Bubl Timer is an interval timer for moments when you don't want to think. Each timer is a bubble. Tap it to start, tap again to stop, hold it for its history. That's the whole interface. Everything a timer needs is free. Bubl Pro is a one-time purchase that adds more fills, colours, symbols and alarm sounds. No subscription. MADE FOR SPACING THINGS OUT Set a bubble to the gap you want to keep, whether that's between coffees, breaks, feeds, sets at the gym, or anything else you'd rather not do too soon. The bubble fills as time passes and tells you when the wait is over, with a notification even if the app is closed. LIVING FILLS Choose what's inside each bubble: Liquid, Smoke, Snow or Crystals. Liquid drains as the time runs down; smoke thickens, snow piles up and crystals fall in one by one as it passes. They move when you move and squish against the edge of the screen like something real. THREE WAYS TO SEE YOUR BUBBLES Single shows one big bubble at a time. Pair lines them up two by two. Trio stacks three. Roll through them with a flick; the ones you park stay out of the way in the dock. ON YOUR LOCK SCREEN AND HOME SCREEN Every running bubble counts down in one Live Activity on the Lock Screen and in the Dynamic Island. Home Screen widgets show up to four bubbles in the small size and six in the medium, each with its ring and time left, plus Lock Screen widgets. YOUR OWN BUBBLES Add bubbles with any symbol, colour, time and fill. Hours with two buttons, minutes on a rail, from one minute to a full day. Hold a bubble in Edit to move it, park the ones you don't need, bring them back later. A HISTORY THAT SHOWS THE SHAPE OF YOUR DAY Every start is remembered. See it as a list, as Lanes (a 24-hour strip for each day), as a month of glowing days, or as a cloud of bubbles you can push around. MADE TO BE FELT A tick on every control, detents as you scroll, a pop when a timer ends. Set haptics to Full, Soft or Off in Settings. YOURS, AND ONLY YOURS No account, no sign-up, no analytics, no ads, no third-party code. Timers, history and preferences live on your phone, backed up only to your own iCloud so a new phone picks up where you left off. Alerts are local notifications scheduled on the device.
