Crest of
Fitness.
Every workout, meal, and weigh-in earns XP. Six ranks from Beginner to forever-Mythic, daily quests built around your goals, an Apple Watch companion — all running on a privacy contract that keeps your health data on your phone.
Less dashboard. More character.
Six ranks, no daily decay
Beginner → Bronze → Silver → Gold → Elite → forever-Mythic. Diminishing-returns XP so you can’t farm a single action. Full-screen rank-up celebrations and a shareable certificate. No level decay if you take a quiet week.
Local-first by design
Weight, meals, sleep, heart rate, and HealthKit data never leave your iPhone. No account to create, no email to give. The privacy contract is enforced both in the app and on the server.
Daily quests, not daily guilt
13 built-in quests covering steps, water, sleep, and meals — or build your own with custom rules and rewards. Smart-gated reminders defer when you’ve already logged. Clear all today’s quests for a +50 XP Daily Sweep.
Workouts that count
25 starter plans across strength, cardio, mobility, bodyweight, and yoga, plus a custom builder. Live Activity on the Lock Screen + Dynamic Island. Plate calculator. Reference videos. Sessions survive a crash.
Meals on your terms
Build your own Pantry once, log meals in one tap with slot tags (Breakfast / Lunch / Dinner / Snack). 50 USDA-referenced common foods to seed it. Personalized calorie + protein goals from your own numbers — Mifflin–St Jeor BMR, not a black box.
On every surface
Apple Watch companion with four complications, wrist-led workouts that round-trip to Apple Health, ten Siri shortcuts (“Log 250 ml of water”), and a configurable Home Screen widget. One log, every glance.
Forge your crest.
One log at a time.
A glance is enough.
The Apple Watch companion shows your real crest (Shield, Orb, or Hex — whichever shape you picked) with the cyan-to-violet XP arc, your level, your streak, and today’s tiles for steps, water, XP, and calories.
- Four complications across every modern watch face family — circular, corner, rectangular, inline.
- Wrist-led workouts with live heart rate and active calories. Finishing writes a real workout to Apple Health, which the iPhone imports and credits with XP, quests, streaks, and the rank-up celebration.
- Top three plans from My Plans synced from your iPhone. Tap to start; pause / resume / end with a real haptic.
- Paired-only forever.The watch is a companion — it requires your iPhone running CrestoFit and watchOS 26 or later.
What stays. What leaves. What never moves.
We can list every byte that crosses the network. There aren’t many.
- Every weight, water, sleep, mood, meal, and workout log
- Apple Health reads — steps, heart rate, energy, body mass, sleep, dietary water, workouts
- Your custom workout plans, meal Pantry, and saved meal combos
- Custom quests + reminder schedules
- Meal photos, mood notes, plan notes
- Notifications and quiet-hour preferences
- Squad scoreboard fields only — handle, level, XP, tier, tier label, streak days, and your squad ID
- Two timestamps: when you last opened the app and when you joined a squad
- Anonymous crash reports + app-session events (no IDFA)
- Your email, name, phone, or any contact identifier — we never collect them
- HealthKit values, off device. Ever.
- Meal contents, photos, OCR, or calorie estimates
- Heart rate, sleep stages, HRV, or any clinical detail
- GPS coordinates or precise location
- Apple’s advertising identifier (IDFA)
The seven squad fields are enforced both in the app (a single write path with a field allowlist) and on our server (Firestore Security Rules that reject every other field). Read the full Privacy Policy for the field-by-field breakdown.
