Help with the Synapse apps

Frequently asked questions

How do I buy the app, and does it work on all my devices?

Each Synapse app is a free download. After the sample session, a single one-time purchase through Apple unlocks everything. The purchase belongs to your Apple Account, so it works on every iPhone and iPad signed in to the same account. There is no subscription.

I bought it already, but the app is locked again.

Tap Restore Purchases, which appears on the unlock screen and in Settings inside the app. This asks Apple to confirm your purchase and unlocks the app without charging you. Make sure the device is signed in to the Apple Account that made the purchase.

How do refunds work?

Refunds are handled by Apple, not by us. Request one at reportaproblem.apple.com. If Apple grants the refund, the app locks again on your devices.

Where does my study data live?

Only on your device. Study history, settings and progress are not synced to us or to any server, and we cannot see them. A device backup through iCloud or your computer includes them, so moving to a new phone means restoring that backup. Deleting the app deletes the data.

Does it work offline?

Yes. Everything works without a connection except two things: the purchase and restore themselves, which Apple performs, and opening a citation, which loads the source's web page.

How current is the content, and how do I report an error?

Content is written against current guidelines and reviewed on a schedule; the app's About screen shows the date of the last review, and each card's citations open the source. If you find an error, email support@synapseboardreview.com with the card's topic and the first few words of the card, and we will check it against the source and correct it in the next content update.

What is the sample session?

A short, one-time walk through a few cards and two course pages before the purchase screen appears. Nothing from the sample session is saved. It runs once per installation.

Which devices are supported?

iPhone and iPad running iOS 26 or later. There is no Android, web or desktop version.
