Finally see which habits actually move your weight.
Most apps make you log every calorie and hope the number on the scale follows. GrubCal works the other way around. It watches what the scale says, notices what you did that day, and after a couple of weeks tells you what's really going on.
DISCOVER YOUR PATTERNS
After about two weeks of check-ins, GrubCal reveals insights like:
"After eating out, your weight is up 0.4 lbs the next day"
"You typically gain 0.5 lbs over the weekend"
"Days after a workout are your lowest weigh-ins"
The longer you use it, the sharper it gets.
WEIGHT THAT LOGS ITSELF
Connect a smart scale through Apple Health and your weight appears in GrubCal automatically. No scale? Type today's number in a second.
THREE QUICK TOGGLES
Did you eat out? Have drinks? Work out? That's the whole daily check-in. No food diaries, no portion sizes, no guilt.
SNAP YOUR MEALS (OPTIONAL)
Curious what a meal costs you? Take a photo and get an instant AI calorie estimate, then save it to Apple Health if you like. It's there when you want it and out of the way when you don't.
TRENDS YOU CAN READ
Clear weight charts over 30 days, 6 months, a year, or all time, with the behaviors overlaid so you can see cause and effect.
PRIVATE BY DESIGN
No account. No sign-up. Your weight and habit history lives on your device and is never sold or shared. Meal photos are sent securely for analysis only and are not stored by GrubCal.
