Sidelight: Baby Feed Timer
Which side next? One tap starts the timer on the left or the right, and Sidelight shows which side you used last. Bottle, pump, sleep and diapers take one tap too, for one baby or several, so a 3 a.m. feed stays a one-thumb job.
Not on the App Store yet. In English and Spanish when it arrives.

How it works
One tap. The right side, remembered.
Built for the feed where you have one free hand and no patience for menus.
-
Feeds
- Left and right breastfeeding timer: tap a side to start, tap the other to switch, pause and resume
- A next-side hint: the side opposite to the one you used last
- Time since the last feed, counted from when it started
- Bottle and pump, with the amount in ml or oz
- Edit the start or end, add a note, or undo, if you tapped late
-
Sleep, diapers and history
- A sleep timer: start when baby falls asleep, stop when they wake
- A diaper log: wet, dirty or both, saved with one tap
- History by day, with a 24-hour strip and filters for feeds, sleep and diapers
- Solids, medicine, activity, temperature and growth, in one log
- Add anything you forgot to log, edit it, or swipe to delete
- Several children, each with their own log
- A handover summary for whoever takes the next shift
-
On the Lock Screen and your wrist
- A Live Activity for a running feed or sleep, on the Lock Screen and in the Dynamic Island
- Switch side, pause or stop without unlocking the phone
- Widgets for the Home Screen and Lock Screen show the last feed and the next side
- An Apple Watch glance at the last feed and what comes next
- Siri and Shortcuts, for when your hands are full
- A gentle "Still feeding?" reminder if you forget to stop
The daily tool, and an optional Plus
More, only if you want it.
-
The daily log stays free
Every log, any number of children, the last 7 days, the week view, Lock Screen timers, widgets, the Watch glance, night mode, handover, backup and CSV. No time limit, no ads.
-
Sidelight Plus
Adds trends over time, a PDF report to bring to the pediatrician, logging from the Apple Watch and one-tap widgets.
-
No pressure while you feed
The purchase screen opens only when you tap a Plus feature or the Plus entry in Settings. Never in the middle of a feed.
The price will be on the App Store when Sidelight launches.
Private
Your log stays on your phone.
-
No account, no servers of ours
Feeds, sleep and diapers are saved only on your iPhone. There is nothing to sign up for, and we never receive your log.
-
No ads, no analytics, no tracking
No ad networks, no analytics tools, no tracking. One thing is recorded: if you buy Plus, Apple processes the payment and our purchase service, RevenueCat, records the purchase against an anonymous ID so we can count sales. Privacy policy
-
You decide what to share
Your log leaves the phone only when you export or share it yourself: a CSV, a PDF or a backup file protected by your passphrase. On the Apple Watch, Sidelight shows what your iPhone sends it.
Not medical advice
A timer, not a pediatrician.
Sidelight is a timer and log for your own records. It is not a medical device and gives no medical advice. The next-side hint only reminds you which side you used last. Talk to your pediatrician, midwife or lactation consultant about feeding and sleep, and call your doctor or emergency number if you are worried about your baby.
Questions
FAQ
What will be free, and what will cost money?
Every log, any number of children, the last 7 days, the week view, Lock Screen timers, widgets, the Watch glance, night mode, handover, backup and CSV stay free, with no ads. Sidelight Plus adds trends over time, the pediatrician PDF report, logging from the Apple Watch and one-tap widgets. The price will be on the App Store at launch.
How does the next-side hint work?
Sidelight looks at your most recent breastfeed and suggests the side opposite to the one you used last. It is a reminder based on your own log, not advice. Bottles and pump sessions don't change it.
Where is my data stored?
Only on your iPhone, with what the Watch shows coming from it. There is no account and no server of ours, so there is no sync between phones. You can make a backup file protected by your passphrase. If you back up your iPhone to iCloud or to a computer, the backup can include your log, like other app data. The privacy policy has the details, including what the purchase service records.
Does it work without internet?
Yes. Logging, the timers, the widgets and the Live Activity all work offline. You only need a connection to buy or restore Plus.
Which languages and devices?
English and Spanish, on iPhone with iOS 18 or later and Apple Watch with watchOS 11 or later.
