Can I choose which allergens and additives to check?
Yes. Browse the allergy-related, dietary, preservative and additive presets, see what each contains, then refine your selection. Arista Reader checks your selected ingredient names and available aliases together. Matches depend on label clarity and catalogue coverage.
Does it work without a connection?
Yes. The ingredient catalogue is included with the app, and recognition and matching run on your device. A connection is needed for catalogue updates, optional account sync and App Store purchases.
Do my photos leave my device?
Arista Reader does not upload your camera frames, label photos or saved scans. Choosing to share or export sends a copy to the destination you select. Apple device backups follow your own backup settings.
Which languages can I use?
The app is available in English and Spanish, with regional ingredient names for Spain and Mexico. Matching includes available aliases in both languages. Recognition also depends on label clarity and catalogue coverage.
What happens if Pro expires?
Your ingredients, extra profiles and saved scans are retained. Scanning returns to the primary profile, including its selected custom ingredients. Choose one preset plus 10 extra catalogue ingredients to continue scanning for free. Existing pre-change selections keep their coverage. Creating or editing custom ingredients requires Pro.
