About this app

FREE BETA: YOUR DATA STAYS ON YOUR PHONE
During the beta, Nutshell Go stores everything it records only on this phone: rides, GPS tracks, heart rate, power and your settings. Nothing is uploaded to Nutshell or anyone else, and you don't need an account. Nothing is backed up either, so if you uninstall the app or reset, replace or lose your phone, your rides can't be recovered. Export any ride you want to keep from History.
Like every app on Google Play, Google may share install statistics and crash reports with us. These never include your rides.
When accounts and syncing arrive after the beta, we'll update this listing and ask you before anything is uploaded.

The app follows your phone's language, or you can choose one in Settings.

Nutshell Go supports power meter and heart rate training over Bluetooth. Mapping is built in and works offline — download the areas you ride and the map and route planner keep working with no signal.

Routes can be planned for you across road, MTB, gravel and trekking, each picking different surfaces. Or build your own, import a GPX to follow, and save any ride as a GPX to keep or export. Geotag photos to your GPX routes and share them with other Nutshell Go riders.

TRAIN TO POWER
• Intervals: a warm-up, then work and rest rounds by power zone, heart-rate zone or W/kg, with countdowns and beeps.
• Target pages: hold a power, heart-rate or W/kg target with colour cues and an alarm.
• Power test: pick a time and a wattage, and see exactly what you need to average.
• FTP test: ride 20 minutes, watch your projected FTP live, and update your zones in one tap.
• Best efforts: your peak, 5 s, 30 s, 60 s and 20-minute power for every ride.
• Dual-sided power meters: see your left/right pedal balance live.

RIDE VIDEOS
Overlay your ride stats on your own video clips: power, heart rate, speed, elevation and route, synced to the footage and ready to share.
