YAZIO: AI Calorie Tracker

What it does

YAZIO is a comprehensive health and nutrition app designed to help users track their food intake and manage their weight goals. It functions as a detailed calorie counter, a meal planner with a vast recipe database, and an intermittent fasting tracker. The app personalizes daily calorie and macronutrient targets based on user goals, activity levels, and personal data, aiming to provide a structured yet flexible path to a healthier lifestyle.

Where it shines

YAZIO's onboarding is a masterclass in building user investment. Instead of a quick setup, it employs a lengthy, detailed quiz (00:20-04:11) that explores not just goals but also past struggles and motivations, making the user feel deeply understood. A particularly clever interaction at 00:49 asks users to "tap and hold" to commit to their journey, a physical gesture that creates a stronger sense of buy-in. The app's monetization strategy is also noteworthy, using a gamified spin-the-wheel offer (05:08) to re-engage users who initially skip the subscription, turning a potential exit into a fun, rewarding moment.

UX highlights

Smart Food Logging: After logging a few items (06:21, 06:29), the app begins to recognize patterns and suggests them as a combined "Breakfast" meal (06:40), streamlining future entries.
Playful Feedback: Adding a healthy item like a banana triggers a small "Vitamin Boost!" animation (06:21), offering positive reinforcement for good choices.
Contextual Permissions: The app asks for camera access only when the user first tries to use the barcode scanner (07:23), explaining the feature's value at the exact moment of need.
Comprehensive Creation Tools: Users aren't limited to the existing database. The app provides robust tools for creating custom food items with detailed nutritional info (08:08) and custom meals by combining existing foods (06:48).
Layered Information: The main dashboard (06:08) presents a clean, high-level summary. Users can tap "Details" (11:57) to see a much more granular breakdown, catering to both casual and power users.
Clear Paywalling: Premium features are consistently marked with a "PRO" badge (12:00), so users always know what is included in the free version versus the paid one.

Monetization & growth

YAZIO's primary monetization strategy is a freemium model with a PRO subscription. The first paywall appears at the end of the long onboarding quiz (04:48), presenting the personalized plan as the core value unlock. For users who close this initial offer, YAZIO deploys a gamified spin-the-wheel discount (05:05), creating a second, more engaging opportunity to convert. The main dashboard also features a persistent special offer banner with a countdown timer (06:08) to create urgency. Throughout the app, features like detailed nutritional analysis and advanced recipe filtering are locked behind PRO badges, serving as continuous upsell prompts.

Who it’s for

The app is designed for individuals serious about making a change to their diet and lifestyle, whether for weight loss, muscle gain, or general health improvement. The detailed onboarding suggests a target audience that is willing to invest time to get a tailored experience, rather than casual users looking for a simple tracker. Its features cater to both beginners who need guidance (recipes, meal plans) and experienced trackers who want granular control (custom food entry, detailed analytics).

Notes & opportunities

The onboarding flow is incredibly long, which could lead to high drop-off rates for users with lower initial motivation. While effective for building investment, testing a shorter, more streamlined version could be valuable. The app also asks for a rating very early in the user journey (02:55), before the user has experienced the core food tracking functionality, which might be premature. Finally, the sheer number of features can be overwhelming; a guided tour of the main dashboard upon first arrival could help orient new users more effectively.
