Your body creates signals every day
Training, sleep, stress, and movement already generate useful data. Forjum starts from that reality.
App Store & Google Play
Your watch tracks your body.
Forjum turns it into real RPG progress — no fake XP.

How It Works In Action
One flow: your body signals, adaptive decisions, short sessions, and real stat progression.
Five attributes
Stats that mean something
HRV, sleep, VO2Max, workouts, and more — mapped to RPG stats that reflect your actual fitness state.
MIG
Might
Raw physical power and impact — strength training, load, and neuromuscular force.
AGI
Agility
Speed, reactivity, and precise motor control.
VIT
Vitality
Cardiorespiratory endurance and fatigue resistance — VO2Max, cardio load, stamina.
SPI
Spirit
Recovery, autonomic balance, and stress resilience — sleep and HRV-driven readiness.
PRE
Presence
Social influence, engagement, and opportunities — connection, events, and shared activity.
Daily readiness
A recovery score that tells you when to push
Every morning Forjum reads your sleep, HRV and resting heart rate and turns them into a 0–100 recovery score — where 50 means your personal baseline, not a grade. Train hard and it drops: that’s physiology, not punishment. Sleep well and it climbs back.
REC
Recover
Well below your baseline — easy movement and breathing sessions are the play. The hard session can wait.
MOD
Moderate
Slightly under your normal — moderate effort is fine, stop before it feels hard.
PUSH
Push OK
At or above your baseline — green light: a hard session will land well today.
Behind the score, four recovery systems — Cardio, Muscles, Focus and Calm — each measured against your own 30-day baseline. A short-sleep guardrail means the app never tells you to push on five hours of sleep.
Play.
Compete.
Recover.
Sensor-verified play
Every minigame runs on your watch and is verified by its sensors in real time. Balance poses tracked by the accelerometer. Breathing rhythm measured by heart rate. No self-reporting.

Philosophy
Built to make itself unnecessary
Most fitness apps engineer dependency — streaks, daily notifications, guilt mechanics. Forjum does the opposite. After roughly a year of use, you should be able to interpret your body's signals without the app.
We consider it a success if you graduate. The character grows, you grow, and eventually you trust your own biometrics without needing a dashboard to tell you.
No streak mechanics
No streaks, no guilt, no penalty for a missed day. But your stats aren't a score you only climb — they mirror your body. Consistent training builds them; extended inactivity lets them fade, exactly as real fitness does. That's the point: they reflect reality, not attendance.
Adaptive daily guidance
Each morning, the app reads your signals and suggests whether to push hard, go easy, or rest. No fixed schedule.
No XP inflation
Stats only rise when your physiology actually improves, and weekly capacity tests confirm your gains are real. There is no reward for opening the app.
Privacy by architecture
Your health signals are processed entirely on your device. Your biometric data is never transmitted to our servers.
Privacy
Your body.
Your body.
Your data.
All health signals are processed on-device using HealthKit and Wear OS Health Services. Your biometric data is never transmitted to our servers. Forjum contains no ad network and no advertising or tracking SDKs. For app stability and optional online multiplayer we use Firebase (anonymized crash, usage and game-score data only) — see our Privacy Policy.
You can verify this independently via the App Store and Google Play privacy nutrition labels.
On-device only
All biometric computation happens locally on your device. Your health data is never synced to the cloud.
No sign-up required
No email, no password: an anonymous profile is created automatically, and you can optionally link Apple or Google later. Single-player works offline.
No ads. Ever.
Free download. Premium optional. No subscription traps, no in-app ad networks.
Open multiplayer
If you choose to connect online, only your chosen username and game scores leave the device.
