The AI coach with a personality you choose — friendly, drill-sergeant, or full-on savage. Science-backed plan. Photo calorie logging. A coach that remembers you.
Trackers count calories. LossBoss coaches you.
LossBoss is an AI weight-loss coach that learns your food preferences, your schedule, and your struggles — then adapts your plan so it actually fits your life. And you pick the personality doing the coaching.
PICK YOUR COACH
- Sunny: warm and encouraging, celebrates every win
- Sarge: direct, no-nonsense accountability
- Savage: opt-in trash talk that roasts your excuses and gets you off the couch (it targets your couch time, never your body)
- Doc: a calm scientist who explains the why behind every number
Each personality even writes its own reminders — weigh-in nudges, meal check-ins, and workout calls in your coach's voice.
A COACH THAT REMEMBERS
Tell it you hate salmon, work night shifts, or always crash at 9pm — it remembers, adapts your meals and plan, and brings the right advice at the right moment. You can view, edit, or delete everything it knows about you in Settings.
SNAP A PHOTO, GET THE CALORIES
Point your camera at your plate and AI estimates calories and protein. Edit in one tap. Or just describe the meal in plain words. Logging without the database spelunking.
SCIENCE-BACKED, WITH RECEIPTS
Your plan is built on the research: Mifflin-St Jeor metabolism math, a safe calorie deficit per clinical obesity guidelines, protein targets that protect muscle, 7,000-step goals from 2025 dose-response data, and weekly adaptive recalibration from your real weight trend. The Learn tab links every claim to the actual study.
WORKOUTS FOR YOUR LIFE
Gym, home, walking, or running plans — with a full routine runner: exercises, sets, reps, rest timer, and check-offs as you go.
GOALS AND REAL PROGRESS
Weekly goals, streaks, a smoothed weight trend line (never panic over one day's number again), calorie adherence charts, and projected goal dates.
YOUR DATA STAYS YOURS
No account. No login. Your profile, logs, chats, and coach memory live on your phone. Chat context is sent to the AI only to generate replies — never stored on our servers.
LossBoss Pro subscription unlocks unlimited AI coaching, photo calorie estimates, daily meal plans, and adaptive recalibration. 7 days free, then $14.99/month or $69.99/year. Cancel anytime.
LossBoss provides general wellness information, not medical advice. Consult your doctor before starting any weight-loss program.
The scale isn't going to scare itself. Download LossBoss and meet your coach.
