Frequently asked

Does it sync with the web app?

Not in v1. Your iOS progress lives on your device only. The web app at exact-values.com stays free and stat-tracked separately with sign-in.

Why use the app if the web app is free?

The iOS app gives you a focused, offline practice loop with native keyboard, haptics, and daily reminders — things the web can't do as cleanly. Same content, sharper habit tool.

Will there be subscriptions or ads?

No. Free to download, no subscriptions, no ads. Future updates are included.

Does it read the answers out loud?

Yes. After each question the correct value is spoken aloud using on-device text-to-speech — no network needed. You can turn it off in Settings or right from the quiz screen.

Which devices does it support?

iPhone and iPad running iOS 17 or later.

What data does it collect?

None. The app has no analytics, no network calls, and no account system. Your stats stay on your device.
