Your notes become questions. Your scrolling becomes revision.

Toll is an iPhone app for anyone working towards something: an exam, an interview, a new language. Before an app you've put a toll on opens, you answer 3 quick questions from your own notes, so your scrolling becomes revision.

You pick something to learn, from Toll's packs or your own notes, and put a toll on the apps that eat your time. Before a tolled app opens, answer 3 quick questions; get them right and all your tolled apps open for 15 minutes, or any time you choose from 1 to 60. Spaced repetition picks the questions, so each one is revision you were due anyway.

Anything you're working towards: an exam or test, a job interview, a language, or learning for fun. Set a date and Toll paces your revision to it, or leave it open.

From your own notes: add them and Toll writes questions from them with AI. You check every question it writes before it reaches a toll, and cards you already have come in from Anki or a CSV file. Questions are multiple choice or typed, and two packs, World flags and Capitals, let you try Toll before you add yours.

Pasted text, a link, PDFs and lecture slides, photos or scans of printed or handwritten notes, Anki (a plain-text export) and CSV. Word and PowerPoint: save them as PDF for now.

On a computer: Anki → File → Export → Notes in Plain Text (.txt), untick Include HTML, save it to iCloud Drive, then choose it in Toll. .apkg files from AnkiMobile are coming soon.

Toll reads the text on your iPhone; photos and PDFs never leave it. The text goes to Toll's server and to Anthropic, the company behind Claude, to write questions, and it's never used to train AI; Toll keeps the questions and the line each one came from, not the rest of your notes. Don't include patient details or anything that identifies a person.

Any apps you tick in Apple's Screen Time list, including whole categories like Social. We suggest leaving messaging, maps and banking alone, so they're always one tap away.

You'll always get in. You have 2 free passes a day that skip the questions, and if you get 3 answers wrong in a row, Toll shows you the answers and lets you in after 60 seconds. A single wrong answer just shows you the right one, and you carry on until you've got 3 right.

Miles are how far you've come: one for every card you study or get right. Coins are what you spend: a coin pass opens your apps without questions. They can't be bought.

No: Apple's Screen Time keeps your app choices on your phone and gives Toll anonymous tokens instead of app names, so Toll never sees which apps you use. Your library is backed up to Toll's server, and the anonymous usage events we collect never include your notes. Your notes leave your iPhone only to have questions written, and Toll keeps only the questions and the line each one came from.

An iPhone on iOS 26.5 or later and Apple's free TestFlight app. To check your version, open Settings → General → About.

Toll is free during the beta. You install it through Apple's free TestFlight app, and there's nothing to pay.

Opal and one sec are blockers; Toll is a study app with a blocker built in. Opal blocks apps on a schedule, and one sec adds a breathing pause before an app opens. Toll's pause is 3 questions from your own notes, so the friction turns into revision.

Anki and Quizlet are flashcard apps you open to study; Toll brings your revision to the apps you already open. Plenty of people pair a flashcard app with a separate blocker, and in Toll that pairing is the product. You can bring Anki cards over with its plain-text export, or import any cards saved as a CSV file.

As soon as your invite arrives: we're emailing TestFlight invites to the waitlist in small batches. Toll isn't on the App Store yet, so joining the waitlist is the way in.
