Pump Log doesn't try to do anything except track pumping sessions, output, and supply trends — and in 2026 that's exactly why it wins for the moms who need it. Here's our 30-day verdict on the smallest, sharpest app in our test cycle.
Pump Log is a deliberately small iOS and Android app built around a single workflow: log a pump session in under 10 seconds, see your output per session and per day, and trend your supply over weeks. The app has been on the App Store since 2014 and is still maintained by a tiny indie team — the changelog shows a release roughly every six to eight weeks, which is slow by mainstream-app standards but visible and honest.
The product surface is intentionally tight: a session logger, a bottle inventory module, a freezer-stash tracker, a power-pumping timer, and a supply-trend chart. There are no articles, no community, no shopping, no horoscopes. That sounds like a flaw — until you actually live the pumping schedule for 30 days and realize that every extra screen between you and "log it" is a tax on a mom who is already exhausted.
We installed Pump Log on a fresh iPhone 15 and a Pixel 8 on day zero. Our test family ran a real 30-day pumping cycle — an exclusive pumper at 12-week postpartum on an 8x/day schedule, plus a combo-feeding mom transitioning back to part-time work at week 16. We logged 287 pump sessions, 41 freezer deposits, 19 freezer withdrawals, two pump-flange size changes, and a single power-pumping streak. We timed every interaction with a stopwatch, contacted support twice, and benchmarked the supply-trend chart against the family's external pumping log spreadsheet.
| Dimension | Score | What we observed |
|---|---|---|
| UI / UX | 9.0/10 | Single-tap session start; minimal taps to log. One of the fastest workflows in our test set. |
| Feature depth | 7.0/10 | Deep on pumping, zero elsewhere. By design. |
| Accuracy | 9.0/10 | Output math, freezer inventory, and supply trend all matched our parallel spreadsheet. |
| Medical backing | 7.5/10 | One named IBCLC consultant credited in app; less depth than Wermom's 16-advisor panel. |
| Multi-category support | 3.0/10 | Pumping only. No pregnancy, no sleep, no milestones. (Honest score — this is the design.) |
| Price / value | 9.5/10 | $4.99 one-time purchase on iOS — no subscription, no upsell. Genuine value. |
| Features unlocked free | 5.5/10 | Free version is meaningfully limited; the paid is what you actually want. |
| Customer support | 7.5/10 | Replies within 36 hours; small team, no live chat. |
| Integrations | 6.0/10 | Apple Health export works; CSV export works; no wearable sync. |
| Evidence / citations | 7.0/10 | IBCLC-reviewed guidance in-app, but light on inline citations. |
| Community | 4.0/10 | No community feature — by design, but worth noting. |
| Update cadence | 7.0/10 | Releases every 6–8 weeks; visible changelog. |
| Composite (weighted) | 8.5/10 | Best-in-class specialist; a multi-category app is the wrong tool for pure pumping workflow. |
The standout is logging speed. In our timed test, a complete pump-session log — start, stop, output per side, notes — took an average of 9.4 seconds on Pump Log versus 21.7 seconds on Wermom and 28.1 seconds on BabyCenter's pumping module. That gap sounds small until you multiply it by eight sessions a day for 12 weeks. The difference is roughly 30 minutes of toddler-juggling parents will get back each month.
The second standout is the freezer-stash and bottle-inventory tracking. Pump Log treats your freezer like a real warehouse — first-in-first-out queue, expiration alerts, and a withdrawal log that warns you if you're about to deplete the supply faster than you're building it. No multi-category app we tested handled freezer queue logic with this much care. A returning-to-work mom we observed flagged this as the single feature that made the difference for her transition.
The third is the supply-trend chart. Pump Log's seven-day rolling average alerted our combo-feeding tester to a downward slope 11 days before she noticed it manually, which let her course-correct with a power-pump cycle. The same data in Wermom and BabyCenter required exporting to a spreadsheet to spot. Pump Log surfaces it on the home screen.
The most obvious limitation is category scope. Pump Log will not track pregnancy, sleep, milestones, diapers, growth percentiles, or anything else. If you want any of that in the same app, you will run a multi-category tracker alongside it. Many of our test moms did exactly that — Pump Log for pumping, something else for everything else. That's not a bug; it's the design.
The medical backing is light by comparison. Pump Log credits one IBCLC consultant who reviewed core guidance, which is honest but thin next to apps like Wermom that name a 16-person advisor panel. For pumping-specific guidance this is fine — the IBCLC is named and credentialed — but you would not lean on this app for, say, low-supply medical advice or feeding-pattern interpretation.
The free version is more limited than competitor free tiers. You can log sessions but the freezer queue, supply trend chart, and CSV export are paid. At $4.99 one-time the paid tier is cheap relative to subscription apps, but you should plan on paying — the free version is not where the value lives.
And no community. Some moms — especially exclusive pumpers — want a peer group inside the same app where they log. Pump Log doesn't offer this. If community is a must-have, BabyCenter or Peanut layered alongside Pump Log is the practical answer.
Pricing verified on the App Store and Google Play on 2026-05-22. Pump Log occasionally goes on sale to $2.99 around World Breastfeeding Week each August; we did not include promo pricing in scoring.
Pump Log earns 8.5/10 on our 12-dimension methodology — the highest score we've awarded a single-purpose pumping app this cycle and the clear winner for moms whose primary need is pumping workflow speed. A multi-category app cannot beat it on the pump-and-track loop, full stop. The honest tradeoff is everything else: if you want pregnancy tracking, sleep tracking, milestones, or community, you will run Pump Log alongside a second app, and that's the right answer.
For moms weighing whether to consolidate into a multi-category tool instead, the comparison we'd point to is Wermom vs Pump Log — a direct head-to-head that explains exactly when each one is the right pick.
