Objekatus
Deine eigene Hausverwaltung
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Utility bills, the Anlage V tax schedule, rent increases, dunning and more for private landlords in Germany. Transparent, on-device.
Objekatus is your own property management in your pocket. You manage your rental properties entirely yourself, from tenants and receipts to the finished statement and your taxes. No complicated management software, no additional account.
Everything stays on your device and, optionally, in your private iCloud. No server, no tracking, no sharing. If you like, lock the app with Face ID, Touch ID or your device passcode, and Settings honestly show whether iCloud sync is active and when it last synced.
EVERYTHING ABOUT YOUR PROPERTIES
Create your buildings and apartments, record tenancies with their period, contracts, receipts and meter readings. Scan receipts by photo with text recognition. The dashboard shows deadlines, open arrears, liquidity and costs at a glance, and "What is missing?" points out gaps.
TRANSPARENT OPERATING-COST STATEMENTS
Allocate costs by your allocation key (living area, occupants, consumption or units), cent-accurate and with a transparent formula for every line. Heating costs and the CO2 share come from your metering service's statement; consumption-based billing also works with your own meters and readings. Export the finished statement as PDF or CSV.
MAKE TAXES EASIER
Objekatus prepares the German Anlage V tax schedule from your income and expenses, including a depreciation (AfA) assistant and the distribution of larger maintenance expenses per § 82b. As PDF or CSV for your tax return.
RENT AND DUNNING
Rent increases, index and stepped rent including a ready-made letter. Payment reminders and dunning letters with deadlines and default interest as PDF. On request, the § 35a certificate for your tenants.
NEW: RENT PAYMENTS FROM YOUR BANK STATEMENT (BETA)
Import your bank statement from online banking as a file (CAMT.053 or CSV). Objekatus compares the incoming payments locally with your tenancies and suggests which payment belongs to which tenant, most reliably via the stored payer IBAN. Only what you confirm is recorded; all other transactions are discarded and never stored. No bank connection, no credentials, just a file.
CONTRACTS AND PROTOCOLS
Create leases and terminations from your data, sign directly on the device and file them as PDF. A handover protocol for move-in and move-out is included.
DEADLINES THAT REMIND YOU
Local reminders for the 12-month billing deadline, termination deadlines, open receipts and the annual meter reading. All on your device only.
RENTED CONDOMINIUM
For a rented condominium, capture the HOA (WEG) annual statement and split it into apportionable, deductible and reserve.
ONE SUBSCRIPTION FOR YOUR WHOLE PORTFOLIO
Recording and viewing is free, and you can try everything on the included sample data. For the full statement, exports and the Anlage V you unlock your portfolio with a subscription. The tier is based on the total number of your units, monthly or yearly. If your portfolio grows, the app guides you to the matching tier. If you sell a property, archive it and downgrade.
IMPORTANT
Objekatus is a calculation aid and no substitute for legal or tax advice. You are responsible for the correctness of your statement. Check amounts and allocation before sending.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Version 1.2 makes everyday work easier and the app even more trustworthy:
• Bank statement import (beta): read a statement from your online banking locally (CAMT.053 or CSV). Objekatus suggests which incoming payment belongs to which tenant; only what you confirm is recorded. Already recorded payments are recognized automatically on re-import, you can assign the rent month per entry, and duplicate or diverging bookings are made visible instead of being recorded silently.
• Payer IBAN per tenancy: store the IBAN your tenant pays from and Objekatus matches payments with high confidence.
• Heat pump and heating without a metering service: choose the new heating type "central without metering service", allocate heating costs in line with the German Heating Costs Ordinance (50 to 70 percent by consumption, the rest by living area), and split hot water with the Section 9 assistant.
• App lock: protect Objekatus with Face ID, Touch ID or your device passcode, with an optional grace period.
• iCloud sync status: Settings honestly show whether sync is active, when it last synced, and, if something is stuck, in which direction.
• Payments show their origin, and the FAQ and privacy policy have been expanded.
• Calculation and checks were sharpened in many places: default interest accrues per open claim from its own due date, consumption from vacancy periods appears as the landlord's share in the statement, and heating and CO₂ findings now appear in English in the English app.
• Handling: the keyboard can be dismissed everywhere, titles and the search field are no longer truncated, and the rent-step overview is archived deliberately via the "Issue overview (PDF)" action.
