Frequently Asked Questions
Why do I need Screen Time permission?
On iOS, Anstogo uses Apple Screen Time related APIs to apply restrictions to apps, categories, or websites you select.
How do I unlock an app?
Open the unlock challenge from Anstogo or from the lock screen flow, answer the required questions, and temporary access will be granted.
Can I choose difficulty?
Yes. You can select a difficulty band or choose random difficulty in Settings.
What is Independent Lock?
Independent Lock unlocks only the specific app you challenged for. Other locked apps remain restricted.
What is Heteronomy Mode?
When enabled, users cannot manually unlock apps from the locked app list, helping reduce impulsive bypassing.
Why are Pro features unavailable?
Reopen Anstogo, make sure you are signed in with the same account, and check your subscription status in Settings.
