SpeedFIT — Speediance to .FIT
FitLab Tech
Your Speediance workouts as standard FIT files for Garmin Connect.
If you own a Speediance Gym Monster and want your strength training data in Garmin Connect, SpeedFIT gives you full control. No Garmin password needed — just sign in to Speediance, pull your workouts, and export each one as a standard .FIT file you upload yourself. The .FIT format is supported by other fitness platforms too — feel free to try uploading anywhere that accepts standard FIT files.
WHY MANUAL EXPORT
✓ Your Garmin login stays with you — SpeedFIT never asks for it
✓ Upload directly to Garmin Connect — or try other platforms that accept .FIT
✓ Decide which workouts ship and which stay private
✓ One file per workout — keep a backup, share with a coach, or upload from another device
WHAT'S IN EACH FIT FILE
✓ Original Speediance workout name preserved
✓ Per-set details: reps, weight, work time, rest time, volume
✓ Workout stats: total time, work time, rest time, calories, total reps, total sets, total volume, power output (kJ)
✓ Heart rate samples over the workout timeline, with average, maximum, and per-set peaks
✓ Muscle group / body-part tagging — body heat maps populate correctly when you upload to Garmin
SMART EXERCISE MAPPING
Garmin's exercise library doesn't use the same names as Speediance. SpeedFIT picks the closest matching Garmin-compatible equivalent for every Speediance exercise (and the right muscle category, so heat maps populate correctly).
Not happy with our pick? Edit the exercise on whatever platform you upload to — your sets, reps, weight, and timing data are preserved either way.
APP FEATURES
✓ Export any Speediance workout as a standard .FIT file
✓ Files saved to your Downloads folder — share or upload from there
✓ Smart duplicate detection — never re-exports the same workout
✓ Encrypted on-device credential storage for Speediance
✓ One-time purchase ($14.99) — no subscriptions, ever
✓ See your real workout data before you buy: connect, browse, inspect every parsed metric
PRIVACY-FIRST DESIGN
SpeedFIT runs entirely on your phone. There is no SpeedFIT server. Your Speediance credentials and workout data never touch any system the developer controls — and SpeedFIT never asks for your Garmin login at all.
• Speediance credentials encrypted with AES-256 in the Android Keystore
• Network connections only to Speediance (HTTPS) — no third-party uploads
• No analytics, no advertising, no tracking SDKs
• Privacy Policy: https://speedfit-app.github.io/speedfit-legal/PRIVACY
HOW IT WORKS
1. Sign in to Speediance (one time)
2. SpeedFIT detects your workouts and shows every parsed metric
3. Tap a workout to inspect the full breakdown — see for yourself the data is correctly parsed
4. Unlock for $14.99 — one-time, no subscriptions
5. Tap Export — a .FIT file is saved to your Downloads folder
6. Upload to Garmin Connect, or try any platform that accepts standard FIT files
One-time purchase. No subscriptions. No recurring charges.
IMPORTANT NOTES
• Garmin Connect and Speediance are trademarks of their respective owners. SpeedFIT is an independent third-party utility, not affiliated with, endorsed by, or operated by either.
• SpeedFIT depends on the Speediance API. If Speediance changes their API, some features may temporarily stop working until an app update is released.
• .FIT is an industry-standard format published by Garmin. Compatibility with other platforms varies.
