Which devices Plum works on, and how signing in works

By the Plum team · Checked against the app on September 26, 2026

Plum is an iPhone app, and that’s the short answer to most questions about devices. The rest of this page covers how signing in works and why there’s an account at all.

Devices

There’s no Android version, no iPad layout, no Apple Watch app and no home screen widget yet. The phone you log on is the phone that gets reminders, but your data isn’t tied to it, because it lives in your account.

Signing in

You sign in with Apple or Google. Apple lets you hide your email address behind a relay, and that works fine with Plum. Because of the account, a new phone picks up where the old one left off and a group of friends can see each other’s dates. You can also delete everything in one go, which is on deleting your account.

If you sign in with a different method later and it carries the same verified email, Plum links it to your existing account rather than making a new one.

Where your data lives

Your data lives on Plum’s servers, encrypted in transit and at rest, with a copy on your phone for speed. That’s different from apps that keep everything on the phone, and it’s a deliberate trade for sync and groups. The full picture, including which services Plum talks to, is on how Plum handles your data.

Common questions

Is Plum on Android?

No. Plum is an iPhone app, and there isn’t an Android version yet. That also means a friend on Android can’t join your group for now.

Does Plum work on iPad or Apple Watch?

Plum is built for iPhone. An iPad can run it in the iPhone-sized window Apple provides, but there’s no iPad layout. There’s no Apple Watch app or widget either.

Does Plum sync with Apple Health?

No. Plum doesn’t read from Apple Health or write to it, and it doesn’t connect to Oura, Whoop, Garmin or any other tracker. Cycle days you log in Plum stay in Plum, and you’d have to enter days from Apple Health again by hand.

Does Plum work offline?

Not really. What you log is saved on Plum’s servers, so the app needs a connection to store it and to show a group’s timeline. You can open the app and read what’s already loaded, but plan on being online when you log.

Can I export my data out of Plum?

Not yet. There’s no export or download file today, so the way out is deleting the account, which erases everything rather than handing it back. Email us if you need a copy and we’ll see what we can do.

Which iOS version does Plum need?

The App Store listing shows the current minimum, and the store won’t offer the app to a phone that’s below it.

Do I have to make an account?

Yes. You sign in with Apple or Google, and there’s no email-and-password option. The account is what lets your history sync to a new phone and lets a group see your dates. Plum isn’t an on-device-only tracker and doesn’t claim to be.

I signed in with Apple once and Google another time. Do I have two accounts?

Not if both use the same email address. Plum links a second sign-in method to the account that already holds that verified email, so you land in the same history either way. If you used a different address, you have two accounts, and support can help merge or remove one.

How do I move Plum to a new iPhone?

Install Plum and sign in the same way you did before. Your history is on Plum’s servers, so it appears on the new phone. If Premium doesn’t show as active, tap Restore purchases in Me.

Will Plum sign me out?

Only if you don’t open the app for a year. Otherwise you stay signed in for as long as you keep using it.
