• 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)
