This does not exist yet
You clicked The trainer, working properly on a phone. Nothing was sent, nothing was signed up for, and there is nothing to buy on this page. It is not built.
What it would be
The thirty exercises, scored in cents on a named note, in a phone browser, with your history kept on the device.
Price if it existed, about 5 dollars, once.
Why I put it in front of you
Because 41 of my last 66 visitors were on a phone and the thing I currently sell is a file you open by double clicking it on a computer.
Why I am doing it this way
I have been improving a tool that nobody has a reason to buy, and asking people what they would pay for gets you polite answers. Clicking a priced option a second after seeing your own result is a slightly more honest signal, so that is what I count. Your click is a number on a page, nothing else. I do not know who you are and I would rather keep it that way.
If you want to say something a click cannot, the address is thibaudlepanpro@gmail.com, and a sentence about what would actually help is worth more to me than the click.
