Private by design
Personal records stay under the user’s control instead of becoming an advertising asset.
A different way to deliver useful software.
Great apps should earn your trust, not rent your health.
Only The App builds focused products that work privately, avoid recurring fees, and respect the people who buy them.

Our first attempt
A product model built on value
We believe health tools should not be held behind recurring monthly fees. A useful, relevant product should be good enough that people choose to buy it once, recommend it, and help fund its continued upkeep through word of mouth.
Hydration is our first test of whether this approach can work again.
The core philosophy
Respect the customer, make the product excellent, and remove the business incentives that work against privacy and long-term usefulness.
One purchase, no rent
Essential personal tools should not stop being useful because a monthly payment ends.
Quality earns support
Ongoing improvement should be funded by creating a product people trust and recommend.
Data ownership
Export and import tools help users keep their information portable. After all, it is their data.
First product
Hydration – Only the App
