Touch RPN Calculator Customer Insights

1. As a realtor I use this app regularly and it has been great even with some pop up ads, BUT lately these Obnoxious Ads from Lending tree have been popping up and you can close the ad or use the calculator!!!! I ran an update for your app 2 days ago & it worked for 1 day no the stinking lendingtree ad is BACK & wont go away!!!!!I bought the computer programmer and advanced scientific apps before this single app came out and I'm able to use both with this new app ad free.

2. I like that developers can monetize their work product but seriously, when you have to be subjected to multiple full screen ads and play find the tiny close hot spot just to do a single calculation it has gone too far.The paid version now has ads.

3. The developer explains this happened when they consolidated the different versions in the app store into a single version with "flavors" and lost track of who had paid.

4. Of course the app didn't transfer to the new phone, because it is a "different app" although the look and work exactly the same and so is the developer's screen prior to the calculator screen.

5. I guess the memories about the reactions from customers that Epxx got that last time around with regards to the splash screen have purposely been forgotten.

6. Plus this has Financial app thrown in for free.Tried the free ad - supported version, and although the ads were mostly non distracting, decided to buy the no - ad Advanced version to support the developer.

7. If you don't use it for a couple of seconds, then it turns into a full screen ad that you have to press another button to go back to the calculator.

8. Splash screen is irritatingIf you are on a much older version you like, do not upgrade.

9. This is completely unusable garbage app!!I paid for this app, "Andro12C", in a previous phone, now it's called "Touch RPN calculator",.

10. !!!I have been using this app for several years and it's been Perfect, I didn't have to carry my HP12C with me, anymore.

11. I fixed mine by opening the app, pressing the "ON" button and choosing "flavor" as "Financial Premium".
