iPhone
Snap a photo of your meal and get calories, protein, carbs and fat in seconds. New Workout Recommendations. Now fully redesigned, with dark mode and a brand-new icon.
Point your camera at your plate. Ratiō reads it and returns calories, protein, carbs, and fat in seconds.
But here's what makes Ratiō different: it shows its work.
Most AI food trackers hand you a number and hope you don't ask questions. Ratiō breaks down every item it identified, the portion it estimated, and how it got there. Disagree? Edit it in two taps. Your correction sticks, and your log stays honest.
HOW IT WORKS
• Snap a photo of any meal — home-cooked, takeout, restaurant, whatever's in front of you
• Ratiō identifies each component and estimates portions
• Review the breakdown, adjust anything that looks off
• Log it and move on
BUILT FOR PEOPLE WHO ACTUALLY TRACK
• Full macro breakdown on every entry, not just a calorie total
• Item-level editing — fix one ingredient without redoing the whole meal
• Manual entry and quick-add for the days you already know the numbers
• Daily targets you set, not targets an algorithm decides for you
• Clean, fast interface that opens straight to the camera
NO GAMES
• Clear pricing before you sign up
• Free trial with an obvious cancel path
• No fake precision, no invented confidence, no ads
Tracking only works if you keep doing it. Ratiō is built to take five seconds, not five minutes — so you actually still be using it in month three.
