This week: Hold. Nothing changes.
Coming to iPhone and Android.
How it works
Four steps, and only one of them is weekly.
Step 1
Pick a goal. Get a date.
Lose, gain, recomp or maintain. A few questions turn that into a target weight and a projected date — before you make an account.
Step 2
Check in once a week.
Two photos, front and side, and your weight. Around ninety seconds, on the same day each week.
Step 3
Read the verdict.
Whether it is working, and the one thing to change. When the week is not clear enough to call, it says so instead of guessing.
Step 4
The target corrects itself.
Your calorie number is re-fitted to what your weight actually did. A wrong estimate becomes the app's problem to absorb, not yours to fix.
Why a scale is not enough
Recomp looks like failure on a scale.
Losing fat and adding muscle at the same time barely moves your weight. Six weeks in, the number is roughly where it started — and that is exactly the point at which most people decide it is not working and stop.
A weekly read that only sees the scale agrees with them. Chisl reads the photographs alongside the number, and where the two disagree it tells you they disagree rather than picking whichever one makes the better headline.
“Not enough to call yet.”
That is a verdict Chisl is willing to give. It is the reason to trust the weeks when it gives you a different one.
What it is not
The omissions are the product.
No food database.
Photograph the plate or type a sentence. There is nothing to search and nothing to scan.
No workout log.
No sets, no reps, no history to keep up with between check-ins.
No body-fat percentage.
It reports change. It will not print an absolute number it cannot stand behind.
No editing the estimate.
If a meal reads wrong, the app corrects itself against your weight trend. Getting it right is its job, not yours.
Every one of those is a decision, not a backlog item.
