Frequently Asked Questions
My photos are not saving.
Check Muum’s add-only Photos permission in iPhone Settings and make sure your device has enough free storage.
My video has no sound.
Check video audio recording under the detailed menu → Settings, and Muum’s microphone permission in iPhone Settings. Without microphone permission, videos are recorded without audio.
Why is photo resolution different from the built-in camera?
Silent photos are saved from video frames. Resolution varies by capture mode and supported device formats, and may differ from the built-in camera.
A deleted photo still appears as my latest capture.
Muum keeps one local copy of your latest capture. It is replaced when your next capture is saved successfully. Deleting the app removes its internal copy but leaves photos and videos already saved to Photos.
Are there capture limits in the free version?
There are no photo or video capture limits. The free version displays banner ads.
How do I remove ads?
Go to the detailed menu → Settings → Premium to make a one-time ad removal purchase. Check the purchase screen for the price in your local currency.
I purchased ad removal but still see ads.
Sign in to the App Store with the Apple account used for your purchase, then choose the detailed menu → Settings → Premium → Restore Purchases. Pending purchases take effect after approval. Ads may return after a refund or revocation.
The light does not work with the front camera.
