Kalori vs YAZIO: AI Photo Tracking vs Fasting + Recipes
YAZIO is the German nutrition powerhouse with a 100M-user claim, a strong intermittent fasting tracker, and 3,000+ recipes. Kalori is the iPhone-only AI calorie tracker that prioritises speed of logging above everything else. They overlap on calorie counting but diverge on what else they want to be. This page compares pricing, features, privacy, and platform support so you can choose the one that fits.
Choose Kalori if
- • Logging speed matters more than fasting or recipe content
- • You're on iPhone and don't need Android
- • You want a single flat plan instead of pricing tiers
- • You'd rather pay $30/year than $40/year
Choose YAZIO if
- • Intermittent fasting is part of your routine
- • You want guided meal plans and 3,000+ recipes
- • You use Android or want a longer track record
- • Brand maturity (100M users, 12+ years) matters to you
Speed-of-logging vs lifestyle programme
YAZIO, founded in Erfurt, Germany in 2014, has grown into one of the biggest nutrition apps globally. The 100M-user claim is the largest in the comparable category. The product covers calorie tracking, intermittent fasting, water and step tracking, a deep recipe library, and goal-driven plans. The branding leans warm and approachable, with a friendly mascot character.
Kalori, launched in 2025, is narrower on purpose. The whole product is calorie and macro tracking, optimised for the case where you want to know what you ate without spending five minutes on each meal. The camera is the primary input, AI handles identification, and the dashboard stays minimal. There is no fasting tracker, no recipes, no plans.
Both apps sync to Apple Health and let you set calorie targets. The choice is mostly about whether you want a feature-rich nutrition platform with content (YAZIO) or a fast tracker that does one thing well (Kalori).

Privacy & data
YAZIO is operated by YAZIO GmbH, a German company. As an EU-based business, it is subject to GDPR and stores user data on EU infrastructure. The free tier shows in-app upgrade prompts but does not run third-party advertising in the same way US-based competitors do.
Kalori is operated by Sunbranch AS, a Norwegian company. The app shows no advertising at any tier, does not sell user data, and stores meal history in an EU-hosted database (Supabase, AWS Frankfurt). On the privacy axis, Kalori and YAZIO are aligned — both are EU-rooted and conservative with user data.
Platform availability
YAZIO runs on iOS and Android. The mobile experience is the primary surface; web access is limited compared to some competitors. If you use Android, that matters and Kalori cannot match it today.
Kalori is currently iOS-only (iPhone, iOS 16 and newer). There is no Android, web, or Apple Watch app. Apple Health sync covers calories, weight, and macros automatically.
Where YAZIO still wins
Kalori is the smaller of the two, and an honest comparison should acknowledge where YAZIO is genuinely better:
- Intermittent fasting integration. YAZIO's fasting tracker is one of the most polished in the category. If IF is part of your routine, that integration alone may decide it.
- Recipe library. 3,000+ recipes with macros pre-calculated, organised by goal and diet. Kalori has no recipe content at all.
- Cross-platform. Android plus iOS. Kalori is iPhone-only.
- Brand and scale. 100M-user claim, 12+ years, a recognisable mascot. The app feels established in a way newer alternatives can't.
Switching from YAZIO
There is no automated migration tool between the two apps. If you decide to try Kalori, the practical path is:
- Download Kalori from the App Store and start the 3-day free trial.
- Set your weight target and macro split on first launch (takes about 60 seconds).
- Log a few common meals via photo so the system learns your portion norms.
- Cancel your YAZIO PRO subscription before its renewal if you decide to stay on Kalori.
Apple Health is shared between both apps, so weight and step data you've logged through YAZIO will already be visible in Kalori via Health sync — you don't lose your weight history.
Frequently asked questions
Is Kalori cheaper than YAZIO PRO?
Typically yes. Kalori's yearly subscription is $29.99 (about $2.50/month), compared to YAZIO PRO at roughly $39.99/year ($3.33/month). YAZIO runs frequent promotions, so the gap can narrow at certain times of year. Pricing is set per region by the App Store, so your local price may differ.
Does YAZIO have AI photo calorie tracking?
YAZIO has been adding AI food-tracking features as one of several logging methods, but the app's core flow is still search-and-confirm rather than fully camera-first. If AI photo tracking is the main reason you're choosing an app, Kalori leans into it more directly. If you want photo logging plus everything else, YAZIO covers more ground.
Which app is better for intermittent fasting?
YAZIO. Its fasting tracker is mature, well-designed, and integrated tightly with the calorie side of the app. Kalori does not have a fasting tracker. If IF is central to your approach, this comparison ends in YAZIO's favour.
Are both apps EU-based?
Yes. YAZIO is German (YAZIO GmbH, Erfurt); Kalori is Norwegian (Sunbranch AS). Both are subject to GDPR and store user data in the EU. On privacy and data-residency grounds, the two are roughly equivalent — pick on product fit rather than data-protection grounds.
Can I use Kalori on Android?
No. Kalori is currently iOS-only and requires iPhone with iOS 16 or newer. YAZIO works on both iOS and Android, so if you're on Android or might switch, YAZIO is the only option of the two.
Should I switch from YAZIO to Kalori?
If you used YAZIO mostly for the calorie tracker and rarely touched fasting or recipes, the camera-first flow in Kalori will probably feel faster. If you used YAZIO's fasting tracker daily, or built routines around its recipes, Kalori is too narrow — stay where you are.
