How many calories did that workout actually burn? Pick the activity, set minutes and weight — get a research-based answer in seconds. No watch or sensors needed. "How many calories did I just burn?" CalsBurn answers that question in three taps: pick the activity, set the minutes, see a research-based estimate. No Apple Watch, no chest strap, no heart-rate sensor, no account. Most calorie apps track what you eat or count your steps. CalsBurn does one job: it estimates the calories a workout burned, using the same MET method exercise scientists use — MET x body weight x duration — with every MET value transcribed from the 2011 Compendium of Physical Activities (Ainsworth et al.). The formula, a worked example and the full citation are one tap away inside the app. WHAT YOU GET • An answer before you even log — the kcal estimate updates live as you adjust minutes and body weight, so "45 min of brisk walking" becomes a number before you commit it • 80+ activities with published MET values — running by pace, cycling by speed, swimming by stroke, gym machines, yoga, 20+ sports, even shoveling snow • Today's total and your 7-day total waiting at the top of the screen every time you open the app • Bar charts plus a per-activity breakdown that shows where your calories actually went • An optional daily kcal goal with a streak counter — and the streak doesn't break just because today isn't over yet • Pin your go-to workouts for one-tap logging, edit or backdate any entry, and export the whole log as CSV PERFECT FOR • Gym-goers who lift, row or do circuits — the workouts step counters can't see • Walkers, hikers and casual cyclists who don't own a fitness watch • Anyone managing a calorie deficit who needs the exercise side of the ledger filled in • Skeptics who want to know where a calorie number comes from — the source is printed in the app WHY NOT JUST USE A WATCH? You don't need an expensive wearable to learn that 30 minutes of moderate cycling burns roughly 280 kcal at 70 kg. Wearables estimate too — they just hide it behind a sensor. CalsBurn is honest about what it is: it shows an estimate built on published averages, labels it as an estimate, and explains that individual burn can differ by 20-30%. It is a fitness log, not a medical device, and it gives no dietary advice. PRIVATE BY DEFAULT Everything you enter — weight, goal, every session — lives in a database on your iPhone. No account, no server, no analytics, no ads, no tracking. The app never asks for Apple Health, your location or notifications. Delete the app and the data is gone; export it first as CSV if you want a copy. FULL ACCESS CalsBurn Pro unlocks the complete 80+ activity catalog and the 30-day history view. Pick the plan that fits: Weekly, Yearly, or Lifetime (pay once, keep it forever). Every plan unlocks the same features. Open CalsBurn after your next workout and finally put a number on it.
