Support
support@o2apps.store. Say which iPhone and iOS version you have and what you were doing; a screen recording helps more than a screenshot.
Restore a purchase
Open the app, go to Settings and tap Restore Purchases. You must be signed in with the same Apple Account you bought Pro with. If it still does not unlock, email us with the App Store receipt.
The floating window does not appear
Check Settings → General → Picture in Picture on your iPhone and make sure "Start PiP Automatically" is on. Then start the prompter and tap the PiP button before you switch to your camera app.
Voice scroll does not follow me
The app needs microphone and speech recognition permission (Settings → Teleprompter PIP). Voice scroll works best with clear speech close to the script; it only moves forward, so if you skip ahead, tap to catch up.
Something else
Bug reports and feature requests go to the same email. You can also leave a review on the App Store page; we read those too.
