## Most critical reviews (7 lowest-rated)

### 1/5 — Buggy

*2015-02-21, version 1.1*

Worked first time I used it, now either loads with all fields empty or hangs saying "syncing". LinkedIn login has a mandatory field for contact details that is a drop-down (JM country), which is empty when you press it. Therefore unable to log in with LinkedIn. Shame, could be good.

### 1/5 — Doesn't work

*2015-02-10, version 1.0*

Just hangs saying "syncing". Nice idea but please sort this out! Uninstalled pending update hopefully...

### 5/5 — Useful App

*2018-10-31, version 2.1.1*

Nice new look. Love the custom chemistry option too!

### 5/5 — Wow!!

*2015-02-10*

Easy, Neat and Powerful.

### 5/5 — Does exactly what it says on the tin!

*2015-02-09, version 1.0*

Makes life a lot easier to have all this in one place.

### 5/5 — Brilliant!

*2015-02-09, version 1.0*

Very sleek and professional looking app. Can see this will be incredibly useful.

### 5/5 — Guide

*2015-02-07, version 1.0*

Brilliant! Extremely useful
