Calorie Devil is built around speed, simplicity, and zero fluff. No ads, no recurring subscriptions, and no bloated menus—just a straightforward tool to track your daily food and hit your targets.
This started as a personal project because I got tired of calorie trackers that were slow, clunky, or locked behind pricey monthly paywalls.
Smart Cals (AI Lookup)
Type in almost any meal—whether it's home-cooked, from a restaurant, or bought off the shelf—and get an instant, reliable calorie and macro estimate. Instead of forcing you through bloated public databases filled with duplicate entries, the app taps directly into AI for fast calculations.
Fair, Pay-As-You-Go Credits (No Monthly Fees)
Calorie Devil includes 100 Smart Cals lookups right out of the box with your one-time purchase. Because running AI queries incurs third-party server costs with every lookup, heavy users can top up credits whenever needed (£0.99 for 100 searches). There are no forced subscriptions or hidden tiers—you only pay for what you actually use.
Prefer to track manually or stick to your own saved foods? Every other feature in the app remains completely free and unlimited for life.
Clean Personal Food Library
Add your go-to meals and custom ingredients in seconds. Your food library builds automatically as you log, giving you an uncluttered, personal database of the foods you actually eat without irrelevant search bloat.
Clear Daily Balance & Trends
See your exact remaining calories at a glance, alongside easy weight tracking and rolling history. Look at your calorie balance across the whole week rather than stressing over a single day.
100% Private & On-Device
Your data stays entirely on your phone. No mandatory accounts, no logins, no third-party tracking, and zero advertising.
