Comparison
Pyrra keeps a live pantry of what you actually own, gives you AI recipes based on those ingredients, and tracks your nutrition from your real food — all on your device. Choose Pyrra if you want a private pantry that turns into recipes with nutrition baked in; choose Cronometer if your priority is the deepest possible micronutrient logging and a long track record.

Pyrra's logs, body profile, and health data stay on your device and sync only through your own iCloud account. They never reach Pyrra's servers, are never sold, and there are no ads on any tier.
Cronometer is cloud-based and requires an account, syncing data across its web and mobile apps. Its privacy policy pledges to never sell personal data to third parties and claims HIPAA, GDPR, and CCPA compliance with data export and deletion available. It does disclose limited, non-PHI data to ad-network service providers to serve targeted ads to free users, and reserves the right to share aggregated, anonymized data. The free tier is ad-supported; Gold ($10.99/mo or $59.99/yr) is ad-free.
Pyrra gives you AI-generated recipes based on the ingredients already in your pantry, with macros calculated from your real ingredients rather than guessed.
Cronometer's recipe tools are a manual "Custom Recipe" builder, where you add individual ingredients yourself and Cronometer computes the combined macro and micronutrient breakdown, plus a Gold-only "Recipe Importer" that pulls ingredients from a pasted URL. Neither generates a new recipe from the ingredients you actually have on hand.
Pyrra keeps a live pantry of what you actually own, including stock quantities and expiry, and that pantry is the direct input to its AI recipe generation.
Cronometer has no feature to track physical food owned at home. Users have requested a My Pantry option on Cronometer's own forums, which confirms the feature does not exist.
Pyrra tracks 70+ nutrients per item, including 13 vitamins, 12 minerals, 6 carotenoids, 9 fat subtypes, and 18 amino acids, sourced from USDA and Open Food Facts.
Cronometer is built around micronutrient depth, and this is where it leads. Its own pages cite different totals in different places, from "up to 84 nutrients" on its Gold and pricing pages to "95+ vitamins and minerals" on its App Store listing; using the more conservative pricing-page figure, Cronometer tracks roughly 82 to 84 nutrients. That full nutrient set is available on Cronometer's free tier, not gated behind Gold.
Pyrra is free to use, with an optional premium tier, and generating recipes is free.
Cronometer's free tier includes ad-supported access to its full nutrient set, free barcode scanning, custom recipes, and 7-day reports. Gold is $10.99/mo or $59.99/yr and adds photo and voice logging, the recipe importer, a fasting timer, unlimited history, and an ad-free experience. A separate Pro tier for professionals is $39.99/mo for up to 10 client seats.
Choose Cronometer if your priority is the deepest possible micronutrient logging. Its free tier already includes a full nutrient set, roughly 82 to 84 nutrients on its own conservative pricing-page figure, plus free barcode scanning, something many competitors gate behind a paid tier. It also has the broadest platform reach in this comparison: iOS, iPadOS, Android, web, macOS, watchOS, and visionOS, with integrations across Fitbit, Garmin, Withings, Oura, Dexcom, Google Health Connect, and Samsung Health. If you want an established, professional-grade nutrition tracker with two-way Apple Health sync and a long track record, Cronometer is a strong choice.
Choose Pyrra if you want a private, on-device app built around a live pantry: it tracks what you actually own, gives you AI recipes based on those ingredients, and calculates macros from your real food rather than manual entry. Pyrra's 70+ tracked nutrients cover the essentials at no cost, with no ads and no data sold. Pyrra is iPhone-only today (iOS 26+), currently in TestFlight ahead of an App Store release.
