Since Apple first introduced the Health app in 2014, its health and fitness ambitions have expanded dramatically. But with that growth has come added complexity. What started as a simple hub for health data has turned into something that can feel overwhelming when all you want is a quick look at your daily activity.

That’s where an app like ActivityTracker comes in. It provides a streamlined, focused experience for keeping tabs on movement without the clutter.

Overview

ActivityTracker is an app for iOS and Android that makes it easy to monitor your daily activity at a glance. It uses the motion coprocessor built into iPhones to track steps, distance, calories, active time, and even flights of stairs without draining your battery.

What sets ActivityTracker apart from Apple’s own Health app is its simplicity. The interface is clean and straightforward, showing your activity across hourly, daily, weekly, and monthly views so you can spot trends without getting lost in endless charts. It’s less about hardcore fitness training and more about encouraging steady, everyday movement.

Design & Interface

Speaking of encouragement, I’ll mention that one of my favorite features of the app is its default approach to notifications. I received a single at the end of each day reminding me to review the current day’s activity, and at the end of the week, I get a notification to review last week’s activity. That’s it. I can’t tell you how many health and fitness apps I’ve used over the years that, by default, bombard you with notifications. ActivityTracker strikes a nice balance here.

ActivityTracker sports a simple, clean, and focused design. The widgets do a good job of blending in without being bland. I’m personally not a fan of “loud” widgets.

The Today tab gives you an at-a-glance view of your current day’s activity metrics. You can quickly view stats for other days in the week by selecting a day from the week view along the bottom of the dashboard.

The Trends tab is where you’ll find historical charts of your activity data. Tapping into some of the charts, like the days, weeks, or years charts, lets you toggle through each of the supported activity types by tapping on the chart.

Activity Tracking

On the iOS side, ActivityTracker integrates with Apple Health and supports importing historical activity data into the app. This was a nice surprise and kind of rare in my experience. Most of the fitness apps I’ve used over the years will integrate with Health, but not pull in any data from before the day you connected the app, which always seemed strange to me. The whole point of having Apple Health as a centralized repository of health data was that apps would be able to leverage all of that data without having to implement custom integrations with other apps.

From the Activities tab, you can track supported exercises with GPS via your phone or watch. Supported exercise types are:

• Walking
• Running
• Biking
• Hiking

You can review your metrics and route after the fact in the Activities tab. The charts here remind me a bit of how charts looked in the original version of the Health app (which is not at all a bad thing).

Overall, the app has a thoughtful layout that keeps things easy to navigate.

Apple Watch

There’s also an Apple Watch version of the app that runs natively on watchOS. It leverages the sensors on the watch itself, so it can work completely standalone for tracking activity and workouts. It, of course, offers complications for metrics like Step Count, something Apple notably doesn’t provide. The downside to the standalone nature of the watchOS app is that it may have different numbers than the iOS app. Syncing the watch and iOS is a feature, but only if you buy the Pro version of the app. I would naively think that if an app integrates with Apple Health, using it as a centralized repository would mean that data would just naturally be in sync.

Pro Version

The free version of ActivityTracker is pretty full featured, but there is a Pro version of ActivityTracker that can be unlocked via in-app purchase. Some of the features it offers are:

• Customizable metrics, letting you prioritize steps, calories, or distance.
• Celebratory animations when you hit your activity goals.
• Apple Health sync, so all your activity stays in one place.
• Complications and themes, for customizing how and where you view your data.
• Data backup and export, so you don’t lose progress if you switch devices.

Summary

Pros	Cons
Clean, focused user interface	Device syncing locked behind Pro version
Beautifully designed widgets
Apple Health sync pulls in all historical data, unlike many health apps

ActivityTracker strikes a smart balance: it’s powerful enough to give you meaningful insights into your daily activity, but simple enough that it never feels overwhelming. While I wish some of the features in the Pro version were included in the free version to make it feel a bit more robust, I think the overall value proposition of the app makes sense. The free version is certainly worth a try if you’re looking for a focused app for tracking your daily activity.
