### 3/5 — No decimal point feature on power field

*2021-03-29, version 3.0*

Please can you update this app so it supports decimal point input on power field on iOS. Otherwise great app for a well known company.

### 4/5 — Bit lacking

*2020-07-12, version 3.0*

Would be nice to enter amps into the cable calculator rather than just watts, would save another calculation.

### 3/5 — Decimal points

*2020-07-07, version 3.0*

Good app but doesn’t allow a decimal point to be entered for the load. So if you have an 8.5kw shower you can only enter 8 or 9. This may have an effect on what the cable Calc should be.

### 1/5 — Poop

*2019-08-31, version 3.0*

Doesn’t cover the majority of protective devices and when you enter details for cable calcs it goes into meltdown and can not confirm any suitable sizes 🤷🏽‍♂️ what’s the point...!

### 5/5 — 18th edition update?

*2019-06-12, version 3.0*

Great app, gives a quick calc to cable calculations. 
Is it getting updated to the 18th edition?

### 1/5 — Fail

*2016-08-11, version 2.1*

Options for cable runs doesn't include underground. Cable choice minimal. No help at all

### 1/5 — Don't waste your time.

*2016-03-28, version 2.1*

Hopeless calculator!

### 1/5 — .

*2015-11-28, version 2.1*

Waste of time downloading

### 1/5 — Failed to work

*2015-09-22, version 2.1*

Full of bugs, needs work!

### 1/5 — Poor

*2015-01-19, version 2.1*

Doesn't allow you to change the percentage drop.
