Free baby tracker

Baby growth tracker for weight, length and family records

Log weight and length measurements beside the rest of your baby timeline, so growth notes, feeds, sleep, nappies and daily handovers stay in one shared family record.

Measurements beside the full baby log

Weight and length logs

Record weight in kg and length in cm from the Luna app when you have a measurement to keep.

Growth chart view

See logged measurements in the same Growth section, with weight and length tabs for family record-keeping.

Daily context

Keep measurements near feeds, sleep, nappies, solids, common allergens, routines and notes.

Shared family timeline

Parents and invited caregivers can use separate logins while keeping one family baby record.

How Luna helps day to day

  • Use Luna as a simple baby growth log when measurements would otherwise sit in paper notes, screenshots or chat threads.
  • Keep growth records together with the daily tracker instead of treating them as a separate spreadsheet.
  • Luna is for organisation and record-keeping, not diagnosis, growth assessment, treatment or medical decisions.

Built for shared family handovers

Luna lets parents and caregivers use separate logins while keeping one shared baby log. That means feeds, sleep, nappies, solids, allergens and notes are easier to hand over without screenshots or memory games.

Safety boundary

Luna is for organisation and record-keeping. It is not a medical device and does not make health decisions, assess allergies, or replace professional care. For symptoms, allergy concerns or treatment questions, use a qualified health professional or urgent care route.

Common questions

Yes. Luna supports weight and length measurement logs as part of the family baby tracker.

Does Luna assess my baby's growth?
