iPhone locked.
