A free cardio GPS tracker inside your gym app.

Why most gym apps ignore cardio

The typical workout tracker is built around a single question: how many sets, reps, and kilos? That framing works for a pure lifting log, but most people who train do more than lift. They run to work, cycle on weekends, walk as active recovery, or follow a hybrid program that deliberately mixes strength and conditioning.

The usual answer to this gap is a second app. You use one tracker for the gym and Strava — or a running app of your choice — for everything else. That split is functional, but it creates friction: two apps to open, two histories that never talk to each other, and no easy way to see how a long run on Tuesday affected the squat numbers on Wednesday.

Some apps offer a premium cardio module as an add-on. Others integrate with a wearable ecosystem and charge accordingly. The genuinely free option — a single app that covers both lifting and GPS cardio at no cost — is rare enough to be worth pointing out when it exists.

What GPS cardio tracking actually does in SammaGym

When you start a cardio session in SammaGym and select GPS mode, the app records your location continuously using your device's built-in GPS. This requires location permission — you will be prompted the first time you use the feature. The app does not use location for anything other than the active cardio session you have started.

• Distance. Total distance covered is tracked in real time and shown on the session screen as you move.
• Pace. Current pace (time per kilometre or mile) updates live so you can see whether you are on track mid-run.
• Elapsed time. A running clock for the full session duration.
• Route map. Your path is drawn on a map as you move. After the session ends, the full route is saved and visible in the session summary — useful for reviewing where you went and comparing different loops.
• Session summary. When you finish, SammaGym shows total distance, average pace, and your route in one view. The session is saved to your training history automatically.

GPS cardio sessions in SammaGym work for outdoor runs, walks, hikes, and bike rides — any activity where you move through real space and want a record of where you went and how far.

Indoor cardio: manual logging

GPS does not work indoors in any meaningful sense. Treadmill runs, stationary bike sessions, rowing machine efforts, and elliptical workouts do not produce a real location trace — the device sees you moving nowhere.

For indoor cardio, SammaGym uses manual logging. You enter the distance you covered (from the machine's display or your best estimate) and the duration. The session is saved in exactly the same format as a GPS session — it appears in your history, shows up in your cardio volume over time, and sits alongside your strength sessions in a unified log.

Manual logging also works if you simply prefer not to enable GPS permissions, or if you are running an outdoor session with GPS turned off. You lose the route map and the automatic distance measurement, but the core log entry — date, duration, distance, notes — is preserved.

One history for strength and cardio

The practical value of having GPS cardio inside a gym app is not the GPS itself — it is the shared history. When lifting and cardio sessions live in the same place, patterns that are invisible across two apps become visible.

You can scroll back through a month of training and see at a glance: three strength days, two runs, one long walk. You can notice that the week your squat stalled was also the week with two hard 10 km runs. You can build a hybrid program — say, four gym days and two cardio days — and track compliance for both modalities in a single history rather than cross-referencing two apps.

This matters more as your training becomes more structured. Beginners often feel the cardio-versus-lifting split is artificial, and it is: athletic performance depends on both, and programming them together requires seeing them together.

For a deeper look at SammaGym's full feature set, see the features overview. For a wider comparison of free workout trackers, the best free workout tracker guide covers several options with the same honest methodology.

Free with no subscription

GPS running apps with meaningful features typically fall into two pricing categories: free with ads, or subscription-gated after a trial. The major running apps charge a monthly or annual fee for features like route history, training plans, and advanced pace analysis.

SammaGym is free, and the GPS cardio feature is not behind a paywall. The same is true for the strength tracking side: auto-regulated progression, previous-set-inline logging, progress photos, and personal record tracking are all included at no cost. There are no ads at launch.

That combination — free GPS cardio tracking and free strength tracking in one app — is the specific gap SammaGym fills. If you currently pay for a separate cardio app and a separate gym app, or use a free app with limited features on one side, it is worth testing whether a single free tool covers both.

• No subscription required for GPS cardio or any strength feature.
• No ads at launch. Sessions are not interrupted by interstitials.
• Offline-first. Strength sessions and cardio logs are stored locally on your device. You do not need an internet connection to start a session.
• PWA. SammaGym installs from your browser as a Progressive Web App — no app store required. Add it to your home screen from app.sammagym.com.

How to start your first GPS cardio session

Getting from zero to a recorded GPS run takes under two minutes.

• 1Open app.sammagym.com on your phone. If you have not installed it yet, tap your browser's share button and choose 'Add to Home Screen'.
• 2From the home screen or the session menu, start a new session and select cardio mode.
• 3Choose your activity type — run, walk, ride, or other. For outdoor GPS tracking, make sure location permission is enabled when the browser or app requests it.
• 4Tap start and begin moving. Distance, pace, and elapsed time update live on screen.
• 5When you finish, tap stop. Review the session summary showing total distance, average pace, and your route map.
• 6The session is saved automatically to your training history alongside any strength sessions.

For indoor sessions, follow the same flow but select manual entry when prompted. Enter the distance from your machine's display and confirm the duration. The log entry is saved in the same format.

If you are evaluating SammaGym as a complete training tool, the features overview walks through the strength side in detail — auto-regulated progression, rest timers, and the coaching toolkit.
