Sapere.
Your devices record the ride. intervals.icu holds your data. The Sapere family reads it, coaches your day, measures your HRV on your wrist, and rides shotgun on your Garmin — every part feeding one honest daily answer.
Garmin data fields and Apple Health are coming — today the family runs on intervals.icu + Studio.
One system
intervals.icu is the hub everything reads from and writes back to. Studio coaches your day on your phone. Watch measures your HRV on your wrist and shows readiness at a glance, through Studio. Sistema rides your Garmin in three modes — standalone, no phone required. Salita tests your threshold and writes your real W′ back to the hub. Saggio is the engine that runs the daily answer, on-device inside Studio.
Studio
The brain on your phone — coaches your day, powered by Saggio. Reads from intervals.icu.
Sistema
One Garmin Edge data field, three modes: Strada (adaptive, no power meter needed) · Storia (efficiency & durability) · Scorta (live W′-balance battery). Reads from intervals.icu.
Salita
Indoor trainer app — runs threshold tests and writes your tested W′ back to intervals.icu, so Scorta reads a real number.
Saggio
The engine inside Studio — the readiness model that powers the daily answer.
The brain on your phone. Reads your fitness, form and recovery from intervals.icu, runs it through Saggio, and gives you one honest daily answer — go, ease, or rest — with every number behind the decision one tap away.
Ships with Studio on your Apple Watch — a native watch companion, not a separate install. Apple only exposes SDNN from your wrist; Watch reads the raw beat-to-beat signal itself (from Apple's own Breathe recording) and computes the same rMSSD your readiness score is built on. Every reading goes to Studio, which writes it to intervals.icu — Studio sends your latest readiness and recovery trend back to show at a glance on your wrist and watch face.
One data field on your Edge, three lenses for every ride. Reads your zones and power profile from intervals.icu so the numbers on your bar already know who you are.
Run a critical-power test on your indoor trainer. Salita writes your tested W′ back to intervals.icu — so Scorta's battery on the bike reads a real, earned number instead of an estimate. This is the loop that makes the system honest.
A compact data strip that sits next to Garmin’s own map — your key numbers (speed, power, HR, climb) without giving up the map. A data field can’t draw a map, so Striscia complements it instead of replacing it.
You never install Saggio, and it never phones home — it runs entirely on your phone, inside Studio, with no server call. It weights your CTL, ATL, HRV and sleep against your own rolling baseline and produces the daily answer. Marked as an estimate, always.
Strada, Storia and Scorta are modes inside Sistema — not separate installs. Saggio is the engine inside Studio — you never install it separately. Watch ships with Studio on your Apple Watch — nothing extra to set up either.
Sapere is a training & wellness tool — not a medical device.
