Annonia is web-based practice management software for registered dietitians and nutritionists. It brings together client records (intake questionnaire, anthropometric measurements and progress charts), personalised meal plans created with AI assistance and adjusted by the professional, a food database with macro- and micronutrients, recipes, shopping lists, appointment scheduling with Google Calendar sync, and a client portal where each client can view their plan and log their progress. It generates PDF meal plans with the practice's logo and colours. Annonia is built for private practices, clinics and universities. Data is hosted in the European Union and processed in line with the GDPR. It is free, with all features, during its launch in Spain.
