Where Cronometer wins
Cronometer is known for lab-verified micronutrient data. It scans barcodes and photos, which Silent does not. It runs on iOS and Android and Web, and Silent is iPhone only. If you share a food log with a partner on Android, or you would rather point a camera than type, Cronometer is the more convenient tool and the subscription is the price of that convenience.
Where Silent wins
Cost and privacy. Silent is $3.99 once, which is less than a month of Cronometer, and it never renews. There is no account, so there is nothing to leak. The AI coach runs on the phone with Apple Intelligence, so your meals and weight are never sent anywhere. It also does two things Cronometer does not: a habit tracker with streaks, and a fasting timer that lives on the lock screen as a Live Activity.
Which should you pick?
Pick Cronometer if you need Android or the web, or if barcode and photo logging are how you stay consistent. Pick Silent if you have an iPhone, you are fine typing what you ate, and you are done paying every year for a food log. Most people who switch say the second part was the whole reason.
