What’s New

Version 2.0.0

In this version we've freshened up the interface throughout and completely redesigned the Stamp Duty section.

We also made a few other improvements;
- there is now a legend at the bottom of each comparison page to remind you which mortgage the colour coding refers to
- you can now tap on the Stamp Duty card at the bottom of a scenario to navigate to the Stamp Duty tab where you can see the tax breakdown
- we've improved the deposit picker when creating or editing a mortgage to help you easily select a percentage of the property price

Great little mortgage tool!

A cheap and cheerful mortgage tool for the same sort of price you will pay for a sausage roll these days!

This slick app is really well put together and offers a range of tools offering stats/data about how much a mortgage may cost. Looking forward to see where it goes.

Useful under-realised tool

A fantastic tool to have in your phone. Simple to use, clear, concise with plenty of supporting information.
Cannot believe more people have found and used this app. #underpromoted
