How to sync a habit tracker between Mac and Windows, and iPhone and Android

To sync a habit tracker between a Mac and a Windows PC, or between an iPhone and an Android phone, you need an app that is built for both sides and has its own sync service. Apple's iCloud doesn't reach Android or Windows, and Google's phone backup doesn't reach an iPhone or a Mac. So the app itself has to carry your data across.

Before you commit to a tracker, check three things: does it have a native app on every device you use, does it sync between them, and is that sync included or paid. This guide walks through each.

Why most habit trackers stay on one side

Many habit trackers are built for one platform. Some are Apple only and sync through iCloud. Others are Android only and back up through Google. Both approaches work well inside their own world. The trouble starts when your phone is an Android, your laptop is a Mac, and your work machine runs Windows.

Built-in backups are also usually for restoring the same kind of device. An iPhone backup restores to an iPhone. An Android backup restores to an Android phone. Neither one opens on the other.

What to check before you choose

• A native app on each device. Look on the App Store, Google Play and the Microsoft Store, or the maker's download page. A web page in a browser tab won't give you a widget.
• Sync, and which way it goes. Some apps sync Apple devices only. Ask whether a check-in on your phone shows up on your PC.
• Included or paid. Cross-platform sync needs a server, so many apps charge for it. That's reasonable. Just know before you start.
• Privacy. Find out if your data is encrypted before it leaves your device, and whether the company can read it.
• Your subscription. If you pay on one store, check whether it unlocks the app on the others or whether you'd pay twice.

Mac and Windows

This is the hardest pair. Windows has no iCloud app sync for third party apps, and a Mac has no Google phone backup. A tracker that syncs these two has to run its own service.

Also check what Classic does on Windows. If a Classic Windows app keeps no backup at all, your history lives on that one PC, and a sync service is also your backup.

iPhone and Android

This comes up most in mixed households and when people switch phones. If you're moving from one to the other, check whether the app can bring your history across. If you're in a household with both, check whether two people on different phones can each use the same app, even if they keep separate data.

How to test sync before you rely on it

• Install the app on two devices.
• Turn on sync on the first and create something small.
• Turn on sync on the second and wait for it to appear.
• Check in on the second device, then look on the first.
• Save any recovery code or password the app gives you somewhere safe.

If anything only goes one way, you've found out before it matters.

How Reveal the Dream syncs

Reveal the Dream is a goal tracker with native apps for iPhone, iPad, Mac, Android, Windows and Linux. You pick a photo of a goal, it starts covered, and each daily check-in uncovers one piece. Miss a day and that piece stays covered. Nothing resets.

Here's what is included and what is Premium, so there are no surprises.

• Classic. Each device backs up its own journeys. On iPhone, iPad and Mac that is through iCloud. On Android it is through your own Google account. The Classic Windows app keeps no backup of its own, so your journeys live on that PC.
• Premium. Your journeys and photos sync between Apple, Android, Windows and Linux. Check in on an Android phone and your Mac or PC has it when it syncs. For a Windows PC, that sync is also its backup.

Premium sync keeps one copy of your journeys that is encrypted on your device before it is uploaded. We don't hold a key, so we can't read your goals or see your photos. When you turn it on, you get a recovery code. Keep it safe, because another device needs it to open your copy, and we can't recover it for you.

You purchase Premium once, on the App Store, Google Play, the Microsoft Store or our site. On another platform you sign in with Apple, Google or Microsoft, a QR code from your phone, or a six digit code we email you. That sign-in carries the subscription and nothing else. The full walkthrough is on the cross-platform habit tracker page.

Which setup do you have?

• iPhone and Mac. Look for an app with good iCloud support, or a tracker with its own sync.
• Android phone and Windows PC. You need an app with its own sync service and a Windows app.
• Mac at home, Windows at work. Same as above. Check the Windows app has a widget or a small window you can keep in view. Our guide to adding a habit tracker widget to Windows 11 covers that.
• Switching from iPhone to Android, or back. Check the app can move your history before you wipe the old phone.

The test is simple. Check in on the device in your pocket, then look at the one on your desk.
