FastingWindow is the cleanest, simplest way to track intermittent fasting — no account, no subscription, no noise. Pick a schedule (16:8 or 12:12), tap Start Fast, and watch your progress in real time. A live ring shows exactly where you are in your fast, and as the hours pass you'll move through five metabolic stages — from initial digestion all the way to deep ketosis. Each stage is explained so you actually understand what your body is doing, not just how long you've been waiting.

A step counter with a sky — your steps big on your home and lock screen, over clouds that open as you walk. Your daily goal isn't 10,000. You pick a number that means something to you — 1,111, 3,333, 7,777 — and each one has its own sky. It starts quiet in the morning, widens as you walk, and opens when you arrive. WHAT YOU GET • Your steps on the home screen — four widgets to pick from • Your steps on the lock screen, under the clock • Calories and distance, on a quiet second line • A row of your past days, right under the number • The same number as the Health app — one count, everywhere FREE WHERE IT MATTERS The widget is free. Both screens, every style. No ads, anywhere in the app. No account, no sign-up, nothing to log in to. No Apple Watch needed — your iPhone has been counting all along. NOTHING TO SET UP Your iPhone counts your steps on its own, all day, in the background. Angel Step reads that count from the Health app, so the number here is the number there. You don't have to open the app for it to work. A DAY OFF DOESN'T BREAK IT Nothing turns red. Nothing tells you that you failed. If you have walked enough days in a row, the sky covers the gap for you, and you find out the next morning. There is no countdown, no ranking against anyone, and no line that says you are behind. THINGS THAT STAY Days you reach your goal leave something behind — small objects that gather on a shelf that is only yours. Nothing is bought, nothing expires, and nothing disappears if you stop for a while. WALK WITH SOMEONE Give someone your invite code. When they take their first walk, a sky opens for both of you — one neither of you could have opened alone. No leaderboard, no names, no scores. PRIVACY Your steps never leave this phone. Angel Step reads your steps from the Health app and sends them nowhere. There is no account, and no analytics about your walking. PREMIUM Angel Step is free, and it is whole without paying. Premium adds more skies to walk under, your sky out on the widget, and five covered days instead of three. Subscriptions renew until you cancel in Settings; the one-time purchase never renews.
