Muscle tracking

See every muscle
you've trained.

The body map shows exactly which muscles have been worked this week — and which ones are overdue. No spreadsheet. No guesswork.

Calorie engine

Math you can
actually audit.

Every calorie number in Certovis is NET — TDEE is never double-counted. The metabolic adaptation engine accounts for the hormonal slowdown that kicks in after 90+ days of dieting — the same effect documented in diet research but ignored by every other app.
