Cobook
One shared ledger for two
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Cobook — one ledger, two people.
Why Cobook
Couples, families and flatmates split the bill but never quite settle the account. Cobook gives you one shared ledger: who paid, who owes whom, clear at a glance — no more scrolling back through chat history to work it out.
Three seconds to log a spend
It opens straight onto the keypad. Amount and category live on the same screen — no jumping, no steps. Logging a spend should be over in three seconds.
Snap the receipt, let it do the typing
Photograph a receipt and the merchant, amount, date and category are filled in for you. Confirm and it's logged. The original image can be kept, so you can look at it again whenever you need to.
Works with no signal
Record anywhere; it syncs to your other devices once you're back online. You can use the whole app without an account — signing in is only for cloud backup and shared ledgers.
Where the money went
Category breakdown, daily trend and budget progress on one screen. The monthly report card can be shared as it is.
Also
· Multiple accounts and currencies, with manual exchange rates and saved transaction snapshots
· English and Chinese, four themes
· Built for iPhone and iPad — not a phone layout stretched wide
· Export a spreadsheet or a full backup at any time. The data is yours
· No ads, and nothing about you is ever sold
Subscription and terms
Cobook Pro comes as a monthly or yearly auto-renewable subscription, or as a one-off purchase. Prices are those shown by the App Store for your region. A subscription renews automatically unless it is turned off at least 24 hours before the current period ends, which you can do at any time in your App Store account settings; the one-week free trial is available once per subscription group. The date and amount of the first charge are stated directly above the purchase button.
