The back room
Pro athletes don't make training decisions alone. Behind every plan there's a back room — coaches, physios, sports scientists — turning body signals into the day's call. Tuwa exists because self-coached athletes don't have one.
Serious athletes, coaching themselves, with no staff behind them
If you train sport skill, strength and conditioning in parallel — hard, and by yourself — nobody is watching the whole picture. No one weighs last night's session against this morning's physiology and tells you what today should actually look like.
The apps don't fill the gap. Recovery wearables hand you a score without knowing your plan. AI coaches will happily train you — on their program, not yours. Planning platforms store your plan and leave the daily decision to you at the worst possible moment.
Every tool either owns your program or refuses to touch it.
The decision layer for the plan you author
You write the program — or bring your coach's. Tuwa reads it whole, fuses it with your physiology — HRV, sleep, resting heart rate, training history — and supports the decisions around it: today's numbers, a go / modify / hold verdict, and where your load is trending over the coming weeks.
It never writes the program. It never makes you chat with it. A verdict, the numbers behind it, and the session you actually meant to do.
Built for self-coached athletes, by one
Tuwa is for athletes who train sport skill and strength in parallel and make every training decision themselves — no coach, no physio, no sports-science support on call.
It is built by one self-coached athlete, for exactly this problem. The founder is the reference user: the first person training on every build.
Five rules the product keeps
- 01
Your plan stays yours
Tuwa modulates the program you authored. It never generates one, and it never quietly rewrites yours.
- 02
Text before color
Zone states are always written out. Color is supplementary — never the message.
- 03
No black boxes
Every verdict comes with the numbers behind it, scored against your own baselines. Same input, same answer — the engine is deterministic.
- 04
Equal-weight choices
Go, modify and hold are presented as equal options. The interface never pressures you toward changing your plan.
- 05
Raw health data never leaves the device
HealthKit access is read-only. Raw HRV, sleep and heart-rate samples stay on your phone — only composite scores sync.
