Most money apps want eleven fields before they'll let you save anything. LemonBook wants one. Tap Money Out or Money In, type the amount, done. Merchant, category, date, note, receipt — all optional, all addable later. The point is that you actually record things, not that you record them perfectly. SIMPLE BY DEFAULT - Two taps from opening the app to a saved entry - One detail is enough — an amount alone, or just a name, or just a photo - Money in is mint, money out is coral. You can read a month at a glance. - Come back and fill in the rest whenever you feel like it SAY IT NOW, FILE IT LATER "Hey Siri, capture an expense in LemonBook." Siri asks how much. That's the whole interaction — no unlocking, no opening the app, no choosing a Book while you're holding a coffee and a receipt in the same hand. The amount lands in your Siri Inbox, which is a holding area rather than a Book. Next time you open LemonBook it's waiting on the Today tab, and you decide where it belongs. Nothing gets filed somewhere wrong because you were in a hurry. It's the same idea as the rest of the app: capture now, organize later. Voice just makes "now" faster. YOUR LEDGER, THE WAY A LEDGER SHOULD WORK - This month, last month, this year, or everything — with a running net - Search merchants, categories and notes - Month-by-month sections, so a long history stays readable - Categories with their own colors, or no categories at all - Loose ends — a quiet list of entries still missing a detail, if you want it PRIVATE BY DESIGN Your entries sync through your own iCloud account. LemonBook has no server, no sign-up and no login — there is no account for us to lose. Nothing you write is sent anywhere else, and no AI reads your receipts. Sync is included for everyone, free and Plus alike. LEMONBOOK PLUS — one purchase, not a subscription - Unlimited Books — keep business, personal and travel apart - Attach receipts and PDFs to any entry - Export to CSV, or a PDF packet for tax season - View several Books together, or merge two into one - Richer summaries LemonBook Free is not a trial. One Book, unlimited entries, unlimited categories, full search and filters, Siri capture, and iCloud sync — all yours, permanently. Plus is there for when your little book grows. Made by IMPLEMON.
