CasaTab
Tracks every cost of buying a house, down payment to furniture, with shared expense splits.
CasaTab logs every home-purchase expense across 14 categories, from down payment and notary fees to renovations and furniture, and shows who paid what when a partner or family member is invited to the same house. Its mortgage calculator handles fixed, variable, and mixed rates with Euribor, SOFR, or BoE base-rate tracking, extra repayments, and a full amortization schedule. Documents attach directly to expenses in a vault, and you can export everything as JSON or delete your data in one click.
