Why it’s faster

Faster than pasting into a chatbot.

A chatbot answers one thing you paste at a time. Skimr is built around the worksheet: it reads every page at once, keeps each problem in order, and puts the answers where you can see them in a glance.

A general AI chatbot

You do the busywork

  • You retype or crop each problem one at a time
  • It loses the sheet’s numbering and sub-parts
  • Long chats drift and earlier answers get buried
  • Graphs and diagrams are hard to get right
  • The answers live in a chat you have to keep opening
Skimr

Built for the whole sheet

  • Scan every page at once: photos or a slow video sweep
  • Every problem and sub-part (1a, 1b, 2…) in the sheet’s order
  • The work, line by line, the way you’d write it for full credit
  • Graphs drawn when a problem asks for one
  • Answers on your Lock Screen, a glance away

Features

Everything a worksheet needs. Nothing it doesn’t.

Every feature at a glance, with all the details right on the card.

Lightning-fast video capture

Move slowly over the sheet: Skimr keeps the sharpest frame of every page.

  • Blurry frames are dropped. Photos work too.
  • Starts at 0.5× so a whole page fits up close (on Ultra Wide iPhones), with a lens button for 1×.
  • Never turns on the flash.

Haptics & Audio

Letters as buzzes. Answers in your AirPods.

  • Multiple choice buzzes its letter: A once, B twice, up to F. 4 quick buzzes first: back at problem 1, a skip or a new part.
  • Each problem and its answer, spoken in AirPods or Bluetooth headphones, never the speaker.
  • Headphone button: once next, twice previous, three times problem 1.

Graphs & diagrams, drawn accurately

Plotted from the math itself, with the key points labeled.

  • Drawn from the math, so they’re accurate.
  • In the app and on the Lock Screen, on a page of their own.

  • Work: Automatic, answer only, brief or every line.
  • Multiple choice: the letter, or the letter and the reason.
  • Graphs: on or off.

Pens & external cameras

They keep working with the iPhone locked.

  • Pair a Bluetooth pen scanner or a Bluetooth camera from the menu.
  • Whatever they scan is solved automatically, even while the iPhone is locked.

Never saved to Photos

Scans never touch your camera roll.

  • Pages stay inside Skimr and clear within 4 hours.
  • Photos you pick are shared with Skimr one at a time, so it needs no access to your Photos.

One-tap Clear

Clear it in the app or on the Lock Screen.

  • On the Lock Screen, tap the × twice.
  • Recover the last cleared scan with Face ID or your passcode until its 4 hours are up, or delete it for good.
  • Rather not keep a way back? Turn recovery off in Settings.

Gone in 4 hours

Every scan clears itself.

  • 4 hours after it starts: pages, answers and all.
  • One scan at a time, so nothing piles up.
  • Done sooner? One tap clears it.

No account, no ads, no tracking

Open it and scan. Your data is never sold.

  • No sign-up, no email, no profile.
  • No ads, analytics or tracking.
  • Pages go to the AI (Google Gemini, through the Skimr server) only to be solved, and only after you allow it.
