About this app

Every milestone, every little moment. LittleStems is a gentle milestone tracker and memory keeper for babies, toddlers and small children - milestones, firsts and the funny things they say, kept together on one timeline that's yours to keep.

A STEM THAT GROWS WITH THEM
Every milestone you log helps a little stem grow, sprout leaves and bloom across four areas: physical, communication, social and cognitive. A calm picture of how they're getting on, never a score.

108 MILESTONES, BIRTH TO FIVE
Drawn from NHS, WHO, CDC and AAP guidance, each with a wide, gentle range - never a deadline. No red flags and no percentages. Pacing preferences can widen the windows for prematurity, developmental delay, physical or motor disability, or vision and hearing differences. Turn on reminders if you'd like a nudge when a new window opens.

ONE TIMELINE FOR THE WHOLE STORY
Milestones, little moments and sayings land together on one timeline, newest first, with their birthdays marked along the way, so a year of small moments reads like the year it really was. Add a photo, a video or a sound clip to any of them. Catching up is easy: log what they did this week and fill in the rest as you remember.

MOMENTS AND SAYINGS
First smile, first steps, first word. "Mingo" for flamingo. Keep the moment and the way they said it, not just the date.

LITTLE ADVENTURES
75 small things to do before they're five - puddle jumps, rock pools, cloud spotting - picked for their age and the season. Tick one off and it becomes a first.

ASK LITTLESTEMS
Wondering whether something is typical? Ask in your own words and get an answer drawn from NHS, CDC and WHO guidance, with its sources. It isn't medical advice, and it will always point you to your health visitor or doctor when that's the right call.

PRIVATE BY DEFAULT
Start without an account, and sign in whenever you want to back up and sync across your devices. Our analytics never see your child's name, your notes or your photos. Export everything, or delete everything, from inside the app.

THEMES AND NIGHT MODE
Eight gentle themes, and a calm night mode for quiet updates after bedtime.

FREE, WITH PREMIUM IF YOU WANT MORE
Free includes one child, every milestone, five memories with photos and sound, 250 MB of backup and three Ask questions a month. Premium adds video to every memory, 5 GB of media storage, unlimited firsts and sayings, all 75 Little adventures, up to five children and unlimited Ask. Choose monthly or annual with a 7-day free trial, or a one-time lifetime purchase.

LittleStems is independent, and is not affiliated with or endorsed by the NHS, WHO, CDC or AAP.
