Where Cronometer is the better choice
- Barcode scanning, and it is included in the free Basic plan.
- A free Basic plan with custom macro and micronutrient targets, so you can track without paying.
- A food database it describes as over 1 million lab-analyzed or verified foods.
- A listed price below Sunn’s, monthly and yearly.
Where Sunn fits
Sunn is for people who quit tracking because logging felt like homework. You send a photo or type what you ate, and the reply comes back in the same chat. If a portion is off, you correct it by replying.
It also sends an evening summary on days you log and a weekly review. Photo estimates are approximate, and there is no barcode scanner. How a WhatsApp tracker works, and where it falls short →

Is Sunn an alternative to Cronometer?
For tracking calories and macros, yes, with a different shape. Cronometer is a food and nutrient tracking app with a free Basic plan and a paid Gold plan. Sunn works inside WhatsApp, so there is no separate app to open. It has no barcode scanner. If you eat mostly packaged food and want label-exact numbers, Cronometer is the better fit.
Is Sunn cheaper than Cronometer?
Not on the listed prices. Cronometer: Gold listed at $10.99 a month, or $59.99 a year billed annually. Sunn: $14.99 a month, or $79.99 a year. Prices change and vary by country, so check both before deciding.
Can I use both?
Yes. Some people use a database app when they need label-exact numbers and a chat tracker for the everyday habit. Nothing about Sunn stops you from keeping another app.
