Forjum

Your watch tracks your body. Forjum turns it into RPG progress that grows with you.

Five stats from HRV, sleep and training on your phone and smartwatch. Your character grows only when your body does, and within about a year you can read your own signals.

Stats that mean something

Real biometrics, real physiology. HRV, sleep, VO2Max, workouts and more, mapped to RPG stats that reflect your actual fitness state.

Might stat screen: level, weekly sessions and trend chart

Spirit stat screen with HRV, sleep and resting heart rate

Might
Raw physical power and impact: strength training, load and neuromuscular force.
Agility
Speed, reactivity and precise motor control.
Vitality
Cardiorespiratory endurance and fatigue resistance: VO2Max, cardio load, stamina.
Spirit
Recovery, autonomic balance and stress resilience: sleep and HRV-driven readiness.
Presence
Social influence, engagement and opportunities: connection, events and shared activity, down to duels that speak your regional dialect.

A readiness score that tells you when to push

Every morning Forjum reads last night's sleep, the HRV measured while you slept, your resting heart rate and your recent training load, and turns them into a 0–100 readiness score, where 50 is your personal normal. After hard training it dips while your body adapts, and it rises as you sleep and recover.

Forjum readiness card: 45 out of 100 in the Moderate zone. Muscles still tired from recent training and a short night of 6 hours 19 minutes, with the advice to keep effort moderate, and bars for Muscles, Focus, Cardio and Calm

Recover	Well below your baseline: easy movement and breathing sessions are the play. The hard session can wait.
Moderate	Slightly under your normal: moderate effort is fine, stop before it feels hard.
Push OK	At or above your baseline: green light, a hard session will land well today.

Behind the score, four systems mirror your stats: Muscles for strength, Focus for speed and reactions, Cardio for endurance and Calm for recovery and stress. Each follows its own physiology: muscles recover over 48–72 hours after heavy strength work, a short night slows your reactions, and your night HRV is compared with your own previous nights. The card always tells you why the score moved.

How it works in action

One flow: your body signals, adaptive decisions, short sessions and real stat progression.

From your body to the app

Training, sleep, stress, and movement already generate useful data. Forjum starts from that reality.

Four everyday moments tracked by a smartwatch: strength training with a Wear OS watch, cycling with an Apple Watch, a stressful moment at the desk, and a night's sleep logged on a Wear OS watch

Your watch records heart rate, HRV, sleep and workouts; your phone adds steps and movement through the day. More than 14 signals are read through HealthKit or Wear OS Health Services, on your device: connecting your watch takes about 30 seconds, and the import then runs in the background.

The right next step for today, and why it fits you

Forjum suggests what helps now: push, recover, balance, and more. You choose whether to act.

Turn guidance into action

Start a short balance session matched to your state. Your watch tracks stability while you hold the pose.

Progress appears in your 5 stats

Might, Agility, Vitality, Spirit, and Presence update from what you actually do.

Each stat carries the sessions and the recovery behind it, and weekly capacity tests confirm the gains, so the numbers stay tied to your body.

Play. Compete. Recover.

Sensor-verified play. Minigames read your watch or phone sensors in real time: stability through the accelerometer, breathing through heart rate.

Compete without compromising. Duel friends or co-op with others on shared minigame challenges. Only names and scores are ever shared online. Your health data never leaves your device. Multiplayer accounts are optional.

Duels
Async head-to-head: same minigame, scores compared. Presence duels can even speak your own dialect, more than 130 across Italy, Germany, Switzerland and Austria, unlocked after five Presence duels.
Co-op
Team up on a shared challenge against one of the five Guardians, one for each stat.
Mutual help
When a stat reaches zero your character falls into a coma, and if several do, it dies. Other players can send a Healing Potion or a Resurrection Scroll to bring you back.

Core features are free. Supporter (€1.99/month) adds online duels and co-op every 24 hours and two weeks of stat history. Premium (€4.99/month) makes duels and co-op unlimited and adds a 12-month trend for every stat, live metrics during your activities and the regional dialects.
