Runf: Run with your Pet

About this app

Some runs you do for yourself. The rest, you do because something is waiting for you. Runf gives you a pixel-art companion that runs beside you, matches your pace, and grows only from the distance you actually cover. There is no level to grind and nothing to tap. The kilometres are the whole game. A PET THAT GROWS BY RUNNING Your companion changes through three drawn forms as its distance bar fills. Nothing else moves it — no daily tasks, no shortcuts. A grown pet is a record of the mornings you got out of bed. NINE COATS, THREE TIERS Every pet is born in one of nine coats. Common is the plain brown one. The saturated colours are uncommon, and the pale ones are rare — anyone who sees one knows what it took. The colour is rolled when you adopt, and it never changes. APPLE WATCH, WITH OR WITHOUT YOUR PHONE Leave the phone at home. The watch records GPS, heart rate and distance on its own, and your pet runs on your wrist wearing exactly what it wears on the phone. Start, pause and stop from either side. TREADMILL RUNS COUNT Switch to indoor and distance comes from your steps instead of GPS, on the phone and on the watch. RUNS FROM ANYWHERE Recorded with a Garmin, a Coros, or Strava? If it reaches Apple Health, it counts towards your pet, tagged with where it came from. Nothing gets counted twice. THIRTY BADGES, NINE BELTS First run, first 10K, a full marathon, a week without missing a day. Every badge is dated to the run that earned it. The belt on your profile climbs from white to black on total distance alone. WHAT YOU RUN FOR Gems come from kilometres. Spend them on a satchel for your pet's back, a flower that travels with you, or weather that falls across your home screen. One item, one pet. YOUR PETS FOLLOW YOU Sign in with Apple and your pets, runs and badges come back on a new phone. Runs record whether or not you have signal — a tunnel, a mountain, a flight — and go up when you are back. No ads. No streak you can lose by missing a day. Just the distance, and something to run it with. Terms of Service: https://runf-app.netlify.app/terms.html Privacy Policy: https://runf-app.netlify.app/privacy.html
