WaterTracker makes it easy to not only track the amount of water you've had each day, but also to set targets, see statistics, and more. And best of all, it is completely free! No in-app purchases, no subscriptions - ever! Featuring an Apple Watch app, home and lock screen widgets, Shortcuts capability, Control Centre widgets, and more, WaterTracker is your one stop-shop for keeping track of your water. Set your target, and start logging today. With WaterTracker you can create presets - a set amount with its own name, icon, colour, and unit - so that you can easily log that morning glass of water, or that bottle after your run. It also connects to Apple Health, and can read your water intake from other apps, and can write to Apple Health as well. You can easily export your water, target, and preset data in CSV format, or to a PDF in the form of reports, showing your weekly, monthly, or all-time statistics. Please contact Support@LifeTracker.Studio with any concerns, bugs, issues, or suggestions, or visit LifeTracker.Studio for more information on WaterTracker or any of our other apps. Happy Tracking!

A HIIT and interval timer that stays out of your way. No ads. No tracking. Nothing interrupts your workout. WHY INTERVALFLOW β€’ No ads, ever β€” not a banner, not a video, not between rounds. Your countdown is never covered and your audio is never cut. β€’ No tracking β€” no analytics, no advertising identifier, no account. Your workouts stay on your device. β€’ Live Activity and Dynamic Island β€” the current phase, the countdown, and the round stay on your Lock Screen. Check mid-set without unlocking. BUILT FOR REAL WORKOUTS β€’ Ready-made presets: Tabata, HIIT 40/20, EMOM, boxing rounds, and multi-set circuits. β€’ Custom builder: prepare, work, rest, rounds, sets, rest between sets, and cooldown β€” to the second. β€’ A countdown you can read across the room, with each phase in its own colour: work, rest, get ready, cooldown. β€’ Sound, haptics, and voice cues, so you can keep your eyes off the screen and on the set. IT KEEPS THE RECORD β€’ Every finished session is logged on its own β€” time, rounds, and an estimate of calories. β€’ A daily streak and a weekly count, for the weeks when motivation needs a number. Made for HIIT, Tabata, cross-training, boxing, running intervals, stretching, EMOM, and circuits β€” at the gym or on your living room floor. Open it, tap a preset, and start. That is the whole app.
