About this app
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
PARTNER AND CAREGIVER SUPPORT (Premium)
Invite a partner, grandparent, or nanny to log alongside you — for one child or several, with one shared code. Their logs appear in your history, clearly marked.
EXPORT FOR YOUR GP OR MIDWIFE
Export a clear, organised PDF of your diary anytime — perfect for appointments. Free accounts can export up to 45 days at a time; Premium can export your complete history in one PDF.
FREE AND PREMIUM
Free: Manual and voice diary logging, 45 days of history, one free AI Insight ever.
Premium ($8.99/month or $39.99/year): Daily AI Insights for you and every child, unlimited history, unlimited PDF export, photo logging, multiple child profiles, partner and caregiver invites.
Cassi is designed for breastfeeding and formula-feeding mothers, caregivers, and anyone who wants to understand their own gut health. Cassi is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Always consult your healthcare provider about your or your baby's health.
