Questions, answered.
What kind of web work does 12F ApS take on?
Websites and web platforms for Danish businesses — marketing sites, customer portals and the tooling behind them. 12F designs, builds and hosts the whole thing, so there is one point of contact rather than an agency, a developer and a hosting provider.
Do you only build iOS apps?
No. Apps are the largest part of the portfolio — 13 are live on the App Store — but 12F also builds for the web: client websites, and its own web platforms such as Billederapport. The apps are listed on the Apps page; web work is listed here.
What is Billederapport?
Billederapport is 12F's own web app for photo reporting — tradespeople, inspectors and damage assessors photograph a job, mark up what matters, run a checklist and send a branded PDF report to the customer before leaving the site. It works without a signal and syncs later, and the data is hosted in the EU.
