1. The Speed Gap: Seconds Matter When Bolusing
For a person with Type 1 diabetes, counting carbs isn't a leisure hobby—it's a time-sensitive task that happens right before eating. Waiting several seconds for a heavy app to load, dismiss promotional banners, and wait for cloud sync can be exhausting.
12 Carbs opens instantly in under 300 milliseconds. The search field is immediately active, or you can tap the camera icon to scan a package barcode in a single second.
2. The Free Barcode Scanner: A Public Utility
Over the years, conventional trackers have increasingly moved basic barcode scanning behind recurring paywalls. At 12 Carbs, we believe basic nutritional awareness should be fast and accessible.
We leverage the open, community-powered OpenFoodFacts database (4M+ items worldwide), giving you fast, free barcode lookups without paywall restrictions.
3. Data Sovereignty & Health Privacy
Typical cloud-based health apps require central accounts and store your personal meal logs on remote servers.
12 Carbs does not require you to create an account. We do not ask for your email, we do not build an advertising profile on your dietary choices, and your entire database lives locally on your smartphone. You can back up or export your data anytime in standard format.
4. Respectful, Non-Predatory Monetization
Many people have experienced signing up for a free trial only to forget to cancel and face an unexpected recurring renewal on their payment method.
12 Carbs is fully usable for free supported by non-intrusive native ads integrated seamlessly among the content (no banner popups or interruptions). If you want an ad-free experience, we offer prepaid passes (1, 3, 6, or 12 months) and a Lifetime unlock. Prepaid passes expire cleanly without automatic recurring charges.
