Baby Tracker App for Twins and Siblings

Estrelu is a baby tracker app for twins, siblings and families with up to 4 little ones. Each child has their own log, and "all" mode records a shared feed, diaper, bath, walk or nap for everyone in one tap. One plan covers the whole family. It runs in your browser, works offline, and has no ads.

Two babies, one pair of hands

You just fed both twins, changed both diapers, and now you need to log all of it twice, with one hand, while one of them starts crying again. Most trackers make you switch profiles and repeat every entry. In Estrelu, you switch to "all," tap once, and both logs are up to date.

How Estrelu works for twins and siblings

1. Add each child. Create a profile for each baby or toddler, up to 4. Each one keeps separate records.
2. Log for one child. Pick a child and tap as usual: sleep, feeding or diaper.
3. Log for everyone. Switch to "all" mode to copy shared entries to every child: feeds, diapers, baths, walks and sleep.
4. Fix one entry if needed. If one twin woke early, edit just that child's entry after the fact.
5. Bring in help. When family accounts launch, invite a partner, grandparent or nanny with a one-time code. No extra charge per adult.

A typical baby tracker vs Estrelu

What it's based on and what it doesn't do

Estrelu doesn't assume your twins run on the same schedule. Shared entries are a shortcut, not a merge. Each child's record stays separate, so each sleep forecast learns from that child's own day.

What Estrelu does not do:

• It does not set a feeding or sleep schedule for your twins.
• It does not offer consultations with sleep or feeding specialists.
• It does not connect to baby monitors or smart devices.

Feeding two at once? The baby feeding tracker covers breast with a side timer and bottles in oz or ml. When someone else takes over, the caregiver handoff sends a plain-text summary through any messenger. If you're coming from another app, you can import your data from a CSV file. Columns are recognized by name, and importing again doesn't create duplicates.

Logging at night with two babies

At night, Estrelu switches to a dark screen with swipe gestures: up for sleep, left for a bottle, right for the breast, down for a diaper. A short vibration confirms each entry, so you don't have to look closely at the screen. You can undo any entry with one tap and correct it in the morning. Sounds and the night screen work offline, so a weak signal in the nursery doesn't matter.

Pricing for the whole family

Try Estrelu free for 5 days, with no card required. After that, it's $4.99 a month, $44.99 a year (about $3.75 a month) or $79 once for lifetime access. Every plan includes every feature, for every adult and up to 4 children.

Estrelu is not a medical device. It does not diagnose, calculate doses or replace your pediatrician.
