Bump Pulse: Contraction Timer

Review by eFreeware

If you are expecting a baby and want a straightforward way to time contractions, Bump Pulse is built for exactly that moment. It is a contraction timer, counter and tracker for the day itself, and it is designed to be used from the first twinge rather than after a setup process. The developer describes it as a calm labor companion, and the feature set backs that up: one tap to start, one to stop, and the numbers you need without menus in the way.

Nothing costs anything up front: there are no ads and no subscription, and you pay once for the extras. It has been installed more than 10,000 times and holds a 4.7 average from 122 ratings. It was released in May 2025, so it is a relatively new app, but the recent updates suggest active work on it.

What appeals to me most is the focus. There are plenty of apps that try to be a pregnancy hub, but this one narrows in on the hours when you actually need a timer. That makes it easy to judge: if you want a contraction tracker you can open and use immediately, the shape of this app makes sense.

One tap, and the pattern starts to show

The core experience is as simple as it gets. You tap once when a contraction starts and once when it ends, and the app records the duration and the interval between contractions. It also shows the averages for the last hour, which gives you a sense of whether things are speeding up or settling down. There is no setup and no menu navigation required to begin.

Bump Pulse also charts each session across the hours, not just the raw numbers. Plotting both length and spacing makes a shift easier to spot. That helps when you are trying to tell true labor from Braxton Hicks, which is hard to judge from memory mid-contraction.

Any entry can carry a note or an intensity, and a start time can be corrected later if a contraction caught you busy. The app also tracks the 5-1-1 or 4-1-1 rule, or a rule of your own, and shows how close you are to it. That gives the timing a purpose beyond record-keeping: it helps you decide when to call your midwife or doctor, though the developer is clear that it is not a medical device and cannot stand in for their advice.

Milestones sit on the same timeline as the contractions. You can also log your water breaking, your arrival at the hospital, and the birth itself. Afterwards, you can pass a clear summary to your midwife or doctor. It is a neat way to keep the story of the labor in one place rather than scattered across notes and memory.

Partner sharing that works from another room or another city

The live sharing feature is the one I would expect to matter most to couples. A link lets your partner watch the same session on their own handset, nearby or far away. During a contraction your hands may be occupied, so a birth partner can run the timer instead, which is a practical touch.

The same link works for a doula, a midwife, or whoever else you want, for as long as you want. Sharing is limited to the people you invite, and you can turn the link off whenever you like. That combination of access and control feels considered, especially for something as personal as labor.

I would expect this to appeal to partners who want to be useful rather than just present. Instead of watching the clock themselves, they can run the timer and watch the pattern alongside you. It turns a solo task into something shared without requiring both people to be in the same place.

On your wrist and on your home screen

There is a Wear OS version, so the timer can be run from your watch. On the watch you see the count, the average length, the interval over the past hour, and recent entries. Once started, the timer remains visible on your watch face until you end it, so a glance is enough to check progress without picking up your phone.

Widgets come in three sizes. They show the timer, recent entries and the last hour, and you can start or stop from the home screen. For anyone who has fumbled with a phone mid-contraction, that shortcut is likely to be welcome.

These additions came in a recent update, along with seventeen more languages and right-to-left layout for Arabic and Hebrew. The app has also had bug fixes and improvements. It is a young app, but the direction of travel is clear: making the timer easier to reach in the moments when reaching for it is hardest.

Guides for the weeks before and the day itself

There is also a bag checklist for the hospital and short guides on early labor, false labor, the 5-1-1 rule, and when to call. These are the kinds of things first-time parents often end up searching for at odd hours, so having them in the same app as the timer is convenient.

Before labor, it offers a weekly probability, a birth weight estimate, and reading on the first weeks after birth. These are not the core of the app, but they round it out for anyone who wants one place to check in during the third trimester.

I would treat the guides as a supplement rather than the main event. The timer and the pattern view are what make Bump Pulse worth installing; the rest is useful context that saves you from switching between apps when you are already tired.

What it needs, and the limits built into it

Bump Pulse needs neither a signal nor an account, and nothing leaves your phone unless you decide to share it. That is a meaningful design choice for labor, when you may be in a hospital with poor reception or simply not want to create another login. You can turn the share link off whenever you want, so sharing is opt-in rather than automatic.

You pay once for the extras, so there is no recurring cost. It is rated for Everyone and sits in the Parenting category.

The limits are mostly about scope. It is built around the labor day itself rather than pregnancy tracking more broadly, so it is not trying to be a general pregnancy app. The Wear OS features and widgets add to the phone timer.

In practice, the trade-offs are modest. You get a focused tool that does its job without asking for much, and the developer is explicit about what it is not. For a free app with no ads, that is a fair bargain.

Who it suits

It fits first-time parents, partners who want to help, and people who prefer watching the person to watching the clock. That last phrase captures the spirit well. If you are the kind of person who wants to be present rather than buried in a screen, the one-tap timing and the live sharing are designed to keep you in the room.

It also suits couples who are planning a hospital birth and want a clear record to hand over. The summary you can share with a midwife or doctor, along with the milestones on the timeline, gives the care team a quick picture of how labor has progressed. For a doula or midwife supporting a birth, the live link offers a way to follow along without being handed a phone.

If you prefer a simple stopwatch and a notebook, this app does more than you need. But for anyone who wants the pattern visible and the timing handled, the focus here is a strength rather than a limitation.

A focused timer for the labor day

Bump Pulse is a well-scoped contraction timer with a few features that genuinely matter: one-tap timing, a visual timeline, live partner sharing, and a watch app that keeps the timer within reach. The 4.7 average from 122 ratings suggests that the people using it are finding it useful.

I would recommend it to first-time parents, birth partners and anyone supporting a labor who wants to follow the pattern rather than the clock.

If you are packing a hospital bag and want one less thing to think about, this is a sensible app to have on your phone before the day arrives.

What's new in version 3.6.0

Home screen widgets in three sizes: start and stop a contraction and see the last hour without opening the app. Bump Pulse is now on Wear OS: start and stop from your wrist, and see the last hour's count, average length and interval. Seventeen more languages, with right-to-left layout for Arabic and Hebrew. Bug fixes and improvements.
