Imports that keep the detail
Routes, laps, pace, heart rate and cadence survive the move where the source file has them. An imported run behaves like one you recorded, rather than a row with a distance on it.
Feature: sync and imports
Bring your history. Take it with you if you go.
Switching apps usually means abandoning years of training. It shouldn't. Import what you've already got, sync what your phone and watch already collect, and keep the door open on the way out.
iPhone and Apple Watch · Android and Wear OS in beta
- Hevy CSV exports import directly into your history.
- Strava connects over its API so new activities arrive on their own.
- Runkeeper archives upload in one go.
- Individual .GPX, .TCX and .FIT files work for one-off workouts.
- Apple Health and Health Connect for steps, distance, calories, heart rate and body measurements.
How it fits together
Imports that keep the detail
Strava keeps arriving
Connect once and new activities sync on their own. You aren't re-exporting a file every few weeks to stay current.
Health data both ways
Apple Health on iOS and Health Connect on Android, covering steps, distance, active calories, heart rate and body measurements, so what your phone and watch already know doesn't have to be retyped.
Leaving is allowed
Export your training history whenever you want. We'd rather earn the next month than trap you in it.
Questions
Before you switch.
Can I import from Hevy?
Yes. Export your data from Hevy and upload the CSV. Your workouts, exercises and sets come across into your TandemFit history.
Does Strava sync automatically?
Yes. Connect your Strava account and new activities import on their own, rather than you exporting an archive each time.
What file formats can I upload?
.GPX, .TCX and .FIT, including gzipped versions, plus Strava and Runkeeper archive exports.
Can I get my data back out?
Yes. You can export your training history at any time, and request account deletion from the support page.
