XP & avatar.

Everything that earns XP

XP lands the moment you log something, and anything judged on the whole day is settled after midnight. Your streak bonus multiplies everything except badges, Trials, invites and goal bonuses.

Levels and ranks

Each level takes a little more XP than the one before. Level 100 is the top, and it takes 2,184,450 XP in total.

XP needed = 120 + 55 × L^1.5

With steady daily use, level 10 takes about two weeks, level 25 about four months and level 50 around two years.

Your title is your rank plus a Roman numeral for your tier within it. Level 23 is Athlete IV. Each rank brings a new outfit for your avatar.

Streaks and your bonus

You have two streaks, and each one grows a bonus on the XP you earn. Missing one never resets the other.

• Activity streak: days in a row with 3 of the 7 active-day things done.
• Quest streak: days in a row with at least 2 of your 3 daily quests done.

bonus = min(12.5%, 0.25% × activity days) + min(37.5%, 0.75% × quest days)
both streaks together: +1% a day, up to +50% at 50 days

Shields

• Earned: one each time either streak reaches 7, 14, 21 days and so on, and one every 5 levels. You can hold 3.
• Used automatically when a day would break a streak of 3 days or more. If both streaks break and you have one shield, it saves the one worth more bonus.
• A shielded day keeps the streak alive but doesn't add a day. A shield on your activity streak also cancels that day's lost XP.
• A streak of 1 or 2 days can break without costing anything.

Losing XP

Some misses cost XP, so the game means something. Never more than 150 XP a day, never below zero, and never on a shielded day.

Deleting an entry takes back the XP it earned. Your level can drop, but gear from levels is yours to keep.

Daily quests

You get three quests a day: one easy, one medium and one hard. They're picked to cover different things you track, and they stay the same all day. You can swap one quest a day, and finishing all three pays +60.

• Rest days get no workout quests. They lean toward mobility, walking and extra water.
• Fast quests only go to regular fasters (3 fasts of 12 hours or more in 30 days). No food quests while a fast is running.
• New quests arrive at midnight.

Weekly challenges

One challenge a week, Monday to Sunday, picked from things you already track. It pays as soon as you meet it.

Trials

Reaching a new highest level offers a Trial: a timed challenge with secret gear as the prize. You have 24 hours to accept, and skipping costs nothing. One Trial runs at a time.

• Targets come from your own last four weeks. Step Storm, for example, asks for 1.5 × your average steps, rounded to 500, never under your step goal and never over 25,000.
• Workout targets never go past the workouts you have planned, which works out to no more than 6 in 7 days.
• Only Trials for things you log are offered. No Trial asks about weight, eating less or fasting.
• Accept before noon and it starts today, otherwise tomorrow. Each day is judged at noon the next day, so steps and sleep can sync.
• Your first win of a Trial earns its secret gear piece, and your second its gold shiny version. There are 16 secrets in the Vault. Failing costs no XP and doesn't touch your streak.

Badges

68 badges in 12 families, worth 39,920 XP in total. Each one also gives your avatar a piece of gear. Badges that count things you can delete are taken back if the count drops.

Gear

• Rarity: Common, Rare, Epic, Legendary, Mythic. Level gear follows your rank: Common below 20, Rare 20–39, Epic 40–64, Legendary 65–79, Mythic 80–99.
• 13 slots: head, eyes, face, neck, chest, wrists, hand, back, waist, feet, effect, frame and companion.
• In each slot your avatar wears the rarest piece you own, the newest on a tie. In the Locker you can pick any piece you own for each slot, or none.

Your avatar's body

Your avatar is built from your age, height, weight and sex, and your body fat: a reading from the last 60 days, or else the Deurenberg estimate (see Sleep & body). It changes as your weight does.

• Losing weight: about 80% of it comes off as fat (85% on Endurance). The lean share rises slowly with age.
• Building muscle: about 65% of the gain is lean under 30, scaled by how often you've trained in the last 4 weeks. Gaining on other goals is mostly fat.
• Maintain and Endurance: months of training slowly swap fat for muscle.
• With age, more weight sits around the middle and muscle definition fades.

You pick the look: 8 skin tones, 6 eye colours, 7 hair styles for each sex, 10 natural hair colours, 4 dyes that unlock at levels 20, 30, 40 and 50, and a beard for men.

Friends and leagues

• Swap player codes to see each other on your leaderboard: this week, by level, or all time. There are no accounts or servers, and scores update when you swap new codes.
• A code carries your nickname, avatar, level, XP, streak and badge count, never your logs.
• Invites: a friend who joins with your link or code starts with +100 XP. You get +250 when you add their code, for up to 10 friends.
