## Most critical reviews (8 lowest-rated)

### 1/5 — It’s not working

*2023-07-31*

It’s not working.

### 1/5 — Not enough info can be entered

*2023-06-18*

Does not give enough options to calculate correctly 
You cannot put in head volume cc
I’m a little disappointed with this especially when you have to pay for it

### 1/5 — Garbage

*2021-04-24*

Don’t buy, useless app. Will be pursuing a refund.

### 1/5 — 1:38 compression ratio... I don’t think so

*2020-11-29*

I entered 302 specs at 4” bore 3” stroke and 8.206 deck height and it calculated at nearly 500hp and a 1:38 compression ratio..... yeah, this calculator is inaccurate, waste of money!!

### 1/5 — No stars

*2020-01-28*

Waste of £2.99. Does not use combustion chamber volume. Pointless.

### 1/5 — I want my money back.

*2018-10-26*

Can’t do anything on it.

### 1/5 — Would like a refund

*2018-10-23*

The app keeps crashing after 30 seconds of use do not use

### 4/5 — I wish I could have landscape

*2020-11-03*

That’s my only rub. And it’s not a big one.
