LensCal vs Yazio: AI scanning vs recipes, meal plans, and fasting

Two different products, honestly

Yazio and LensCal are often compared, but they're genuinely solving different problems.

Yazio treats "losing weight" as a structured programme — pick a plan, follow recipes, track fasting windows, log meals against the plan. It's an end-to-end diet-coaching app.

LensCal is a logging tool, not a diet programme. The job is to make logging fast enough that you actually do it every day. What you do with the numbers is up to you (or your coach, or your other app).

If you already know what you want to eat and just need to log it quickly, LensCal wins. If you want the app to tell you what to eat, Yazio wins.

Where Yazio wins

• Recipe library. Yazio has years of curated recipes with full nutritional data, which is a genuinely great resource if you cook regularly.
• Meal plans. Ready-made structured plans for specific goals (weight loss, low-carb, vegetarian) — LensCal doesn't try to replicate this.
• Intermittent fasting tracker. Purpose-built timer and fasting stats integrated into the same app.
• Language coverage. Yazio supports 20+ languages vs. LensCal's 6.

Where LensCal wins

• Speed of logging. Under 15 seconds per meal via AI scan vs. 1–3 minutes of text search. Compounds enormously across a week.
• Homemade and eaten-out meals. Yazio is optimised for "cook the recipe, log the recipe". LensCal works on any plate you can photograph, recipe or not.
• Input flexibility. Camera is primary, but you can also upload a photo from the gallery, type a text description, enter calories manually, or re-log a recent meal in one tap.
• No lock-in to a diet programme. If you just want to track and not be coached, LensCal stays out of the way.

For European users specifically

Both apps were built in Europe and work well here. Yazio has deeper German-market recipe content. LensCal has AI scanning that doesn't depend on any specific country's food database — a photo of a plate works equally well in Berlin, Warsaw, Bucharest, or Istanbul. If you travel within Europe or eat a regionally diverse diet, this matters.

Which should you choose?

Choose Yazio if: you want recipes and meal plans inside your calorie tracker, you practise intermittent fasting, or you want a one-app solution for diet coaching.

Choose LensCal if: you don't want recipes imposed on you, you eat a mix of homemade and eaten-out food, or you want the fastest possible logging experience.

They're not mutually exclusive. Some users log with LensCal and use Yazio's recipe content separately — the apps don't overlap enough to conflict.
