Frequency: tuning how often the past visits
The right cadence is personal — a memory every half hour is one person's delight and another's noise.
How it works
Bubbles In Time works offline. There is no server, no account and no sign-up — your photos never leave your phone.
Four intervals ship: 30 minutes, 1 hour, 2 hours, 4 hours. Android enforces a minimum interval floor and BIT respects it, which also keeps the battery story boring. Start at 1 hour; most people find their setting within a week.
Getting the most from it
Cadence psychology: shorter intervals suit rich, deep pools (variety prevents repetition-fatigue); longer intervals make each visit an event. The 4-hour setting approximates 'a few good moments a day' — the slow-drip school.
