Track your nutrition the way humans have measured food for thousands of years—with your hands. No barcode scanning. No complicated calorie counting. Just simple, sustainable tracking.
At Simage, we're on a mission to build products we actually want to use ourselves. Staying healthy is important to us, but we're tired of expensive meal tracking apps that charge $100+/month to scan barcodes and obsess over exact calorie counts. That level of precision isn't sustainable—and for most people, it's not necessary.
Our Hypothesis: if we can track 80% of our food correctly and consistently, we'll get 80% of the results (hopefully).
We built HandFull on a simple philosophy: measure with your hands, not a food scale. Your palm, your fist, your thumb—these are the only measuring tools you need. This approach is based on the D1 Training nutrition program, which prioritizes consistency over perfection.
We're so sick of fitness and healthcare tools being behind expensive paywalls, only to find they're overly complicated and require you to change your whole life to use them. So we made this free for everyone. Pay what you want, if you want.
Four steps. That's it.
Take a quick picture of your meal. This helps you remember what you ate and share with others for accountability.
How many palms of protein? Fists of carbs? Thumbs of fat? Quick visual estimates—no measuring cups needed.
Tap in your portions. Track against your daily plan. See your progress at a glance.
Share with your trainer or nutritionist (if you're lucky enough to have one), or with friends and family to help keep you accountable.
Your hands are the only measuring tools you need
