Athletica

GPS cycling & running computer

Every ride, measured. Read it at a glance.

Athletica turns your phone into a cycling computer, and a running watch too. Big, always-on numbers while you move, then a map of your route coloured by speed so you can see exactly where you flew, with records, goals and milestones to keep you going.

Coming soon toGoogle PlayComing soon toApp Store

No account needed. No ads, no tracking. Your activities stay yours.

Everything you need on the bike, and on foot

Built for riders and runners who want clear numbers they can trust, not a social network.

While you move

Live GPS speed

Current, average and max speed, distance and moving time, with a filter that keeps up when you sprint.

Rides and runs

Running mode shows pace, kilometre splits and best efforts, with its own records and settings.

Auto-pause

Stops counting at a light and picks up as you move on. Or let the clock wait until you set off.

Laps & auto laps

Press for a lap, or end one every 0.5 to 10 km, or each time you pass the start of a loop.

Voice, targets & fuel

Spoken updates you choose per sport, a nudge when you leave your speed or pace range, and reminders to drink and eat.

Race your best

On a route you've done before, the dashboard shows how far ahead or behind your fastest effort you are.

Climb & gradient

Live gradient and climb, from the barometer where your phone has one, so a change in the weather adds nothing.

Always-on dashboard

Eight faces and twelve themes, the air quality where you are, optional dimming, and it keeps recording with the screen off.

After the ride

Speed-coloured map

Your route shaded slow-blue to fast-red on Google Maps, linked to speed and elevation graphs.

Weather

Temperature, wind and rain for the ride, how much of it went into the wind, and the air quality and UV.

Share image

Your route and the stats you pick, over a full-quality photo you can crop, blur or zoom out, or a colour.

Edit & annotate

Name, notes and how it felt, switch between ride and run, and trim a forgotten stop off either end.

Calories

Estimated from the power you need: rolling, air drag and the hills, not just a speed table.

GPX & backup

Export any activity as GPX, import GPX from other apps, and back up everything to one file.

Sync with Google Drive

Optional: sign in with Google and your activities sync between phones through your own Drive.

Crash-safe

If your phone kills the app mid-ride, carry on where you left off, or save what was recorded.

Keep going

Personal records

Longest, fastest, top speed and most climbing, plus your fastest 5 to 100 km and best 5, 20 and 60 minutes on the bike and race distances on foot, each with your previous best.

Milestones

Badges for your first 100 km ride, a half marathon, a 1,000 m week, climbing Everest in a year and more.

Weekly goal & streak

Set a distance for the week. A ring shows what's left and how many weeks in a row you've made it.

Calendar & heatmap

A year of activities day by day, and every route on one map so the roads you use most glow brightest.

How it works

1

Start

Tap Start (on Android, also from the home screen widget or by long-pressing the app icon). The app waits for a GPS lock before it counts anything.

2

Ride

Mount your phone and go. Numbers stay readable at a glance, it pauses at every stop, calls out laps and keeps recording with the screen off.

3

Review

Hold Stop to finish. See your route coloured by speed, the weather, new records and milestones, then tap how it felt and share it.

Pick your dashboard

Eight layouts for the ride screen, set separately for rides and runs. Choose one in Settings or switch mid-ride, or build your own from 16 stats. Every one works in landscape too.

See where you were fast

After every ride, your route is shaded by speed with start, finish and top-speed markers, and the way out and back sit side by side. The map, speed graph and elevation profile are linked: pick a point on one and the others follow.

Your activities stay yours

Where you ride and run is personal. Athletica is private by design.

On your phone first

Routes, stats and settings are stored on your phone. No account is needed to record, review or back up.

Sync to your own Drive

If you sign in with Google, activities sync to a hidden app folder in your own Google Drive. There is no Athletica server.

No ads, no tracking

No analytics and no ads. Location is used only to record the activity you started.

Only what's needed

Maps are shown by Google Maps. Weather and air quality ask Open-Meteo for an area rounded to about 1 km, and can be turned off.

Read the full privacy policy

Numbers you can trust

Phone GPS is noisy. These are the rules the app uses so your stats reflect the ride, not the noise.

Smoothed, not slow

Doppler speed from the GPS chip through a Kalman filter, which smooths noise without lagging behind. Fixes less accurate than 20 m are ignored.

Real max speed

Impossible GPS jumps are filtered out first, so your max is simply the top of the speed graph you see.

Honest climb

The barometer, checked against GPS altitude over about ten minutes, so neither GPS wobble nor a change in the weather counts as climbing.

Moving time

Rides pause below 3 km/h and resume above 5 km/h, so traffic lights never count. Short GPS losses, like tunnels, keep counting.

Make it yours

Units

Kilometres and km/h, or miles and mph. Elevation follows in metres or feet.

Dashboard face

Classic, Big three, Speedometer, Digital, Speed focus, Map + stats, Splits or your own Custom face.

Themes

Twelve looks, from Volt lime-on-black to Ocean, Sunset, Forest, all-dark Violet Night and Forest Night, and plain Mono for bright sun.

Auto-pause speed

Set the speed below which the activity pauses, separately for rides and runs.

Keep screen on & dim

Keep the display awake, and dim it after 15, 30 or 60 seconds to save battery.

Voice announcements

Choose what's spoken and how often, separately for rides and runs, plus drink and eat reminders.

Map type

Road, satellite, terrain or hybrid Google Maps.

Sync

Sign in with Google to sync through your Drive, on Wi-Fi only if you like.

Body weight

Used only for the calorie estimate.

Pro tips

•Allow background recording when the app asks, so your phone doesn't stop a ride when the screen turns off.
•Wait for “Recording” before you set off, or turn on “Start when I move” and the clock waits for you.
•Tap the dashboard button next to Stats / Map to switch faces without stopping.
•On your summary, drag along the speed graph to scrub through the ride on the map.
•On Android, long-press the app icon for Start ride and Start run, or add the home screen widget to see your week at a glance.
•Hold the stop button to finish. A quick tap won't end your ride by accident.
