Why does it matter?
Bubbles In Time works offline. There is no server, no account and no sign-up — your photos never leave your phone.
It's the difference between visiting a museum and living in a house with photos on the walls. Floating overlays are currently the most ambient form Android offers.
Where does the term show up?
You'll meet 'ambient memory' across the growing space of photo-resurfacing and ambient-memory tools on Android — and in Bubbles In Time, which implements the concept on-device: photos, videos, and message threads floating over daily phone use, no cloud, no account, $2.99 once.
Quick answers
