Does Android have an 'on this day' photo feature?

Not as a system feature. Google Photos offers algorithmic Memories if you use its cloud, and some brand galleries add flashbacks. For an on-device version you control, Bubbles In Time floats the memories you chose, no cloud required.

The longer answer

Bubbles In Time is the Android app this applies to — your own photos drifting over any app, on-device, $2.99 once with no subscription, no ads and no cloud.

The 'on this day' habit is worth keeping — the question is whether an algorithm curates it or you do.

How Bubbles In Time handles it

Bubbles In Time draws from your own gallery — family, friends, pets, places — and shows them as translucent bubbles over any app, then lets them go.

Add the photos, videos, or message threads that matter to the in-app gallery, grant the one-time overlay permission, and pick a frequency from every 30 minutes to every 4 hours. From then on, memory bubbles drift over whatever you're doing — tap to open, swipe to dismiss, pause the whole layer with one switch whenever you need stillness. Everything runs on-device: no account, no uploads, no ads, $2.99 once.

Worth knowing

The rotation rewards curation over volume — twenty photos you love beat two hundred you tolerated. The Mystery Photo option keeps genuine surprise in the mix, and because nothing depends on a server, the whole experience works identically offline, abroad, and on every modern Android phone.
