## What is Stars and Units?

This app helps travelers to or from the USA with the conversion of the most important units 
for distance, weight, volume and temperature.

During development, particular emphasis was placed on simple and fast operation:
Simply tap in the field with the unit to be converted and enter the value.
All the related units are converted and displayed immediately.
    
There are no menus, no select boxes and only a single screen in this app.

Of course, there is no advertising, no subscription, no in-app purchases and no personal data is collected or recorded.

When we rode our bikes from Mexico to the USA in early 2025, we were immediately confused by the different units.
We were delighted to see a sign saying “Kingsville 30” and only later realized that we were talking about miles and that it was still almost 50 km to Kingsville!
At the hotel, the air conditioning showed 68 degrees and we had no idea what we had to set here to get to our 24 °Celius.

Of course you can find pages on the Internet for the conversions, but that is cumbersome.
An app would be better. 
There are a whole bunch of conversion apps in the stores, but they are more for school and university.
They can convert every conceivable physical unit into every related unit.
However, they need several screens, menus, select boxes etc. to do this.

The normal traveler does not need most of these conversions at all.
That's why I wrote this little app myself, which helped us again and again during our stay in the USA.

### 4/5 — Good but can’t enter - Degrees in Celsius

*2025-01-12*

The app is good but I couldn’t find a way to enter minus Symbol as only the number pad appears

**Developer response:** Oh, you're right. The minus button is missing on iOS, thanks for pointing that out. I will fix this problem shortly with an update.
