The tracking day starts at 19:00
Not at midnight. So a 2 a.m. feed and a dawn wake-up land on the right day instead of being cut at 00:00.
Nighttime Hours 19:00 - 07:00

Not just a dot
on paper.
Every weigh-in goes straight onto the official growth curves, with its z-score and a reading of nutritional status. You know what it means without waiting for the next posyandu visit.
- z-score
- Calculated automatically from the LMS tables, with the nutritional status.
- WHO and CDC
- Two standards, switchable at any time on the same screen.
- Genetic height potential
- Estimated from both parents' heights and marked on the curve.
Cil grows up,
and so does your little one.
Seven development stages from birth to three years. In the app, each stage explains what usually appears, how to support it and when to be watchful.
-
0-3 months
Meeting the world through faces and voices
Reflexes turn into intentional movement, and the first social smile appears.
Read the stage for 0-3 months -
3-6 months
Rolling, reaching and laughing
Head control is solid, hands discover toys, and the first loud laugh fills the house.
Read the stage for 3-6 months -
6-9 months
Sitting, crawling and almost-words
The world changes once a baby can sit alone and move. Babble starts to sound like words.
Read the stage for 6-9 months -
9-12 months
Standing, pointing and "mama"
Approaching the first birthday: first steps are being rehearsed, and the index finger becomes a communication tool.
Read the stage for 9-12 months -
12-18 months
Walking, words and a will of their own
The toddler emerges: walking alone, naming things, and starting to say "no".
Read the stage for 12-18 months -
18 months - 2 years
Two words, running and pretend play
The vocabulary explosion begins. Two-word sentences and pretend play mark a leap in thinking.
Read the stage for 18 months - 2 years -
2 years - 3 years 1 month
Sentences, friends and "why?"
The two-year-old becomes a talker, a runner and a small thinker, with emotions still learning to be managed.

laid out from the day they are born.

Work out your little one's immunisation dates
Enter their birth date and the next doses appear with their recommended dates. Everything is calculated on your device; nothing is sent.
Pick a birth date, and the next doses appear here.
This calculator runs on JavaScript in the browser. The schedule by age is summarised above.
Consult your doctor. This is IDAI's general 2023 recommendation, and your paediatrician may adjust it. Influenza repeats every year and typhoid every 3 years; those repeats are not counted one by one here.

What keeps it going past the first month.
One log,
the whole family
Mums, dads and caregivers write to the same log. Changes appear instantly on every device, and every entry keeps who made it.
Keeps working without signal
Entries you make offline are stored on the device, then sent by themselves once the connection returns.
If two people change the same entry, the app asks which version you keep. Nothing is silently overwritten.
Pregnancy records are yours alone
Pregnancy and postpartum records are never visible to other caregivers. The rule is kept on the server, not merely hidden on screen.

Questions we often get
Not answered here? Visit the support centre or email support@jejaksikecil.com.
Is JejakSiKecil free?
Yes. Every kind of log, every child, the growth charts, the immunisation schedule, milestones and the content are free. Plus adds full history, 30- and 90-day trends, data export, PDFs, unlimited photos and unlimited caregivers.
Can I use it with my partner or a caregiver?
Yes. Invite them by email, and everyone in that family can read and write the same log. Every entry shows who made it, and changes appear straight away on other devices.
If I lose signal, do I lose my entries?
No. Entries you make offline wait in a queue on the device and are sent automatically once the connection returns. If two entries clash, the app asks which version you want to keep.
Where do the growth curves come from?
From the official WHO 2006 and CDC 2000 LMS tables, carried inside the app. Every measurement gets its z-score and nutritional status, and the calculation is tested against the SD columns WHO publishes itself.
Which immunisation schedule does it follow?
The schedule for children aged 0 to 18 recommended by the Indonesian Paediatric Society (IDAI) in 2023. Every dose has a recommended date, a Done or Due status, and a marker once it is overdue.
Why does the tracking day start at 19:00?
So that night feeds and night wakings land on the right day instead of being cut at midnight. The boundary follows the child's Nighttime Hours setting, and you can change it.
Who can see my pregnancy records?
Only you. Pregnancy and postpartum records are marked private and are never sent to another caregiver's session. The restriction is enforced on the server, and every access is logged.
Can I export or delete my data?
Yes. You can export your own data at any time. If you delete your account, it is deactivated at once, every session is revoked, and all data is permanently deleted after 30 days.
Which devices does it run on?
In a web browser, on Android and on iOS. The same entries and the same account, in sync across all of them.
