When are you going to update it for the latest IOS for IPhone , class app but need to get it to work for the update

### 4/5 — Gas rate & heat input calculator

Good app, nice layout, works well, good colour contrast. 
Would like results slightly larger to save getting the spectacles out & maybe list CV's on info page for Propane & Butane gases to save looking them up.

I'm a service engineer and use it all the time! I've tested it a few times by doing the math and it's spot on!
