REBIRTH brings workouts, fuel, body trends, and habit consistency together into one unified system. Log your training, monitor macros, and track long-term adaptation without jumping across multiple apps.
Live session tonnage math and automated flags as you lift
Clone frequent meals or parse macros via LLMs
Ordinary Least Squares models filter daily weigh-in noise
Medaled achievement rank system for real execution
When your training, food, and body weight live in isolated silos, consistency feels like an unrewarding second job. You spend more time entering data than understanding whether your plan is actually working.
Heavy/Strong log sets, but leave training volume and PR history disconnected from daily nutrition and recovery.
MyFitnessPal charges recurring subscriptions for tedious manual dropdown searching, leading to tracking fatigue.
Standard scale apps create anxiety by reacting to daily water retention and sodium without trend analysis.
Habit trackers and spreadsheets offer zero psychological payoff for grueling, repetitive adherence.
REBIRTH strips away unnecessary fluff and focuses strictly on the metrics that actually drive physical adaptation.
Log sets, reps, load, and RPE with zero lag. Volume calculations and automated Personal Record (PR) flags give you immediate feedback on whether you achieved progressive overload.
Maintain target calorie and protein balances without spreadsheet dread. Clone frequent meals in one click, save custom meal templates, or use the AI Copilot to format and parse meal macros.
Smooth out daily weigh-in fluctuations using rolling averages and linear trendlines. Understand your true weekly rate of loss or gain and monitor long-term physical trends.
From the gym floor to your evening nutrition check-in, here is how telemetry flows through your profile.
Enter reps, load, and RPE with zero lag. Active session tonnage calculations update live to ensure progressive overload.
Clone frequent meals in 1 tap or describe your food in plain English to generate instant structured JSON macro breakdowns.
Weigh in and let Ordinary Least Squares (OLS) linear regression model your real metabolic trajectory toward target body weight.
Physical consistency converts into Performance XP, unlocking 7 visual Rank Medals and tracking your active daily continuity.
Real actions move your progression forward. Every completed workout, nutrition target, and positive habit adds Performance XP to your profile. The progression system doesn't replace the work—it celebrates it.
“You don't level up by clicking buttons. You level up by completing sets, hitting macro targets, and executing in real life.”
Interact with the controls below to experience how active volume and daily macro progress calculate automatically.
Explore the specialized copilot workflows and analytical simulators built directly into REBIRTH.
No expensive recurring AI subscriptions or tedious database searching. Describe your meal or workout routines in plain text within REBIRTH to generate an optimized prompt. Copy it to your preferred external AI (ChatGPT, Claude, Gemini), then paste the JSON response back. Our client-side parser extracts and maps your data directly into the app.
Understand how different meal compositions impact blood sugar spikes. Our double-exponential pharmacokinetic equation models carbohydrate load, dietary fiber blunting, and enhanced insulin sensitivity following physical training.
Daily weigh-ins fluctuate with water retention, glycogen, and sodium. Inside your Profile Analytics and Vitals pages, REBIRTH computes an Ordinary Least Squares (OLS) linear regression model through your raw weigh-in history to filter out daily noise, calculate your weekly trajectory, and estimate arrival dates.
Everything in REBIRTH is designed to streamline data entry and keep your attention on training and recovery.
Eat the same breakfast or post-workout meal regularly? Re-log it in one tap directly from your recent meal history.
Personal records are calculated in the background as you log your sets, notifying you when you beat past numbers.
Total volume is calculated live during your training session so you can ensure progressive overload.
Build templates for your training splits or import them with the AI Copilot to launch workouts with zero setup.
