Head-to-head against the trackers people actually switch from. Real pricing, real trade-offs, and an honest account of where the other app is the better choice.
What Kcalm is
An AI calorie tracker you can use from an iPhone app, by asking Siri, or by messaging a bot on Telegram or WhatsApp. Photo, voice or a plain sentence in, calories, macros and 42 nutrients out. It also logs exercise and GLP-1 shots.
What it costs
15 AI analyses free with no credit card, and a 3-day trial on the chat bots. Premium is USD 14.99/mo or 69.99/yr through Apple, which works out to about USD 5.83 a month on the annual plan. No ads at any tier.
What it is not
There is no Android app and no web tracker, though the Telegram and WhatsApp bots work on any phone. There is no barcode scanner. Kcalm tracks 42 nutrients, well short of the 92 a lab-sourced tool like Cronometer covers, and there is no social feed or community.
