32 cardio forms, each with its own input
Most apps know one cardio form: time and calories, done. That works for nothing. A stepmill measures floors and steps per minute, a rower distance and split, a stationary bike resistance and cadence, a treadmill speed and incline.
Athverge models 32 forms of cardio separately, from machines to an outdoor ride and skipping rope, each with the fields that genuinely belong to it. You type over what you see instead of translating it into a form that was not made for it, which is why your log can still be compared with itself six months later.
Heart rate zones via Karvonen
Zones based on "220 minus your age" ignore where you started. The Karvonen formula uses your heart rate reserve, the gap between your resting and maximum heart rate, which shifts your zones to where they belong for you.
The fitter you get, the lower your resting heart rate, and the more your zones move with it. Zone 2 stays actually zone 2, instead of slowly turning into something harder without you noticing.
Live heart rate while you train
A Polar H10 pairs over bluetooth directly with your phone and streams your heart rate live while you train. You see which zone you are in at the moment it matters, not afterwards.
Alongside that, the Withings, Polar, Oura, Fitbit and Health Connect integrations pull in your steps, sleep, heart rate and calories burned. Every connection is one you make yourself, and one you can revoke at any moment.
Outdoors, with a privacy zone around your home
You record an outdoor session with GPS: your route on the map, your splits below it. A privacy zone sits around your home address, so a route does not visibly start or end there.
Location is only used during a session. Nothing runs in the background, and the app only requests the permission for that.
Intervals and the Cooper test
The interval player counts your blocks down so you are not watching a clock. The Cooper test is in there as a fixed measurement: twelve minutes, as far as you can, and a result you can still compare against in six months.
Your watch measures it, Athverge acts on it
A recovery score is only worth something if something happens with it. Athverge computes one from heart rate variability and resting heart rate, set against your own baseline band, plus your sleep and your check-ins. A wearable helps, but is not required: even without a strap or watch there is a score.
On a heavy day the workout player makes one proposal: one working set fewer per exercise today. One tap, and you decide. Nothing ever changes automatically, and "no" is a full answer.
Sleep, zones and the 10% rule
Per session your heart rate curve and time per zone are ready; per night your sleep stages, if your wearable measures them. And the app watches your weekly cardio volume against the 10% rule: grow faster than that and it says so, before you notice it yourself.
