FitDIY

Everything the big trackers paywalled, free: barcode scans, adaptive calorie & macro targets, full training log. No account, no ads, no data collection. Ever.

FitDIY is the do-it-yourself fitness tracker: one private app for everything you train and everything you eat, built for people who run their own program.

FOOD, WITHOUT THE FRICTION

• Log a meal in seconds: scan a barcode, tap a favorite, or enter it by hand
• Daily calories and protein tracked against your targets, with carbs and fat alongside
• Set a goal weight and pace, and FitDIY suggests daily calories and a macro split from your body stats, your planned training week, and your average steps
• The suggestion recalibrates from your real logs over time — your targets learn you

WEIGHT, AS A TREND

• Weigh-ins become a smoothed trend line, not daily noise
• Projection to your goal weight at your current rate
• Smart-scale entries sync in from Apple Health

TRAINING, YOUR WAY

• Strength: log sets with reps, load, and RIR; double progression suggests when to add reps and when to add load
• Cardio: runs, intervals, bike, row — logged and mirrored to Apple Health
• BJJ: sessions with rounds, intensity, and soreness; recovery flags when hard days stack
• A weekly plan you own, with a ramp-in for coming back from a layoff

SEE IT, REVIEW IT

• Record lifts and rolls; trim, slow-mo, and scrub frame by frame
• Progress photos in a private, app-local gallery
• Reflections: a quick good/bad and a note after any session
• Reports: chart any metric, overlay two, and see how they move together

YOURS, FULL STOP

• No account. No ads. No analytics. No cloud.
• Everything lives on your device; Apple Health sharing is opt-in and under your control
• Delete any entry, or everything, anytime

FitDIY reads and writes Apple Health data (weight, workouts, steps) only with your permission and only for the features above. Estimates are labeled as estimates — you can always override them.

Product data from Open Food Facts (ODbL) and USDA FoodData Central.
