appkeep is a decision support tool for homeowners, designed to help them manage property maintenance and repairs using frameworks adapted from professional property management. The service provides a structured approach to evaluating what needs immediate attention, what can wait, and what the likely costs will be. It is currently available for homeowners in Finland, the Netherlands, and Sweden, with plans to expand to the rest of the European Union and then globally. The core function of appkeep is to give homeowners a maintenance plan that includes a multi year schedule, a record of past decisions, and a method for handling new issues as they arise. Users can input a symptom such as a boiler that stopped working or a crack that appeared, and the tool helps determine whether the problem is a minor repair or a major replacement. It also provides a mandate calculator, which allows the homeowner to set a budget ceiling in writing before a contractor begins work. The contractor is authorized to proceed up to that amount; if costs exceed it, they must stop and provide a written explanation before continuing. The service includes guides on how to brief a contractor, how to compare quotes, and how to assess urgency based on safety, environmental impact, and property protection. Typical use cases include responding to sudden damage like water ingress or a broken boiler, preparing for seasonal tasks such as roof or gutter checks, and making informed decisions about whether to repair or replace aging equipment. The workflow begins with describing the observed symptom and location, then checking the age and condition of the component against the home’s record. The user can then set a mandate cap or enter an existing quote to see if it falls within typical market ranges. The methodology and guides are publicly available for free, while the personalized system that runs on a specific house costs 37 euros per year, including VAT. The subscription renews annually with a 30 day advance notice and a 14 day cancellation period for a full refund. The service uses EU average hourly rates for trades, with a note that users should adjust for local markets such as higher rates in the Netherlands and Germany.
