Erby helps you easily track and record breastfeeding, newborn activity, sleep statistics. It's also a handy food diary for your baby and nursing mom!
You will be able to make sure that the newborn is getting enough breast milk and to establish the daily baby care. Enter information about food, beverages, medications and supplements you are taking. This will help identify allergic reactions in the infant.
LACTATION
Start the breastfeeding timer with one click! Track the duration of feedings, easily remember which breast you fed the last time: this will help to establish breastfeeding and avoid lactostasis. Record data on pumping and responses to the first complementary foods.

The package embeds several distinct advertising or mediation SDKs — a stack built for ad volume, not for a single house ad.

sha256:10d2aaecbab218d4051ff5a547411c3f26c0777f7f9ed9534c2eaee6f0f8c6dcPaywall is server-configured and A/B tested via Adapty — the offer shown can differ per user
The app ships a remote paywall-experimentation SDK, so the offer shown is configured server-side and may differ per user — including from anything we or a reviewer saw.

sha256:10d2aaecbab218d4051ff5a547411c3f26c0777f7f9ed9534c2eaee6f0f8c6dcSpecific evidence of a useful property, within the stated scope.
The developer's store data-safety disclosure states that data deletion can be requested; we have not seen a deletion control in the app's own text
The developer's data-safety disclosure on the store states that users can request deletion of their data, or the app's own text offers a way to delete the account. This restates what the developer declares; it is not a test of whether deletion works. Apple publishes no equivalent disclosure, so on an Apple-only listing only the app's own text can support it.
Open observations that have not cleared the evidence bar.
Ships a purchase screen ("Paywall") with no dismiss, skip or "continue free" text anywhere in the package
This observation has not cleared the required evidence standard.
A paywall screen ships with no dismiss, skip or 'maybe later' affordance anywhere in the package, so the app's own text offers no way in without paying.

This observation has not cleared the required evidence standard.
Cancelling the subscription is blocked, hidden, multi-step, or simply does not take effect.

“Not assessed” means we could not measure it. It is never a zero and never a pass.

erby-feeding-and-sleep-trackerAssessed 2026-10-30 from 407 user reviews, the app's package, the store listing and its privacy label.
What the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
This assessment is produced automatically. Six independent signals are read — user reviews, SDKs in the app package, the app's own on-screen text, the app manifest, the store listing and the store privacy disclosure — and each candidate finding is filed under the sources that support it.
No charge stands on one kind of evidence — with one published exception. A finding is either a measured fact that anyone can reproduce (an ad SDK is in the package; every recurring plan the store lists is named as weekly, the term read from the purchase names, with a list cut off at the store’s 10-item maximum not assessed; the privacy label omits a tracker we can see), or it is an interpretation — and an interpretation needs independent sources to agree before it reaches the catch list. The exception is a harm only users can see: a charge may publish from reviews alone, as “Reported by N users”, once enough reviewers raise it to clear that charge’s own published bar. That agreement rule is what replaced the human reviewer, not a model’s confidence.
There is no overall score, on purpose. A 0–99 number was published here until 2026-09-15. It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an observation. What publishes instead is a row of measurements, each of which says what was counted and, where we could not look, says that instead.
Findings under One source only are real reports we do not stand behind as findings. They are shown because withholding them entirely would hide a genuine complaint, and labelled because publishing them as charges would be an accusation off a single source.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
