• Dark mode — the app now follows your system appearance. The bill you send tenants stays on white paper, so nothing changes on their side. • Titles and margins now line up across every screen.

• A recurring fee per room (Pro) — parking, rubbish, whatever you charge every month. Set it once on the room, adjust this month's amount while you read the meters, and it lands on the bill • Money paid in advance is no longer lost when the month closes — it carries as credit and comes off the next bill • Rooms you have not read yet still count toward what is left to collect, so arrears stop disappearing from the summary • Moving a tenant out now records what they still owed • A discount entered on a room that was never billed no longer applies itself the following month • The Excel workbook adds up: brought-forward, received and outstanding columns, so every row ties back to the bank • Erasing everything now asks you to save a copy of the whole book first, then holds the button for fifteen seconds • Erasing also clears the archived history — a past tenant's details no longer survive it • A new app icon

• Buildings (Pro) — group rooms by property instead of one flat list • Record partial payments; what is left carries onto next month's bill, and the QR asks only for what is still owed • Choose your messaging app — LINE, WhatsApp, WeChat, Telegram, KakaoTalk, Zalo • Undo closing a month, meter readings and payment status included • Old history is no longer deleted — it moves to an on-device archive and still reaches the Excel export and your backup • Metering warns clearly when a reading is below last month's, and lets you correct the starting reading on the spot • Two phones no longer overwrite each other — the book merges room by room • Five new languages: French, German, Spanish, Portuguese (Brazil), Russian — 15 in total

• Add a discount or an extra charge to one room's bill, with a note the tenant sees — it applies to that cycle only • The meter screen shows last month's reading as the placeholder, instead of a 0 that suggested typing the difference • Starting meter readings are required when adding a room, with a warning when a baseline is 0 — so a first bill can't charge the meter's whole accumulated reading • Buttons respond across their whole surface, not just on the text — the meter numpad most of all • iPad: the selected room in the sidebar is readable again

• Lease management: set start–end dates and photograph lease documents (kept on your device) • Home screen warns about leases expiring soon • Move-in / move-out flow — move-out archives the tenancy for your records • Per-room history & stats

• 10 languages with an in-app language switcher • New multi-country payments: VietQR, KHQR, and upload-your-own QR • Choose your currency and country default rates • UI polish and bug fixes • New! Pro unlocks unlimited rooms (free up to 18)
