Pregnancy Due Date Calculator for Android

Pregnancy Due Date Calculator is a pregnancy tracking utility by Ingo Reschke that turns an estimated due date into a clear picture of the current pregnancy week, the days completed, and the days still remaining. It has been available since 2011 and has built a following of roughly 100,000 installs, which suggests a long-running tool rather than a short-lived experiment. The current build is version 4.4.5, published on 2026-10-12.

The core idea is simple: you provide your estimated due date, and the app does the arithmetic. From there it presents your exact week and day in the standard clinical notation, counts down to the due date, and pairs each of the 42 weeks with a fruit or vegetable comparison plus illustrated development notes. A home screen widget keeps progress visible without opening anything, weekly notifications mark each new week, and a Time Travel mode lets you check what stage any past or future date would represent. There is also recorded fetal heartbeat audio and shareable milestone cards for sending updates to family.

Privacy is the angle the app leans on hardest. Pregnancy data is described as staying strictly on the device, with no cloud synchronization, no tracking, and no third-party sharing of that information. That claim deserves a caveat: the permission list includes advertising-related identifiers and network access, so the app does serve ads, and the billing permission appears as well. What that means in practice is that your due date and progress are not the thing being transmitted, but the app is not a fully offline, permission-free tool either. Version 4.4.5 added in-app rating prompts, improved widget synchronization and stability, and refreshed the weekly development guides and fruit comparisons.

The app carries a 5.00 rating from 1,075 user ratings, is free to download, and is rated for Everyone. It requires Android 8.0 or newer. It is informational only and is not a substitute for care from a doctor or midwife.

What's new · 4.4.5

Version 4.4.5 arrived on October 12, 2026, bringing a few practical refinements to the pregnancy tracking experience. You can now rate the app without leaving it, thanks to a single-tap in-app review option, while widget synchronization has been made steadier and more reliable. The weekly fetal development guides and fruit-and-vegetable size comparisons have also been refreshed. As always, the app is designed for informational use and is not a substitute for care from a doctor or midwife.

Expecting parents who want a quick, private way to track their pregnancy week and countdown; people who prefer a widget and weekly reminders over opening an app daily; and anyone who enjoys the fruit-size comparisons and illustrated weekly development notes as a light way to follow along.

Enter your estimated due date as given by your doctor or midwife rather than calculating one yourself, since the week and day figures and the countdown all derive from that single value. If your dates change after a scan, update the entry so the widget and notifications stay accurate.

This is a focused, well-established pregnancy calculator with a strong privacy stance on the data it holds, a solid rating, and a free price tag. The trade-offs are the ad-supported model and its extra permissions, plus the fact that it is purely informational. Used alongside proper medical care, it works well as a lightweight daily companion.
