Everything Happy Assistant does

An AI assistant that remembers your context — Happy Assistant remembers your family, pets, work, tastes and dietary restrictions so you never have to repeat yourself.
Food tracking: analyze a meal and follow your nutritional needs — Photograph your plate: the assistant estimates calories and macros, keeps your food journal and compares your intake with needs computed from your own profile.
Workout tracking: every session logged, progress visible — Log strength, running, cycling or swimming sessions by voice or photo, set a sport goal and get a flexible weekly plan that adapts to the sessions you actually do.
Sport goals: a training plan that adapts to your week — Set a goal (half marathon, getting back in shape, strength progress): Happy Assistant suggests a flexible weekly plan that adapts to the sessions you actually do.
A calendar you control by voice — Create, move and view your appointments by voice. Day, week, month and year views, multi-day events and Happy Family sync.
Recurring tasks and reminders that fit real life — Create tasks, deadlines and recurring reminders — every other Thursday, every month — with an adjustable reminder time for each task.
Turning your inbox into concrete actions — Connect Gmail or Outlook via IMAP: the AI spots urgent messages and automatically suggests the appointments and tasks hidden in your emails.

You stay in control: sensitive identifiers are masked before transmission — Happy Assistant masks sensitive identifiers before they reach the model, keeps your memory in the app, and doesn't feed any AI training.
