Free on iOS and Android. Create your account and tell the coach about your running — it takes about two minutes, and you just talk to it.
Settings is the last tab along the bottom. The referral row sits in the very first card, right under your name.

If you copied the code above it is already on your clipboard, and Ranner fills it in for you. Tap Redeem and your free trial jumps from 5 days to 14 on the spot.

Ranner asks about your goal, your week and your injuries, then writes the sessions, paces and heart-rate zones around them.
Garmin, Apple Health, Strava, COROS, Polar, Suunto and WHOOP sync on their own. You run, it reads the run.
Miss a session, sleep badly, turn up sore — Ranner rebuilds the rest of the week around it instead of nagging you about it.
Calories and macros that move with the session you have that day. Log a meal by talking to your coach or photographing the plate.
