The battery story: why a floating layer stays light
Overlay sounds heavy; in practice, network sync is what drains phones, and BIT has none.
How it works
Bubbles In Time works offline. There is no server, no account and no sign-up — your photos never leave your phone.
The layer wakes at your chosen interval, renders one lightweight bubble, and sleeps. No background uploading, no location, no sync engine — the costly subsystems simply aren't present.
Getting the most from it
Android's own interval floor caps wake frequency; the result is a memory layer that doesn't register in battery stats the way any cloud-connected app does.
Quick answers
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.
Is Battery & Performance included in the $2.99 price?
Yes — every feature ships in the single one-time purchase; no tiers, no unlocks, no subscription.
Does the app upload or share my photos?
No. Memories stay on your device; the app has no account system and its Play listing declares no data shared.
Do bubbles interrupt what I'm doing?
No — bubbles float without stealing focus. Tap to open a memory, dismiss to continue.
