Frequently Asked Questions
Find answers to common questions about Achilles.fit™
What is Achilles.fit™?
Track workouts, plan training, analyze progress. Running, strength, cycling, swimming, and habits in one app.
🚀 Why choose Achilles over other platforms?
You own your data. Export your workouts and habits to CSV, delete your account and everything in it anytime. No lock-in, no hostage situations with your fitness history.
Deep customization. Adjust training volume, paces, equipment, goals, and exercise preferences. Your plan adapts to you, not the other way around.
Full edit capability. Swap exercises, modify workouts, change your schedule. Other apps give you a plan and say "take it or leave it." We say "make it yours."
No expensive device required. Works on any browser, any device. You don't need a $500 watch to train smart.
Real power, simple interface. Four sports (run, strength, bike, swim), habit tracking, progress analytics, AI chat assistance. All without the bloat.
We actually care. No dark patterns, no upsell traps, no "premium tier" holding basic features hostage. Just good software built by athletes who use it themselves.
💵 How much does Achilles cost?
$7/month, or $70/year (two months free). Every plan starts with your first month free - nothing is charged until it ends, and you can cancel anytime.
Cancelling never locks you out of your own history: read access, data export and account deletion stay free forever.
📋 How do I modify my training plan?
Settings that update dynamically (no plan regeneration):
- •Running volume (±2 levels): Workouts scale automatically (e.g., medium → hard scales distances)
- •Running fitness: Training paces recalculate instantly
- •Strength training goal: Rep ranges and rest periods adjust on-the-fly
- •Experience level (±1 level): Exercise count adjusts for strength workouts
- •Equipment: Exercise suggestions update
- •Personal records: Tracking only
- •Race goals: Informational only
Settings that require plan regeneration:
- •Running volume (>2 level jump): e.g., very_easy → extreme
- •Experience level (>1 level jump): e.g., beginner → advanced
- •Runs/lifts per week: Changes workout frequency and split structure
- •Training timeframe: Affects periodization (4/8/12/16 weeks)
- •Primary goal: Running vs strength focus
Access settings via Settings in the navbar. Large changes prompt for confirmation to ensure proper progression.
🏋️ Can I track different types of workouts?
Running, strength, cycling, swimming, and habits. Log workouts by typing them in plain English, or record a run with your phone GPS. Strava import works today; Garmin, Whoop, Oura, COROS and Fitbit are built and waiting on each company to approve our developer access. Apple Watch data will arrive through the iOS app, which has not shipped yet.
✅ What works today, and what does not?
Working today:
- •AI training plans - Multi-week running, strength, cycling, swimming and triathlon blocks built around your schedule, goals and current fitness.
- •AI coach, in chat - Ask for a change, log a session in plain English, or ask why a workout is in your week. It answers with your actual training in front of it.
- •Workout logging - Type "5 mile easy run" or "3x10 squats at 185". Running, strength, cycling, swimming and daily habits.
- •GPS run recording - Record a run from your phone browser - distance, pace, splits, elevation and your route, drawn and saved with the workout. (Keep the screen on while you run; a browser cannot track GPS in the background.)
- •Analysis and records - Personal bests, race-time predictions, recent form, aerobic efficiency, year-on-year mileage, streaks and an activity heatmap.
- •Strava import - Connect Strava and your history comes across, deduplicated against anything you have already logged. (Limited to our first few athletes while Strava reviews the app, and Strava activities are kept out of the AI coach - their API terms do not permit it.)
- •Google Calendar sync - Push your whole training block into the calendar you already look at.
- •Reminders and offline logging - Web push reminders at your local training hour, and workouts logged with no signal that upload when you are back.
- •Export and delete - Everything you have, as JSON or CSV, whenever you want it - and a real delete that takes your third-party tokens with it.
Not yet:
- •iOS app and Apple Watch - A native app with a Watch companion, background GPS, and Apple Health sync so your Watch workouts land here automatically. (Written and not yet released. Apple Health can only be read on the device, so Apple Watch data will always arrive through the app rather than the website.)
- •Garmin, Whoop, Oura and COROS sync - Activity import plus sleep, HRV and recovery from the wearables that publish it. (Built and waiting on the vendors rather than on us. COROS approval is pending; Garmin has closed its developer intake entirely, so nobody can give you a date for that one.)
- •Community features - Challenges, clubs and verified results on top of the leaderboard. (The leaderboard is live today and is opt-in, ranked, and on the honour system.)
📊 How does the analysis feature work?
Workout patterns, progress charts, PRs, and trends. Data-driven insights.
⚙️ What settings can I customize?
Main Settings Hub: Profile (name, timezone), theme, Google Calendar sync, apps & devices, data export, account management. Under apps & devices, Strava can be connected today and the other providers show as coming soon until they approve us; Apple Watch data will arrive through the iOS app rather than the website, because Apple Health can only be read on the device itself.
Running Settings: Training volume (difficulty, runs/week), running fitness & paces, race goals, personal records.
Strength Settings: Lifts per week, equipment availability (gym/home), one-rep maxes.
Habit Settings: Daily habit tracking configuration.
Exercise Settings: Manage exercise library and preferences.
Motivation Settings: Daily motivation style and content preferences.
Cycling Settings: Rides per week, FTP (Functional Threshold Power), cycling goals.
Swimming Settings: Swims per week, CSS (Critical Swim Speed), swimming goals.
🌎 Can I change my timezone?
Timezone is set during onboarding. You can update it in Settings → Profile, but changing your timezone may affect how past workouts and habits are displayed relative to dates. For best results, set your timezone once and avoid changing it mid-plan.
🔒 Is my data secure?
Yes. Your data is encrypted, never sold, and always private. You can export your workouts and habits, and delete everything, at any time - and deleting your account removes your third-party device connections with it.
💾 What data management options do I have?
Export your workouts and habits as CSV, reset your plan, or delete your account. All in Settings. For a copy of anything the CSV export does not cover, email admin@noblerworks.com.
🏁 How do I set up race goals?
Settings → Running. Set distance, date, goal time.
👥 Who built this? And why?
Nobler Works LLC. Tired of over-engineered apps. Simple, athlete-first, built to last.
