### 5/5 — Great app, time saver

*2026-10-05*

Flint is a genuinely useful app for heating engineers. It saves a lot of time hunting through manuals when fault finding or looking for boiler-specific information on site.

What I particularly like is that Wes is clearly putting the work into developing it properly and listening to feedback from engineers using it in the real world. The coverage is already impressive and it keeps improving.

Definitely worth having on the phone if you work across different boiler manufacturers.

### 5/5 — So handy

*2026-10-04*

So I’ve been using this app quite daily, actually, as it gives me all the manuals in the palm of my hand, and if there’s something I don’t understand in it, I can get it to explain it for me using the AI and also can retrieve anything from the manual. Not quicker than I can find it. as well as having ordered normal standard stuff accessible right in front of you, it’s a real time saver.
