## Most critical reviews (7 lowest-rated)

### 1/5 — Poor

*2018-11-11, version 2.1*

Don’t bother all sizes are in imperial for a metric app this is rubbish

### 1/5 — Terrible

*2017-05-09*

Every size I need info on is not there, better just stick to the machinist handbook!

**Developer response:** Not sure what sizes you are looking for but all the most common thread forms and sizes are included
They are also clearly stated in the description on the AppStore
Sorry you bought something you didn’t need

### 1/5 — Inspector

*2013-05-28*

One of the worst apps. Would not allow you to change thread pitch when thread size has multiple pitches. Deleted it as fast as I put it on, was worthless to me.

**Developer response:** This app contains all the common threads with their associated pitches
It does not handle variable pitches

### 4/5 — Good

*2012-11-02*

Is very good but would be better if it showed internal bore dimensions and internal tread dimensions for NPT and BSPT.

### 5/5 — Great little app

*2023-07-23, version 3.0.1*

So convenient having screw cutting info at hand with just a few spins of the selection wheel

I’ve used this since it was first released and like the new look 

Loads of threads added but I mostly refer to the metric ones 

Just hope they add Acme soon

### 5/5 — Great app👍👍

*2019-02-15*

This app has provided everything I have asked it to.  It has more thread dimensions than I will ever use.  For a couple of dollars it cannot be beat. Also I do not like to soil my expensive reference material. With this app I can just give my phone a quick wipe down.

### 5/5 — Estimator

*2014-05-01, version 1.0*

If you are a mechanical engineer this app is a must
