Who makes it
Shindo is made by Aleksandr Kolesnikov, an independent developer based in Limassol, Cyprus. One person, no funding, no team, no investors. It is listed on the App Store as Shindo Endurance Training — the bare name was already taken by an unrelated app — and was released on 2026-08-28.
The registered operator for legal purposes is Aleksandr Kolesnikov, Dimitri Nikolaou 7, Limassol, Cyprus, 4006. That detail matters mainly to the Terms and the Privacy Policy, which name a real person with a real address rather than a shell.
Why it exists
Endurance athletes now generate more data than at any point in history, and are arguably worse at deciding what to do with it. The watch reports a readiness score. Another app reports fitness and fatigue. A third has the training plan, written in a week that has since stopped resembling your life. None of them talk to each other, and the athlete is left doing the integration — usually badly, usually at six in the morning.
Shindo exists to collapse that into one answer: what should I do today, and why. And to keep answering it honestly when the week goes wrong, which is most weeks.
The one rule
There is a language model in Shindo, and it is deliberately kept away from arithmetic.
Every number — readiness, training stress, fitness, fatigue, form, calorie and macro targets, thresholds, forecasts — is produced by a deterministic algorithm on your iPhone before any text is generated. The model receives finished numbers and writes sentences about them. Where its wording disagrees with a computed value, the computed value is written over it automatically, and a sentence containing a number that came from nowhere is dropped rather than shown.
This is not a stylistic preference. A coaching app whose numbers might be invented is worse than useless, because it is confidently wrong in a domain where people get hurt. There is one deliberate exception — the weekly plan, where the model may propose a week that a validator then accepts or rejects against limits computed from your own data — and it is documented in full on the methodology page rather than hidden.
What we are deliberately not building
- A social network. No feed, no followers, no leaderboard, no kudos. There is a good app for that and it is not this one.
- An account system. No sign-up, no cloud profile of your training. Your data is on your device, which is also why there is no web version.
- A coaching marketplace. Shindo has no coach-facing surface and will not get one. If you have a coach, use the platform your coach uses — the comparison says so plainly.
- A medical product. Every score is an estimate from wearable data. It does not diagnose anything, and it is not going to try.
- An Android version. Not soon, and possibly not ever. The app is built on Apple Health.
How it makes money
One optional subscription, bought in the app. That is the entire business model. There are no ads, no sponsored content, no affiliate links — including on the comparison pages, which name competitors and earn nothing from doing so — and your data is never sold, shared or used to train anything.
The free tier is not a demo. Readiness and its drivers, today's session, the weekly plan, the fitness and fatigue charts, full workout detail, manual food logging, all eight widgets and all three Live Activity modes are free, for your most recent 60 days. What you pay for is the AI interpretation, the forward-looking models and unlimited history.
Being a one-person operation has an obvious downside — there is no support team, and replies take a day or two — and one real upside: nobody has to be persuaded that shipping an honest comparison page is a good idea.
