A little help along the way

Is the app free?

The app and starter characters are free, with no login or photo upload required. Custom characters and refills are optional, one-time in-app purchases.

What can I upload?

PNG, JPEG or HEIC, up to 8 MB and 64 megapixels. Large photos are resized. Use a clear single subject that you have rights to use: yourself, a consenting adult, a pet or your own artwork. Minors, celebrities, unauthorized and inappropriate content are not allowed. Passing the photo check does not guarantee every generation.

Can a concept change clothes or art style?

Concepts are optional and describe mood, expression or action. Clothing, appearance and art-style changes are not supported. You can use the default actions. AI results vary.

What if I close the app during generation?

Accepted server jobs may continue. Reconnect, sign in with the same Apple account and resume setup. Use the results-and-attempts recheck action before starting again. A connection error does not establish that generation failed or an attempt was returned.

Does selecting a result make it final?

Clicking a result saves a temporary selection. You can change it until you finish setup. Finishing locks the image and schedules the original photo and unselected results for deletion. Supported settings such as name, dialogue, size and speed remain editable.

Can I resume unfinished setup later?

Yes, but temporary assets are not kept forever. Draft assets are normally cleaned up after 30 days since their last change. Cross-device recovery does not guarantee every unfinished input is copied.

I paid, but my character or attempts are missing.

Check your connection and Apple login, then reopen with the same account to allow purchase delivery and recovery. Avoid buying again; contact support if the issue persists.

Can I use another Mac?

Within the same service environment, sign in with the same Apple account to recover saved characters, purchase rights and shared settings. Position, visibility, pause, shortcuts, monitor range, mirroring and hover/idle frame options stay local to each Mac. TestFlight data does not transfer to the regular release.

Where do I change toys and display settings?

Completing custom characters progressively unlocks toys; toys are not sold separately. One toy is shown at a time. Adjust character size, speed and movement range and overall transparency. Set the quick menu to None if you prefer.
