Feature Comparison

CalPerks

Effortless AI-Powered Logging

Forget complicated barcode scanners and endless database searches. With CalPerks, you just describe what you ate in plain language—you can even speak it. For example, say "a large bowl of beef pho with sriracha" or "two chicken cutlets coated in mayo and panko." Our AI understands your context and instantly provides a calorie and macro estimate, turning a task that used to take minutes into one that takes under 30 seconds.

Trusted USDA Nutrition Data

Your estimates are built on a foundation of real science. CalPerks primarily uses data from USDA FoodData Central, which is the gold standard for reliable nutrition and calorie information. This means you get accurate, trustworthy data instead of crowd-sourced guesses. If the USDA doesn't have a specific item, our AI acts as an intelligent fallback to still give you a solid, transparent estimate.

Transparent & Confidence-Based Estimates

We believe you should know how your numbers are calculated. Unlike other apps that just give you a guess, CalPerks clearly shows the source of its data and its confidence level in each estimate. If something in your description is unclear, the AI might ask a simple clarifying question to ensure you get the most accurate breakdown possible, putting you in control.

Motivational Streak Rewards

CalPerks makes consistency rewarding in a very real way. The app is designed to be so easy that sticking to your daily logging streak becomes simple. To celebrate your commitment, we offer a unique perk: track your meals every day for a full year and you'll earn $100. It's a powerful incentive that turns a healthy habit into a rewarding achievement.
