CLOUD SYNC

Your Phone Is the Source of Truth.

THYMOS is built around one principle: your phone holds your data, not a server. The cloud is an optional backup — never a dependency.

📡

Offline-First Architecture

Every feature works without internet. Logging, analytics, warm-up suggestions, plate calculator — all local, all instant.

☁️

Optional Cloud Backup

Cloud sync exists for backup and multi-device use only — never required. Your data never leaves your phone unless you choose to sync it.

🔒

Always Your Device

No server outages that break your workout. No API limits. No "service unavailable." Your data lives on your phone — always available.

OFFLINE FEATURES

Everything Works.
Everywhere.

Warm-up sets, RPE weight suggestions, plate calculator, muscle heatmaps, 1RM tracking — all computed on-device. No cloud calls. No latency. Works just as fast in a basement gym with no signal as it does on WiFi.

100% On-Device No API Calls No Latency

What Breaks When You Lose Signal.

Most fitness apps depend on the cloud for features you expect to always work. Here's what that costs you in the gym.

MyFitnessPal

Can't scan barcodes. Can't search food. Half the app goes dark.

MyFitnessPal's food tracking core requires a live server connection. Without WiFi, you can't scan anything, can't look up foods, and lose most of the features you downloaded the app for. It's a cloud service that happens to have a mobile icon.

Strong & Hevy

Try a new exercise offline — get a blank screen where the form guide should be.

Both apps stream exercise demonstration videos from their servers. If you go offline and try a movement you haven't loaded before, the form guide fails silently. You're mid-workout, no signal, and staring at a placeholder instead of the technique you need.

THYMOS
All exercise images are bundled on your device. No streaming. No "load first" required.

Every form guide, every exercise in the library — stored locally when you install the app. Open any exercise for the first time at zero bars of signal and it's right there. Basement gym, hiking trail, airplane, dead zone — it doesn't matter. THYMOS doesn't ask the internet for permission to show you how to squat.
