Know when to push.
Know when to rest.
Thríamvos reads the training you already log and the recovery signals your body already gives off, and turns them into one number each morning — with the working shown, so you can see how it got there.

Training load
How hard the last week has been, against the base you've actually built (ACWR)
Recovery
Your morning heart-rate signals, judged against your own normal (HRV, resting HR)
Every effort counted
Rides, runs and strength work measured on one scale (TRIMP, sRPE)
One number,
and its reasons
The training you already log and the vitals you already record become a single readiness figure each morning — split into the two halves that made it, so you can judge it for yourself instead of taking it on faith.
Start freeSee your load
before you feel it
Your last week measured against the base you've actually built, so a spike shows up as a number first rather than an injury later.

When it doesn't know,
it says so
Most apps always show you a number. If your history is too thin for one to mean anything, this one shows nothing and tells you why. Every figure that does appear names the formula behind it — and flags when it's leaning on an estimate rather than something you actually measured.
Read the mathLet recovery
lead the way
Your normal is built from your own mornings, over weeks — never from a chart of what an average body is supposed to do.

No new hardware, no extra straps. Connect the accounts you already use and Thríamvos does the rest — quietly, in the background, every day.
How the Apple Health connection works →What's next
Thríamvos is actively evolving. Here's what we're building toward.
Shipped
Provenance on every number
Each figure names the formula behind it, and says when it rests on an estimate rather than something you measured.
Next
Longer history
Twelve months of volume and consistency, rather than the current rolling six-week window.
Exploring
Zone provenance from Strava
Reading your configured zones to show which came from real efforts and which from an age formula.
Simple,
honest pricing
One plan, everything included. Fourteen days free — long enough to actually build a baseline and see a readiness score, rather than just the setup screens.
