GPS coordinate converter - Interview with the developer of a fantastic app

Did you have any prior development or coding experience?

Coding has been my favorite hobby since I first got a 386 computer.

What was the most challenging aspect of developing mobile app?

As the coordinates and standards vary from country to country, it was hard to know which GPS coordinates were common and which functions were essential.

Minkyu Ryoo is the chief developer of the Smart Tools Suite and his company, "Smart Tools Co.", has the No.1 Android toolbox app that has sold over 1 million paid apps.

Name a few of your favorite apps and reason you love them.

Backgrounds HD (Wallpapers) by OGQ. An old friend of mine developed it.

How long have you been working on this app?

Most of the development was completed and released within a month. It took twice as long to get feedback and update it after release.

What need of the user did you have in mind when developing this app?

There were many requests for coordinate conversion by users of my compass app. I found GPS coordinates were used in more fields than we would expect.

In what way do you think your app is better than similar apps on the market? Please describe in detail what innovation you think you bring and what you are proud of in your app.

At the time of release, there was no app that converts UTM and MGRS coordinates because there was no open source. However, I was able to develop it easily with the library made while developing the compass have released 20+ Android tool apps that have similar themes and interfaces. Users who have used one or more of my apps once can easily use all the other apps as well.

What are your future plans and expected features of the coming new versions of this app?

I'm going to add more coordinate systems that are used a lot in Europe. I'm considering the function to share results.

Assuming new users of your app are reading this page. What do you want to ask them to do (contact you about X, Share the app, etc.)?

Coordinate conversion is a somewhat specialized field. Your feedback is very helpful.
