Oct 2026: Gem 5.0 has an all-new sharing that's more reliable. Please update the app and reinvite your partner
With Gem, you can manage budgets and expenses together with a partner. Here's how it works:
Available on Gem 5.0 (released Oct 25, 2026)
If changes aren't showing up between you and your partner, Gem can check your sync and show you what's wrong.
Gem runs 4 checks, in order. If a check fails, the checks after it are skipped. Green means all good, yellow means something is still in progress, and red means something needs your attention.
iCloud
Gem syncs through your iCloud account, so your iPhone needs to be online and signed in to iCloud.
Sharing
Checks that your shared data is set up and that your partner joined.
Incoming changes
Checks that Gem can receive your partner's latest changes. Yellow means new changes just arrived, which is normal. If you see red, please contact us so we can help.
Outgoing changes
Checks that all your changes were sent to your partner. Yellow means some changes are still waiting to be sent: go back and open Sync status again in a few moments. If it stays yellow or turns red, please contact us so we can help.
To contact us, tap the share button on the top-right corner of the Sync status screen and send the sync log to human@shelftwo.com. It helps us find the problem faster

Gem doesn't sync attachments, so it's best to avoid adding them to expenses when sharing with a partner.
