What we won't do
A list of values is only worth anything if it says no to something specific. These are the things we rule out in advance, even when they work commercially — and why.
There will be no ads
A useful ad needs to know who you are, and that requires tracking. It's the door everything else comes through: identifiers, profiles, third parties. Closing it completely is simpler than managing it.
Data is not sold
Not aggregated, not "anonymised", not in exchange for a feature. What you train or what you study is not an asset to monetise.
Your data is not a hostage
Logging and exporting are always free. Charging you to store your own history, or to take it with you, would mean using your work as leverage.
No guilt streaks, no anxious notifications
Streaks can be frozen and reminders respect quiet hours. A health product that makes you feel bad so you come back is broken, however good its retention looks.
Nothing is claimed without a source
Every meaningful recommendation carries its reference and certainty level. If something rests on one small study, we say so — it isn't presented like a systematic review.
Numbers are not invented
When there isn't enough data to score something, it isn't scored. An index with decimals built on a single signal looks like science and is decoration.
From subscriptions, when the time comes
Today both apps are entirely free. The plan is an optional subscription covering what genuinely costs money — the AI we pay for, the advanced analysis, the generators — leaving free the parts that make the product work.
| Never behind a paywall | May become paid |
|---|---|
| Training properly: progression, deloads and calendar | Projections, correlations and downloadable reports |
| Logging your data, unlimited and account-free | Automatic generators (weekly menu, plans) |
| The educational content: guides, glossary and references | AI included without having to get your own key |
| AI using your own key: unlimited and free | Advanced periodisation and adaptive volume |
Being usable is not an extra
- Adjustable contrast and text size, and respect for the system theme preference.
- Everything keyboard-navigable and correctly announced by screen readers.
- Animations switch themselves off if your system asks for reduced motion.
- Language adapts to your level: jargon is explained until it no longer needs to be.
- Neutral Latin American Spanish alongside English, with search that understands regional variants.
