Wonder Weeks alternatives: leaps inside a baby tracker

Pixy is ours, so read the rest knowing that. Every claim about The Wonder Weeks below comes from its own App Store listing, linked at the foot, read on 6 October 2026.

Our pick, if you want one app

What The Wonder Weeks does

It is the leap app, and it does that thoroughly. Its listing describes ten mental leaps in the first twenty months, a personalised leap schedule with start and end dates, notifications when a leap is about to start, the signals and new skills of each leap, 77 playtime games, a diary, a link to your partner’s app, a forum and videos. It is free to download, with subscriptions and e-book chapters as in-app purchases.

What Pixy shows about leaps, and what it does not

Pixy is a tracker first. For babies up to twenty months, a card on its home screen names the developmental phase your baby is in, or the next one coming, with a line on what it tends to bring: focusing and listening, discovering hands, cause and effect, distance and depth, and so on, ten in all. Tap it for a short explanation.

That is the whole of it. Pixy does not send leap notifications, has no leap games or e-book, and does not chart leaps day by day. What it adds is everything around the leap: the hard week shows up in the sleep log, the nap prediction adjusts to what your baby actually did, and the feeds and routines are in the same place.

Side by side

• Keep The Wonder Weeks if leaps are the reason you have an app at all. Its schedule, notifications and games go far deeper than a card on a home screen.
• Pixy if you want one app for the day, with the leap shown in passing rather than as the centre of it.

A word on leap calendars

Leap calendars give average ages, and babies vary widely. A baby who does not have a hard week at the predicted time is not behind, and deciding a difficult week must be a leap because the calendar says so can mean a real cause gets missed. Our guide to growth spurts and leaps sets out how to tell them apart.
