YuvaTwo of you.
One log.
Feeds, sleep and diapers in one tap, on both parents’ phones the moment they happen. Made for 3 a.m., free for both of you.

- 01
Start a log
Your baby’s name and birthday. No account, no e-mail, no password.
- 02
Invite your partner
They scan a code on your screen, or open the link you send. Each of you on your own phone, both free.

Log in a tap
Breastfeed with a left/right timer, a bottle with last time’s amount, a diaper in one touch. It shows up on the other phone right away.
It won’t light up the room.
From 9 p.m. to 7 a.m. Yuva turns dim amber on black, with big buttons you can hit one-handed while holding a baby. The rest of the day it’s a calm paper log.
We read what parents hate about baby trackers. Then fixed it.
Sharing is free
Other trackers charge to sync with your partner. In Yuva both parents log for free, each on their own phone, without sharing a password.
Nothing gets lost
Every entry syncs on its own, so when you both log at once, both entries stay. If you both edit the same one, the later edit wins on both phones.
Works offline
Everything is saved on your phone first and syncs when there’s a connection: in the hospital, on the plane, in the basement.
Handoffs
Going to sleep or to work? Hand over: Yuva writes when she last ate, which side, how long she’s been awake and what medicine she had. They see it until they tap “Got it”.
Wet and dirty in one tap
A mixed diaper is one entry. And the time is always written next to “2 h ago”, because at night you want both.
Honest health notes
A temperature that needs a doctor, a stool colour worth a call: Yuva says so, plainly, and never gives doses or diagnoses.
Good to know.
Is sharing with my partner really free?
Yes. Two phones share one log for free, forever. Yuva Pro adds up to 12 people (grandparents, a nanny) and insight features, and one Pro covers the whole family.
What if we both log at the same moment?
Both entries are kept. Each entry syncs on its own, so nothing overwrites anything else. If you both edit the same entry, the later change wins and appears on both phones.
Does it work without internet?
Yes. Every entry is saved on the phone first. It syncs when you’re back online, and the other phone catches up.
Twins?
Add as many babies as you like and switch between them at the top of Today. Free.
What does Pro add?
The next likely sleep window from your baby’s age and last wake-up, trends over 7, 14 and 30 days, WHO growth percentiles and charts, a PDF report for the doctor, and more than two people in the family. Everything you need to log stays free.
Is Yuva medical advice?
No. It is a log. It points out a few clear warning signs (a fever in a young baby, a pale, red or black stool) and tells you to call your doctor. If you’re worried, call your doctor.
Where is our data kept?
On your phones and, so the phones can sync, on our server. No ads, no tracking, never sold. The privacy page has the details.
How do we delete everything?
Settings › Delete all data. If you’re the last phone in the family, the log is deleted from our server too.
