How to read an Evolt 360 report
An Evolt 360 scan prints twenty-odd numbers and almost no explanation. Most of them are measurements of your body. A few at the end are not — they are advice derived from a goal somebody picked at the kiosk, and they are worth separating out.
The headline numbers
Skeletal muscle mass (SMM)
The muscle you can train, in kilograms. Not the same as "lean mass", which also includes organs, bone mineral and water. SMM is the one to watch across scans — if it holds while body fat falls, you are recomposing rather than just losing weight.
Body fat mass and body fat %
The same quantity twice. The percentage moves when either the fat or the total weight changes, which is why it can fall on a week you gained fat and more muscle. Read the kilograms alongside it.
Visceral fat rating
An index, not a weight — the fat around the organs rather than under the skin. It is the figure with the clearest link to metabolic risk, and it responds to training and diet faster than the scale does.
The water numbers, which confuse everyone
Total body water (TBW) splits into intracellular fluid (ICF, inside your cells) and extracellular fluid (ECF, outside them). The ratio between ECF and TBW is the one clinicians look at.
A ratio around 0.36–0.39 is the usual range. A drift upward means proportionally more fluid sitting outside the cells, which can accompany inflammation, poor recovery or simply a hard training block. It is a trend to watch across scans, not a diagnosis from one. If it is persistently high, that is a conversation with a doctor, not with an app.

Segmental analysis
Lean mass measured separately for each arm, each leg and the trunk. Useful for spotting an imbalance after an injury, or checking that a programme is reaching the half of you that usually gets less attention. Small left–right differences are normal; a persistent gap of more than about 10% is worth looking at.
The numbers that are advice, not measurement
Near the end, most Evolt printouts carry a calorie target and a protein target — often labelled something like "21. CALORIES" and "22. PROTEIN". These are not measurements of your body. They are derived from a goal selected on the machine before the scan, and they will change if somebody picks a different goal.
Keep them separate from the measured values. A target that came from a kiosk six weeks ago, sitting in your tracker next to the target you actually set, is how people end up following neither.
Getting the numbers off the paper
Evolt reports are generated PDFs with a real text layer, so the figures are already text — no typing, and no AI needed to read them. Fitlectic parses the PDF on your phone: fat, muscle, visceral fat, ICF, ECF, the ECW/TBW ratio, segmental lean mass, and the machine's own reference bands so each value is coloured against the right range.
It files the entry under the date and time printed on the report, not the day you uploaded it — so three old scans uploaded in one sitting land on three different dates and your trends stay true. And it deliberately ignores the calorie and protein recommendations, for the reason above.
