About

Byte Coach

Read full description

Most calorie apps assume you want to be precise. Byte Coach starts from the opposite assumption. You already know when you've overdone it. You don't need to weigh the chocolate — you need to know you went over by roughly 1,000 calories and how to handle tomorrow. Opening an app for the seventeenth time to log exact grams is exactly what makes people quit. So Byte Coach works the way you actually talk: snap a photo, say it out loud, or type it the way you'd tell a friend. Your coach figures out the rest. Every morning: a recap of yesterday and a focus for today. Every midday: a quick check on where you stand. Every Sunday: a full week in review with charts. Not a ledger. A coach. KEY FEATURES • Photo logging — point your camera at any meal, anywhere in the world • Voice logging — speak naturally, your coach understands • Text logging — type it the way you'd tell a friend • Apple Health sync — steps, active calories, and weight flow in automatically • Garmin & Strava — workouts and activity sync daily • Morning summaries, midday nudges, weekly review charts • Exercise modes — track burns separately or subtract from your daily budget • 7 languages — English, German, French, Spanish, Italian, Portuguese, Dutch • Challenges — compete with friends on water, protein, steps, or calorie adherence PLANS Start with a 7-day free trial of Base. Cancel any time before it ends. Base ($4.99/mo): photo logging (5/day), daily summaries, Garmin & Strava sync, friend challenges Plus ($9.99/mo): adds unlimited photos, voice logging, weekly review charts Free: text logging stays available after the trial — keep your friends list, meal sharing, and Apple Health sync Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period.
