HOW WE COMPARE

Not All Fitness Apps Are Equal.

Most fitness apps require an account, share your data with ad partners, and lock you in. Here's what separates THYMOS.

See It In Action.

Six things THYMOS does differently. Tap a tab to switch — or just watch them rotate.

SMART COACHING

Lift Smarter.
Not Just Heavier.

THYMOS reads the RPE and RIR you log during each set and automatically suggests the right weight for your next working set. No guesswork, no spreadsheets — just data-driven progression built into your workflow. Don't want a suggestion? Dismiss it with one tap and enter your own weight.

RPE RIR Auto Weight Suggestion Progressive Overload
READINESS

Prime Every Session.
Scientifically.

Evidence-based warm-up prescriptions, built automatically from your working weight. THYMOS ramps you up with the right loads at the right intensities — so you walk into every working set fully prepared.

Auto Warm-Up Builder Evidence-Based Minimizes Fatigue
PRECISION LOADING

Load Smarter,
Faster.

Enter your target weight and get an instant, balanced plate setup — no mental math, no guesswork, just bar-ready precision. Log what you actually lift by selecting the plates on the bar. The app calculates total load automatically for cleaner tracking.

Plate Calculator Plate-Based Logging Bar-Ready Precision
BODY ANALYSIS

See What
You're Building.

Muscle distribution heatmaps show you exactly which muscles you've trained, how intensely, and what's been neglected. Turn your sessions into a clear map of your training balance — and guide what to push next.

Muscle Heatmap Training Balance 7 / 30 / 90 Day View
PROGRESS TRACKING

Real Data.
Clear Trends.

Trends, estimated 1RM, set volume, and full workout history — all in one place. Measured data stays measured. Estimated data is clearly marked. We never mix the two to make numbers look better than they are.

Estimated 1RM Volume Tracking Long-Term Trends
MIGRATION

Bring Your
History With You.

Import from Strong, Hevy, FitNotes, or Excel — all your previous training data comes with you. And when you want to leave, export everything as CSV or JSON. Your data is always portable. Always yours.

Strong Hevy FitNotes Excel CSV / JSON Export
🔒 DATA PRIVACY

Your fitness data can identify you
among 100 million people in 6 days.
Here's what we do about it.

Workout logs aren't just numbers — they're a biometric fingerprint of your body, habits, and schedule. Most fitness apps treat that data as a product. THYMOS treats it as yours. Everything stays on your device by default. No behavioral tracking. No third-party data sharing. Sensitive fields — like readiness scores and wellness context — never leave your phone, ever.

📱
On-Device First
Your data lives on your device. Cloud backup is optional — your phone always stays in control.
🚫
Zero Tracking
No behavioral analytics, no ad SDKs, no third-party data brokers. Nothing watching you lift.
🔐
Sensitive Data Stays Local
Readiness scores, wellness context, and RPE signals are marked sensitive and never synced to the cloud.
📤
Full Export, Anytime
Export everything as CSV or JSON whenever you want. No lock-in. No asking permission.
PHILOSOPHY

Anti-Bullshit
By Design.

Most fitness apps are built to keep you scrolling. THYMOS is built to get out of your way.

01
No Social Feed
No likes, no followers, no comparison anxiety. Just you and your log.
02
No Gamification
No streaks, no badges, no fake motivation. Your PRs are the reward.
03
No Pushy Tactics
No push notifications begging you to come back. No upsell popups during your workout. We're here when you train, gone when you don't.
04
No Vendor Lock-in
Import your history from Strong, Hevy, or any CSV. Export everything as CSV or JSON, anytime. Your data is always portable.

FROM THE MAKER
I'm building THYMOS because I'm tired of fitness apps that treat your data as their product and your attention as their revenue. As a lifter and a developer, I want a tool that respects both the craft and the person behind it. Just an honest tool for honest training. If we are on the same page, welcome aboard.
