Where MacroFactor wins
MacroFactor is known for an adaptive algorithm that re-estimates your expenditure from your weigh-ins. It scans barcodes and photos, which Silent does not. It runs on iOS and Android, 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, MacroFactor 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 MacroFactor, 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 MacroFactor 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 MacroFactor 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.
