I unknowingly had the comma separators for thousands set to Indian mode. I thought it was a developer error. He replied immediately and explained how to set the format to american. All is well. Also, if the app is uninstalled, it can be reinstalled, even on a new phone. This is a great app, and even better support. Thank you. This app is one of my fundamentals.

Change the decimal separator in Settings (ON key). The 10,00,000 thousand separator scheme is the Indian mode, change to American or European. The purchase is kept even if you reinstall the app, replace the phone, or have more many phones under the same Google account.

If you are on a much older version you like, do not upgrade. I inadvertantly updated this once outstanding, polished app to the advertising layden monstrosity it has become. If taking values from another app, you are presented with an unclosable ad for each number entered. 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.

Love this program. Would give it 5 stars. Even bought the pro version. However the damn splash screen is back. Have a way to turn it off or just delete it. I don't want to look at that stuff, especially when I pay for an app. 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. 3/4/2020 - I did, scientific premium, and that's how it was when I wrote the above. Splash screen is irritating

If you configure to a purchased flavor, the splash screen goes away fast (about the time the app always used to take to start up).
