Cash Book Support: Email a Human, Not a Chatbot

There is no support desk. There is an inbox, and one of us reads it.

That makes us slower than a chatbot and considerably more useful, because the person replying can go and look at the code. No phone line. No ticket number. Nobody telling you your request is important to us.

Contact

Write to hello@02apps.com. Say what happened, and send a screenshot if you can, because one screenshot usually saves about three emails. Replies land within a day most of the time. The same address is in the app under Settings → Support.

Common fixes

A purchase did not come back

Open Settings in Cash Book and tap Restore Purchases. The thing that catches most people: the iPhone has to be signed into the same Apple ID that bought the plan. A purchase made under a different Apple ID will not appear, and we cannot move it across for you, because Apple holds the receipt and we never see it.

Voice says it heard nothing

Very short or very quiet clips get rejected rather than guessed at, and that is deliberate. A tracker that invents a number is worse than one that shrugs. Hold the phone a little closer and say a full phrase, like "twelve euros lunch at Beshamel". Voice also needs a connection, since the audio is parsed by an AI model and not on the phone.

The camera could not read a receipt

Light does more here than anything else you can change. Lay the receipt flat, keep shadows off the numbers, get the total inside the frame. Faded thermal paper sometimes cannot be read at all, and retrying will not rescue it; tap the plus button and type the amount. The snap needs a connection too.

Apple Pay auto-logging is not firing

Four things all have to be true, and it is nearly always the third one. Your iPhone runs iOS 17 or later. At least one card is in Wallet. The automation uses the "Transaction" trigger, which sits at the very bottom of the trigger list under Wallet, not under Apps. And the Cash Book action "Log purchase" is inside the automation, with Amount and Merchant mapped.

If Shortcuts says the automation "contains no actions", it was saved before the action was added. Open Shortcuts › Automation, tap it, tap "Add Action", search "Cash Book", add "Log purchase", map Amount and Merchant, then Done. The full walkthrough is on the Apple Pay auto-logging page.

iCloud sync is not working

Check that the iPhone is signed into iCloud in the iOS Settings app, and that Cash Book is allowed under iCloud → Apps Using iCloud. Then turn iCloud Sync on in Cash Book's own Settings and restart the app. Sync changes only take effect on restart, which trips up nearly everyone who tries it once and gives up.

An amount looks wrong

Tap the transaction on Home, change the amount, tag, note or date, save. Totals, budgets and insights recalculate on their own. Nothing is locked after the fact.

Requests and ideas

Feature ideas get read. Email them, or send them from Settings → Feature request in the app. The useful ones describe the moment that annoyed you rather than the feature you think would fix it, because the annoyance is specific and the proposed fix usually is not, and that gap is where most of the good design turns out to be hiding. What happens to your data is in the privacy policy, and every release is listed on what's new.
