Best most reliable app I have and I use it almost daily

I have had this app I think since it was developed. I used it for free for years. I bought because this is possibly the most reliable app on my phone. It is definitely a deal for $6, and it’s a family share app.

An added advantage is this is a small company, and small businesses should always be supported. When they make an excellent product that replaces several that charge up to 4-5 times more for one or two options out of the many this one does it is a no brainer.

Best app purchase I’ve made.

Went Pro!

I have used this app for years and just paid for the pro upgrade. Do you know how unusual it is to use an app for years and not switch to a new-kid-on-the-block? I have no problem supporting a single pay app (no subscriptions for me!) that has proven its worth to me. The pro version loses the ads (a minor annoyance, but an annoyance just the same) and comes with a currency converter and large digit (font size, not number 😁) app. This app is rarely updated because it works—done right from the beginning. Thank you, Alan.

Not only is this App tremendous in what it does, when I had a minor issue with it operating on my iPhone - an issue that turned out to be no error on the part of the App and it’s programmers - I was graciously, and IMMEDIATELY assisted until it was resolved.

The ads on the free/Lite version aren’t really any problem, but like another reviewer said, I chose to purchase the Pro version in order to support what is such an impressive App that I felt it deserved to be paid for.

I can’t recommend this App enough!
