Older paid version included currency converter too

I have been using the paid version of this app since 2012. I loved it when they added a new feature with currency conversion about 2 years ago .Today my app auto updates and suddenly the currency conversion feature is a subscription. My pro version had scientific, basic and currency conversion all included. Now I have to pay a fee for the same feature I have been using all along.

Developer Response ,

Thank you for reaching out to us with your feedback and our apologies for the caused inconvenience. The last update should have all the functions back in the app (for free of course).

Again our apologies for the inconvenience.

iPhone X problems

I upgraded to the ad free version of this app. It looks great, and I would love it, except that there is a serious recurring problem I’m having due to the app’s design clashing with the new gesture based interface Apple introduced with the iPhone X. Very often, when I attempt to exit the app by swiping up on the bottom of the screen to return to the home screen, it results in an inadvertent press of either the decimal point or the “+\-“ button on the calculator. This is very annoying. I like the full screen design of the app, which takes advantage of the iPhone X’s screen nicely, and I believe all that needs to be done is an adjustment to make inadvertent key presses less likely when a user swipes up from the bottom of the screen. Please fix ASAP. I want to keep this app. Thank you.

***UPDATED REVIEW: Still waiting on that promised update that will bring back all of the Holiday Themes I paid for?!

When I first paid for this app their were tons of Holiday Themes available. I used to love that! It was an original concept! Then they updated it, and all of those themes were gone. I contacted support and was told I would have to wait until the holidays rolled around to start collecting them again. Well...It’s Halloween time and there’s no themed calculators like last year. There used to be about 5 themes per holiday to choose from that were awesome! What a bummer! Now this is just a regular calculator app with different colors, very boring and more of the same.

Developer Response ,

My apologies for this inconvenience, it appears there was a miscommunication about the holiday themes. We are now in the process of releasing the version that fixes the problem with the holiday themes, which I thought was already released. With this version you should be able to get all the themes again during the holiday and unlock them permanently by selecting them during the holiday. This should be available within the next few days, and you'll be able to select and permanently unlock the Thanksgiving themes soon.

Again, our apologies for this inconvenience.
