## What is Zen Otto?

Track breastfeeding, bottles, diapers and baby sleep with one hand. Zen Otto keeps your newborn's feeding and care log together, whether you are holding your baby, handing over to another caregiver, or checking the night at 3am.

KEEP THE DAY TOGETHER
Time breastfeeding on either side. Record bottles in milliliters or ounces, formula or expressed milk. Log wet and dirty diapers, pumping sessions, sleep, weight, solids, allergen exposures and vaccination details.

MADE FOR ONE HAND
Start and stop a feed with the dial. Keep everyday controls within reach, and choose the original interface or the Pink and Blue themes. Review the daily log, weekly summary and nighttime record without piecing the day together from memory.

SHARE THE CARE
Keep a separate log for each baby. Invite caregivers through iCloud sharing when you want to keep a shared record. Review the handover screen, edit a missed entry at the time it happened, and export a record when you need it.

REMINDERS AND NIGHTTIME TOOLS
Choose the reminders you want. Supported live activities keep a running feed or sleep visible on the Lock Screen. The built-in sound machine can continue playing when you lock your phone.

YOUR PHONE, ICLOUD AND YOUR CHOICES
Care records are stored on your iPhone. iCloud sync is enabled by default when available; you can turn it off in Settings, with changes taking effect on the next app launch. Sharing with caregivers is separate from syncing your own devices and uses Apple's CloudKit service. Turning off device sync does not stop an existing caregiver share; manage that through the sharing controls.

No Zen Otto account is required, and the app has no advertising. Usage analytics, handled by PostHog, are on by default and can be turned off in Settings. They report app interactions and limited context, not the contents of your care records. Read the privacy policy for analytics, iCloud, sharing and deletion details.

A PLAN IS REQUIRED
After setup, choose a monthly or yearly subscription, or a one-time purchase. Eligible subscriptions include a three-day free trial; Apple confirms eligibility and local pricing before purchase. The one-time purchase does not include a subscription trial. Ending a subscription does not delete your logged records. The one-time purchase does not renew.

Zen Otto records care information. It is not a medical device and does not provide medical advice, diagnose your baby or replace your doctor.

## Version history (last 5 releases)

### 1.3.4 — 2026-10-09

Subscriptions are easier to manage. We’ve improved plan loading, trial details, purchase recovery and restore guidance, with clearer next steps when Apple is still processing a purchase.

### 1.3.3 — 2026-09-28

You can write to me from inside Zen Otto now. Open More, then Write to the Founder.

I read every message myself and write back within a few hours, 24 at most. A bug, a wish, a thank-you. Anything.

Tell me what would make this better for you and your baby.

### 1.3.2 — 2026-09-19

Yesterday is not gone any more.

A row of dates now sits above your log. Tap one and the whole day comes back, feed by feed. The little bar under each date shows how full that day was. It is a shape, never a score.

Potty is here too. Wee, poo or both, one tap each. Tracking, not training, and it starts long before the potty does.

What is typical now runs to two years. A one year old was being shown a six month old's guidance. That was our mistake, and it is fixed.

The Record screen had a tidy up. Two tiles to a row, the name beside its icon, and today's count where you can actually see it.

Thank you for being up at 3am with us.

### 1.3.1 — 2026-09-18

A warmer Zen Otto, and two widgets that finally work.

EVERY SCREEN, REWRITTEN
The app used to read like a settings file. Now it sounds like someone who has done this before and is not going to tell you what to do. Reminders are Gentle nudges, and they still only ever say how long it has been. Never that a feed is due.

THE WIDGETS
The Lock Screen and home screen now match the app instead of the old theme. The two home screen widgets also show your real log, which, honestly, they never did before. That is fixed.

UNITS, AND A FACE
Choose metric or imperial, weight included, in Settings or during setup. You can add a photo of your baby while setting up too.

USAGE ANALYTICS
New in this version, and on by default. They tell us which screens get opened so we know what to improve. They never carry anything you have logged: no names, no photos, no volumes, weights or temperatures. Switch them off any time in Settings, under iCloud and privacy.

### 1.3 — 2026-09-08

A whole new look: Pink and Blue, a soft, illustrated alternate to Zen Otto's original design, on every screen in the app. It's set automatically once you tell Zen Otto your baby's name at set up, and you can switch it - or go back to the original - anytime in Settings.

Pick your own app icon too, right there next to the theme.

Smaller fixes: a few screens read their labels correctly for VoiceOver now, and the power-on screen animates the way it's meant to.
