What’s actually at the gym you’re walking into?
Every other tracker treats a gym as a name on a receipt. TandemFit knows what’s on the floor: the machines, the racks, where the dumbbells top out.
Questions
The things people ask before switching.
What makes TandemFit different from a normal workout tracker?
TandemFit uses your gym’s listed equipment to help plan workouts and find alternatives. You can also see recorded gym activity where data is available, and train with a partner while keeping workouts, cardio, and nutrition together.
Can I use TandemFit for just lifting or cardio?
Yes. Track lifting, running, cycling, or other supported cardio modes on their own, or combine them. Nutrition tracking is there when you want to track meals alongside your training.
What if my partner has a bad week?
The week still closes and you still get credit for what you did. You pick your partner for the following week by Saturday, so a quiet week costs you a week, not your streak. You can also train solo and keep every other part of the app.
How does the gym equipment data stay accurate?
Two ways. Gym owners can claim their gym and verify the list directly, which stamps it with a date. Everyone else answers one-tap questions between sets, so entries get re-confirmed by people standing in front of the equipment. Anything only one person has reported stays marked unconfirmed until others agree.
Can I bring my training history over?
Yes. Hevy exports import directly, Strava connects over its API so new activities sync on their own, and Runkeeper archives can be uploaded. Individual .GPX, .TCX and .FIT files work if you'd rather move one workout at a time, and you can export everything back out whenever you want.
Which platforms is TandemFit on?
iPhone and Apple Watch are live on the App Store. Android and Wear OS are in beta, and you can request an invite from the homepage.
Do I have to use the social side?
No. Tracking, gym data, guided sessions, health sync and imports all work on their own. Partner features are optional and available whenever you want them.
