Finally, a calorie tracker that works the way humans actually think about food. No more hunting through databases or measuring every grain of rice.
"I grabbed a burger and fries" works perfectly. No need for "4 oz grass-fed beef patty with 2.3 oz of sweet potato fries." Our AI understands how real people describe food.
Take a quick photo and forget about it. While you're enjoying your meal, our AI is already calculating calories. No scanning barcodes or searching databases.
Ate something 3 hours ago? Just tell your Apple Watch "I had a sandwich earlier." 8Book remembers so you don't have to stress about perfect timing.
Raise your wrist, say "I had coffee and a muffin," lower your wrist. Done. That's the entire process. No phone fumbling required.
"Pizza," "tacos," "mom's spaghetti" - speak like a normal human. No more translating your meals into nutrition-speak.
Home screen widgets show your progress without opening the app. Because the best calorie tracker is the one you barely think about.
Real feedback from people who were tired of complicated food logging, AKA forgetting to log 🙃
"I literally just say 'breakfast burrito' and it's logged. No more spending 10 minutes searching for 'whole wheat tortilla with cage-free eggs.' This is what food tracking should have been all along."
"I can tell my watch 'had protein shake and banana' while still at the gym. By the time I'm in the car, it's already calculated and synced. Zero friction."
"I snap photos of every meal anyway for Instagram. Now those photos automatically become calorie logs too. It's like having a nutrition assistant who never judges my choices."
