### 2/5 — Does not keep standard settings

*2025-05-26, version 1.0037*

Since you generally need always the same conversions in your trade, preferences for standard settings would help. Every time you close the app, you have to prompt your settings again.

### 1/5 — Should have option to be in the header

*2024-12-03, version 1.0037*

useless to have the app on the dock - should have option to be in the header.

### 5/5 — 1000

*2024-10-17, version 1.0037*

GT

### 3/5 — Useful but could be better

*2023-12-04, version 1.0037*

Would be a lot more convenient if you could set your own default conversion. It always defaults back to miles/km and I always use it for inches/cm.

### 4/5 — Slight annoyance

*2023-11-03, version 1.0037*

I wish there was a way to change the default conversion when you open the app. I only use the mm to in and it would be nice not to have to change it every time. Otherwise no complaints

### 1/5 — Menu keeps popping up

*2023-08-22, version 1.0037*

Small bug or poor design. The menu keeps popping up when I click on it. It's annoying. Sometimes I would need to click the app when switching windows.

### 4/5 — Useful app.

*2023-07-09, version 1.0037*

Easy to use app, but could improve if the default unit on opening were to stay on the last unit you had used or to the one you had used most often. 
I often use to change cm to inches but every time I go into the app I have to change from miles/km to what I want - it’s just a bit irritating.

### 4/5 — surprisingly funcgtional and complete

*2023-05-07, version 1.0037*

It could do with an actual "help" meu,

### 4/5 — Muy bien app

*2022-10-03, version 1.0037*

Esta muy bien esta app, pero estaria mejor si te deja guardar tus opciones preferidas y no tener que estar buscando las unidades cada vez que abres la app.

### 3/5 — Great little app with one big annoyance

*2022-08-24, version 1.0037*

I love how functional and light weight this app is but it is REALLY annoying that it doesn't save which Units you were converting.

I nearly always need to convery inches to cm, and so if I was doing that last time that is what I want to do next time.  Unfortunately the app defaults back to Miles to km each time you open it so you need to go back in and change the units.

A small thing, but very annoying.
