Cardio in GYMKA: GPS Runs, Logged Sessions and Step History

Workouts → Cardio handles everything that is not a barbell: runs, walks, cycling, swimming, rowing, football, boxing and more. It has two ways in — track a session live, or log one after the fact.

Tracking a run live

Track Run starts live GPS tracking. It follows your route, distance and pace as you go, and when you finish it saves the session with the route attached. Saved runs show a small route trace in your history; tap it for the full map.

Logging a session manually

Log Cardio opens a form: pick the sport, enter the duration, and add distance if the sport has one. Everything else is optional, and each optional field sharpens the calorie estimate:

• Effort — easy, moderate or hard, for sports where intensity varies more than pace.
• Incline or elevation gain — the metabolic cost of climbing is real and significant.
• Average heart rate — if you have it from a watch or strap, it takes priority over everything else.
• Date and time — defaults to now, so you can backdate a session you forgot.

How the calorie number is produced

There is no AI guesswork here. Walking and running use the ACSM equations, which take pace and incline into account. Other sports use validated MET values scaled by your effort. Elevation gain adds the cost of climbing. If you supply an average heart rate, GYMKA uses a heart-rate-based model instead, because that is the most accurate input available. Everything is personalised to the weight, height, age and sex on your body profile.

History and editing

The History button opens your full cardio record, grouped by day with a per-day calorie total. Filter to the last 7 days, 30 days or all time, and read the totals strip for sessions, time, distance and calories over that range.

Any session can be edited — sport, duration, distance, elevation, heart rate, calories and even the date it happened — or deleted, or shared as a Strava-style image card.

Choosing what the tab shows

The Edit link opens a customizer for the Cardio tab itself. Switch off the weekly summary, the Track Run or Log Cardio buttons, the Apple Health and Steps panels, or switch on a preview of your recent sessions. History is always available.

Steps, on iPhone

On iPhone the Steps panel reads your step count directly from the motion coprocessor — the same source Apple's own Fitness app uses. It needs no Apple Health connection and no setup beyond granting Motion & Fitness access.

• A live counter for today, which updates as you walk and is correct even for time the app was closed.
• Step history: a bar per day, tap one to read that day's steps, distance and estimated burn.
• An optional button to fold today's step burn into your daily calorie total.

The history is independent of the calorie log — it shows what your phone recorded whether or not you ever add it to your calories. The 7-day range comes from the phone itself; connect Apple Health and a 30-day range appears, because Health keeps a longer record than the motion chip does.
