It does not name a brand or push one tool over another. It walks you through choosing between what you already have and using it steadily, since parents get on with different tools.

Instantly. The download link appears right after checkout, so you can open it the same day you buy it.

It is built around newborn nails, which are soft and very small, so that is where it fits best. Older babies move differently and the timing part will matter less to you.

Phone, tablet or laptop — it opens on any of them. Nothing to install and no account to create.
