Free, without scan credits.
Grape is bundled with the app. Download optional Plum on a supported phone. Run these local models as often as you want, without a subscription, monthly quota or per-scan charge.
FREE CALORIE & MACRO TRACKING
Your phone runs the AI.
You don’t pay per scan.
Grape XS and Plum S are two AI models trained by NommAI. Both have open weights on Hugging Face. Both run on your device for unlimited free calorie and macro estimates. No subscription is required.
Available free on the App Store and Google Play.
Your meal stays local.
Analysis happens on your device. Scanning does not send a photo to a hosted AI service. Review the estimate and save it in your local diary. An account is optional for local use.
Research you can read.
The model weights are public under their licenses. Our research paper has been submitted to arXiv and is awaiting publication. We’ll link its methods and evaluation when it is public.
FREE LOCAL MODELS STAY FREE
More model choices.
Always your choice.
We’re developing larger models that we plan to offer through an optional API service. They would run on our servers and have separate pricing and data-sharing terms.
You won’t need them to keep using your free on-device models. Grape and Plum will remain available for unlimited local scans. Optional cloud backup and other hosted services are separate from that commitment.
API models are planned, not available in this release. A bigger model is not a guarantee of a better estimate for every meal. We’ll publish evaluation details before making accuracy claims.
PUBLIC WEIGHTS · PAPER PENDING
See what runs on your phone.
Grape estimates your whole meal. Plum combines meal-total estimation with a food-by-food list. Their download files and licenses are public, so you can inspect the model releases.
Public weights are not the same as an unrestricted open-source license. Read each model’s license for its permitted uses. The arXiv submission is awaiting publication; this is not a claim of completed peer review.
What free means here.
Is there a daily limit on free scans?
No app-imposed scan credits or monthly quota apply to Grape and Plum running on your phone. Processing speed depends on your device. Plum is an optional download of about 1.04 GB and can take several minutes on slower Android phones.
Will I need a subscription later?
No subscription is required for the on-device models. Larger hosted models and optional cloud services are planned separately, and using them will be your choice.
Can I use the calorie tracker offline?
Installed models analyze photos locally. Initial notice acceptance, model downloads and later required policy updates need internet. You can read your existing local diary offline.
Does free mean my photos train your models?
No. Scanning does not automatically upload or contribute photos. Any model-improvement contribution requires a separate choice. Our privacy policy explains installation records, accounts and optional services.
Are the calorie estimates exact?
No. Portions, oils, sauces and hidden ingredients can change the result. Review and correct your estimates. These tools are for general food tracking, not medical decisions.
