LoseStreak

LoseStreak turns fitness into a spectator sport between friends. Challenge someone to a 1v1 battle, open up a free-for-all, or split into teams across 23 challenge types — weight loss, running, push-ups, squats, cycling, steps, HIIT, strength, and more. Raise the stakes with bets. Watch friends battle in a live feed. Cast votes, talk trash, and let a brutally honest AI crown the winner.

HOW IT WORKS

• Challenge a friend, group, or team
• Pick from 23 challenges across weight, cardio, activity, training, bodyweight reps, and composite categories
• Set your stakes — money, tasks, items, or custom bets
• Log daily: weigh in, snap your meals for AI calorie estimates, and let workouts sync automatically from Apple Health
• At the end, the AI delivers The Verdict — a cinematic reveal that crowns the winner and roasts the loser

23 CHALLENGE TYPES Weight, Weight Loss, Running, Cycling, Swimming, Walking, Hiking, Out Train, Steps, Active Minutes, Strength, HIIT, Yoga, Push-Ups, Squats, Lunges, Planks, Burpees, Pull-Ups, Sit-Ups, Jumping Jacks, Calorie Deficit, Triple Crown.

AI FOOD SCANNING Point your camera at any meal. The AI estimates calories, macros, and portion size instantly. Your meals are visible to your opponent — full transparency, no hiding behind "I ate clean this week."

AUTOMATIC WORKOUT TRACKING Workouts sync from Apple Health — Apple Workouts, Strava, Peloton, Nike Run Club, Garmin, and any app that writes to HealthKit. No manual entry. No fabrication.

ON-DEVICE REP COUNTING For push-ups, squats, lunges, planks, burpees, pull-ups, sit-ups, and jumping jacks, reps are counted by your iPhone camera using Apple's Vision framework. Framing is validated before each set. No self-reported numbers. No cheating.

THE VERDICT At the end of each battle, the AI analyzes everything — weight change, calories, workouts, consistency, and progress photos. Results are revealed card by card: The Weigh-In, The Kitchen Audit, The Gym Report, The Glow Up Check, The Consistency Award, and finally — THE VERDICT. Multiplayer verdicts roast every player individually.

LIVE BATTLE FEED Watch your friends' battles unfold in real time. Vote on who you think will win. Talk trash in the comments. Every battle is a spectator sport.

BETTING Put something on the line. Money, push-ups, buying dinner, or a public social media admission of defeat. Honor system — the app tracks who owes what.

BADGES & LEVELS Climb 10 tiers from Rookie to Apex. Earn badges with attitude — Baby's First W, Three-Peat Freak, Built Different, Plot Armor, Certified Psycho, Meal Paparazzi, Gym Rat. Some are stackable.

ONBOARDING THAT MEANS SOMETHING Build your personalized plan, get assigned one of 8 archetypes (Comeback Kid, Aesthetic, Athlete, Spite Lifter, and more), and sign a commitment card before you start. By the time you're competing, you've already earned it.

PRIVACY HealthKit data stays in an encrypted backend (never iCloud, per Apple's rules). Phone numbers are SHA-hashed on-device before friend matching. We don't sell your data. We don't use it for advertising.

This is not a wellness app. This is accountability through competition.
