Three apps for one workout
I started training seriously because I needed to lose weight. Within a month I was running three apps to record a single session: a notes app for sets and weights, the watch for heart rate, and a calorie tracker for meals.
None of them knew about the others. The set logger had no idea my heart rate hit 157 on the last squat. The calorie tracker knew I had eaten 2,165 kcal, but not that I had moved seven tonnes that evening. I kept switching apps mid-session and copying numbers between them, and I still could not answer the only question that mattered: is this working?
So I looked for one app that recorded the time on each set, the heart rate that came with it, and my meals — all in the same place. I never found it. I wrote it instead.
Every set, with its own time and heart rate
This is a real leg day. Across the top is my heart rate for the whole session, with a coloured band behind each exercise so I can see which movement pushed me where. Underneath, every set carries its own clock and its own heart rate — 120 kg × 15 reps at 106, then 112, then 121 by the third set.
The hack squats say it more bluntly: 140, 147, 148, 157, with the seconds stretching from 57 to 73 as I came apart. Fifty-seven minutes of work came out as 19 minutes in fat burn, 22 in cardio and 6 at peak.
That one screen is what I could not buy anywhere. It is the whole reason WristSet exists.
Food is the other half
You cannot train your way out of a bad week of eating, so meals had to live in the same app — and in the language I actually eat in. A Tam Jai noodle set, 譚仔過橋米線套餐, is 882 kcal, logged as its three parts instead of as a guess.
The day then adds up honestly: 2,165 kcal in, 1,924 out at rest, 588 from the workout, 361 from walking around. Balance, 709 kcal down. It also tells me what I would rather not hear — 20 kcal over target, 99 g of protein against a 194 g goal, and carbs well over the line.
A month is harder to argue with
One day proves nothing. July 2026 proves something: ten sessions, 12 h 42 m under the bar, 105.2 tonnes moved, and 6,016 kcal below maintenance — about three-quarters of a kilo of fat, if the arithmetic is kind.
The calendar keeps the bad days in view too. 3 July is still sitting there at +2,267 kcal, orange, permanent. I do not get to forget it, and that is the point.
