What goes in, must come out.

Cassi makes it easy to log your day and your baby's — your meals, their feeds, sleep, and nappies — all in one simple diary. Speak it, type it, or snap a photo.

WHAT CASSI TRACKS

For you:

Meals and snacks, with ingredient-level detail
Drinks, including caffeine and alcohol
Mood and energy levels
Exercise
Your own digestion (Bristol Stool Scale)

For baby:

Feeds — breast, formula, expressed, mixed
Sleep duration and quality
Nappy changes with stool type
Moments — happy, unsettled, crying, milestones
Solid food meals and ingredients
Events — vaccines, illnesses, visitors, teething

AN OPTIONAL HELPING HAND, NOT A DIAGNOSIS

Want more? With Premium (or a one-off AI Insight), Cassi looks back over your logged diary — your diet alongside your own digestion, or your diet alongside your baby's feeds, sleep, and nappies — and shares gentle observations about patterns worth noticing. Never a diagnosis, never a recommendation to avoid anything — just an extra pair of eyes on your own data.

GROWS WITH YOUR FAMILY

Milk only — tracks how your diet may relate to baby through breast milk
Milk and solids — tracks both your diet and baby's own food
Solids only — tracks baby's food directly against their behaviour
Adult mode — track your own gut health without a baby profile
