Good questions.

A chatbot answers one thing you paste at a time and loses your worksheet’s structure. Skimr reads the whole sheet in one scan, solves every problem and sub-part in order, shows the work the way you’d write it, draws graphs, and puts the answers on your Lock Screen. No retyping, no cropping, no chat history to scroll through.

Your iPhone camera: snap each page, or record and move slowly over the sheet, and Skimr keeps the sharpest frame of each page. The camera starts at 0.5× (on iPhones with an Ultra Wide camera), with a lens button for 1×, and it never uses the flash.

You can also pick photos from your library, type a question, or pair a Bluetooth pen scanner or camera.

One worksheet: up to 30 pages or 100 problems. Add pages any time while the scan lasts; they join the same scan, and pages already in it are recognized and never solved twice. Skimr keeps one scan at a time, and it clears itself 4 hours after it starts.

An iPhone with iOS 18 or later. There’s no account: no sign-up, no email, no profile.

It was 98% accurate in our own practice-worksheet tests. Still, AI can be wrong, so check the work before you rely on an answer.

Each scan becomes a Live Activity on your Lock Screen and in the Dynamic Island. ‹ › pages through the problems without unlocking, wrapping around at the end, and long work continues over several pages. Tapping × twice clears the scan; the last cleared scan can be recovered with Face ID or your passcode until its 4 hours are up.

Tap the eye on the Lock Screen and the answers turn into an everyday text, from Mom unless you pick someone else: Dad, Grandma, Sister, Brother, Coach or any name you choose. Nothing about the scan shows. Tap Reply to bring the answers back.

A multiple-choice answer buzzes its letter when it comes up: A once, B twice, C three times, up to F.

4 quick buzzes before the letter mean you’re back at problem 1, a problem was skipped, or a new part of the sheet has started. It works in the app, on the Lock Screen arrows and with the Action button.

With Audio on and AirPods or Bluetooth headphones connected, the play button moves through your answers:

• Press once: next answer
• Press twice: previous answer
• Press three times: back to problem 1

It works with the screen off, so you don’t need to unlock. On AirPods (3rd generation), AirPods 4 and AirPods Pro you can slow down how fast the presses need to be in Settings → Accessibility → AirPods → Press Speed.

No. You hear each problem and its answer only in AirPods or Bluetooth headphones. Skimr never plays them from the iPhone speaker.

Yes. On iPhones with an Action button, go to Settings → Action Button → Shortcut → Skimr → Next Answer. Each press steps to the next answer.

Your scan stays on your iPhone and clears itself 4 hours after it starts. To solve it, the clearest image of each page and its text are sent to Google’s Gemini through the Skimr server, and only after you allow it. There’s no account, no ads, no analytics and no tracking, and your data is never sold.

No. Scans never touch your camera roll: pages stay inside Skimr until they clear. If you pick a photo from your library, only that photo is shared with Skimr, so Skimr doesn’t need access to your Photos.

Tap Share and send the link by AirDrop or Messages, even before you scan. Whoever opens it gets the answers, and new ones as they’re solved, always in problem order. Each link works on one phone, the first one that opens it, so tap Share again for each friend. The answers are end-to-end encrypted with a key that only lives in the link.

Yes. Your friend never sees your name, and never your pages: the images don’t save on their phone, only the answers and the work. They can view the scan, not change it or pass it on.

The last cleared scan can be recovered with Face ID or your passcode until its 4 hours are up, or deleted for good. If you’d rather not keep a way back, turn recovery off in Settings.

Yes. Turn on a PIN, and Face ID, to keep Skimr private. The PIN is stored only as a hash on your iPhone.

No. Skimr is for homework, practice and studying. Using it where devices aren’t allowed breaks school rules, so please don’t.
