Habits, tracked locally. Shared only when you say so. Zen works offline. No accounts, no ads, no tracking, no subscriptions. Every habit, day, and note lives in a local database on your iPhone, and the app reads and writes it without a network. Start from 236 habits that are already worded, across 16 categories, or write your own. Pick the days it repeats, a start and end date, a reminder, an icon, and a color. Three kinds of goal: run a timer, count reps, or work through a series of rounds. The day completes when the work does. A running timer keeps going on the Lock Screen, in the Dynamic Island, and from the app icon. Habit strength turns your recorded history into a 0-100 estimate. Gains slow over time, misses lower it gradually, and skipped days stay neutral. Read it beside your current streak and a full year of completions. Complete a habit wherever you are. Five Home Screen widgets carry today, weekly progress, strength, streak, and history. Apple Watch runs the work itself: a timer that counts down, a counter with its tally, and a series worked round by round, with today's tally on the watch face. Ask Siri to mark a habit done. iPad lays the app out for its own width. Challenges are optional. Share a habit over iCloud with the people you invite. Everyone keeps their own habit, nothing is public, and there are no profiles. There is no Donado Labs server to hold your data, so the device is where it is. Optional sync passes it between your own Apple devices through your iCloud account, and you can take a copy of everything as a JSONL file whenever you want it, once, or kept up to date in your iCloud Drive.

You know exactly when you have to be out the door. Somewhere between the shower and your shoes, you lose track. outtimer only cares about one time: when you have to leave. It tells you how many minutes are left, out loud, while you're holding a toothbrush, a hair dryer, or a cup of coffee. WHAT IT DOES Set the time you need to leave and tap Start. That's the whole setup. Every 1 to 5 minutes (you choose), you'll hear "12 minutes left." For the last 10 minutes, Final spurt steps it up to every minute, so the deadline never sneaks up on you. When time's up, it rings. FOR WHEN YOUR HANDS ARE WET โข Keeps announcing with the screen off and the app closed โข Turns your music down instead of stopping it, so your podcast keeps playing underneath โข Vibration only, with three distinct patterns, for when someone's still asleep โข Lock Screen widget, Live Activity, and Dynamic Island: see the countdown without unlocking MADE FOR TIME BLINDNESS If you have ADHD, or you just can't feel 20 minutes slipping by, a silent clock won't help. You have to look at it, and looking is exactly what you forget to do. outtimer tells you instead. PRESETS Weekday mornings, gym nights, the school run. Each preset saves its own deadline, interval, and sound or vibration. Repeat it on the days you choose, or use it once and it turns itself off. NO SUBSCRIPTION One purchase. No ads, no account, no sign-up. Nothing gets uploaded, because there's no server. The only permission it asks for is notifications, and it still works if you say no. Put the phone down. We'll tell you.

Verdict
The clearest difference is price: outtimer at Free against Zen's $9.99. Zen's advantage is in-app purchases (none vs 1) and ads (none vs shown). On update cadence, device support and iOS requirement there is nothing between them.
