Answers for capturing questions, reviewing cards, syncing data, and managing purchases.

Last updated: October 21, 2026

Getting started

  1. Create a card from a photo, an image in Photos, or a blank card.
  2. Review the recognized text and add an answer, explanation, mistake reason, folder, or tags.
  3. Save the card, then use the front and back to practice active recall.
  4. After reviewing, rate the card as Again, Hard, Good, or Easy so SlipNote can schedule the next review.

Frequently asked questions

Where are my cards and images stored?

They stay on your device by default. Pro users can optionally turn on iCloud Sync in Settings. When enabled, cards you create, their images, folders, tags, and review progress are stored in the private iCloud database associated with your Apple Account. Built-in learning packs are not uploaded.

Why did text recognition miss a formula or handwriting?

Recognition uses Apple Vision on your device. Image quality, lighting, handwriting, mathematical notation, and page layout can affect results. Always review recognized text and correct it before saving.

How do I restore a purchase?

Use the same Apple Account that made the purchase. Open SlipNote, go to Settings, and tap Restore Purchases. Restoration requires an internet connection and access to the App Store.

What is the difference between a grade pack and SlipNote Pro?

A Grade 1, Grade 2, or Grade 3 math pack is a one-time purchase that unlocks only that grade's complete training content. SlipNote Pro unlocks unlimited cards, the complete learning library, optional iCloud sync, and unlimited exports. Pro is available as a monthly or yearly auto-renewable subscription or a one-time lifetime purchase.

How do I manage or cancel a subscription?

Subscriptions are managed by Apple. Open the Settings app, tap your Apple Account, then Subscriptions. Cancellation takes effect at the end of the current paid period.

How do I back up or restore my library?

In SlipNote Settings, choose Back Up Library to save a complete copy to Files. Choose Restore from Backup to merge cards from a backup that are not already in your library. Keep backup files in a safe location.

What happens when I delete a card?

Deleted cards move to Recently Deleted and are retained for up to 30 days unless you permanently delete them sooner. Permanently deleted cards cannot be recovered from SlipNote.

Why is iCloud Sync unavailable?

Confirm that you are signed in to iCloud, iCloud Drive is enabled, network access is available, and SlipNote Pro is active. If you turn sync off, existing iCloud data remains and future changes on that device are saved locally only.

How do I request a refund?

Apple handles App Store payments and refunds. Visit reportaproblem.apple.com and sign in with the Apple Account used for the purchase.

System requirements

SlipNote supports iPhone and iPad running iOS or iPadOS 17.0 or later. On-device recognition works without sending images to a developer-operated recognition service. Purchases, restoration, and iCloud Sync require applicable Apple services and network access.
