Comparison

Chiron vs MyFitnessPal

Most people don't quit MyFitnessPal because it's bad. They quit because logging is a chore and nothing on the other side of it feels worth the effort.

What MyFitnessPal is genuinely good at

An enormous food database, barcode scanning, restaurant entries, and well over a decade of refinement. If you want to look up a specific packaged food, it will have it. It also has a free tier, which Chiron does not.

If manual logging works for you, it works. This page isn't going to pretend otherwise.

Where it loses people

Search, select, confirm the portion, repeat — four or five taps per item, several times a day, forever. Most people manage a couple of weeks. The industry knows this; it's why retention curves for tracking apps look the way they do.

And when you do log diligently, what you get back is a number. It doesn't tell you what to have for dinner.

The real difference, in one example

Ask a tracking app what to eat for dinner and it can't answer — it only knows what you typed into it. Chiron holds your meals, your training and your weight trend in the same place, so the answer can be specific: you trained legs this morning, you're 40 g short on protein, and your weight has drifted down all week, so dinner should be the protein one and bigger than you think.

That's not a better database. It's a different product.

Which one you should use

Stay with MyFitnessPal if you like logging, want a free option, or need precise packaged-food data.

Try Chiron if you've abandoned a tracking app before, if your data is scattered across three apps that don't talk to each other, or if you want something that reasons about your week rather than just recording it.

See whether it sticks this time.
