About

Exerzio

Read full description

Exerzio turns the workouts you already have into a map of your active life. Every run, ride, walk and hike in Apple Health is drawn on one map, so you can see the shape of where you actually go — not a list of numbers, but the territory you have covered. TWO WAYS TO SEE THE MAP Atlas shows your routes on one map, with no grid and no game. Tiles turns the world into a fixed grid of squares: pass through one during a workout and it is yours. The grid is the same everywhere and never moves, so a square you claimed years ago stays claimed. Chase new tiles, your max square, and your max cluster. BUILT TO STAY SMOOTH Workout routes are pre-rendered into a local pyramid of map tiles, so panning and zooming stays fast with thousands of workouts instead of redrawing every path each frame. YOUR DAY, YOUR HISTORY Today gives you steps, energy, distance and workouts at a glance. Activity is the health log — sleep, body measurements, hydration, mindfulness. Workout is your history, with personal records and the detail of every session. RECORD A WORKOUT Start a workout from the map and it records with its route, then saves to Apple Health so every app you use sees the same training. If something goes wrong mid-session, nothing is lost: the recording is preserved and can be finished later. DUPLICATES, HANDLED If two devices both wrote the same workout to Health, Exerzio recognises the duplicate and excludes it from totals, charts and share cards — without deleting anything from Apple Health. MAKE SOMETHING WORTH SHARING Create Studio turns your data into cards: a day, a week, a month, a single workout's route, or your explorer tiles. The workout share editor lets you frame the map by hand, choose a format for where it is going, and pick which stats appear. ON YOUR HOME SCREEN Widgets for today's progress, weekly trends, training, recent sleep and the atlas engine. Siri shortcuts for the things you ask often. SEND YOUR WORKOUTS TO YOUR OWN SERVER If you run Dreeve, connect it and Exerzio sends the workout types you choose straight from your iPhone to your own instance. You supply the address and the key. There is no Exerzio relay and no Exerzio account in between. YOUR DATA STAYS YOURS No account, no Exerzio server, no analytics and no advertising SDK. Your workouts are not published to iPhone-wide search, and Siri answers with distances and directions rather than addresses or coordinates. Map imagery is fetched as you browse, like any map app; your routes are drawn on your device and are never uploaded.

Verdict

The call

The clearest difference is in-app purchases: Custom Interval Timers at none against Exerzio's 3. Custom Interval Timers also leads on device support (3 vs 1) and iOS requirement (15.1 vs 26.1). Exerzio's advantage is ads (none vs shown) and update cadence (every 2 days vs every 4 months). On price there is nothing between them.
