A Must Have App

I have used the free version of this app for years now. The free version is very well done, small ads that don’t get in the way. No issue with bugs or crashing in all the years I have used it.
I only recently bought the full version for one reason, to support this company for a creating a tool I use weekly. Very user friendly UI, all around great app. I literally haven’t found something I do not like about it. Thanks for creating a solid product.

Outstanding Resource!

This app has been a blessing for my family and me for years. We've traveled in Europe and needed multiple currency, distance, temperature and weight conversions. In The States, I'm still using the app to convert volumes and lengths. I just found the time conversion tool that would have been a great help when calling friends and family at home. I've had no problems with functionality or navigation. With the frequent updates, this app is a keeper! Thanks!!

Much like earlier review by Tamaseu - I just purchased Pro version of this app literally just to support the company! This app is amazing, easy to use, never have had an issue or crash with it, fast, accurate, and many more positive adjectives. I use this all the time for so many things but especially the data conversion because I work in IT Support. Put your money where your mouth is sort of thing - one of the best apps I’ve ever owned!
