Honest comparison
Why not just ChatGPT & Co?
General AI is genuinely brilliant, and tracking apps are genuinely thorough. Neither was built to be your health companion, though: a coach that knows your numbers, turns your words into real data, and keeps it all private on your device. Here is the honest, side-by-side picture: where each one shines, and where only Kata puts the whole thing together. A grey mark means it is possible, just not on its own.
