Every time I open the app, it starts with a 0 that doesn't disappear when I start entering numbers. Unless I specifically delete it, it just adds a 0 to the end of whatever number I put in, effectively multiplying it by 10. Extremely annoying and completely pointless. Probably easy to fix, too. They just don't.

This app would probably receive 5 stars if it didn't regularly clear the current figures on the screen. I use this app to keep a running tally of my pay over the course of a week. The app randomly erases my current tally. I save my data at the end of each day, so that feature is helpful. But every day, when I add my new data, the app randomly erases what I've added. So, I have to go back to my saved data and start again. It's extremely frustrating. Please fix it!

I love the app and use it often. we all know it needs more options in the conversion section, like currency and power/torque, etc. Since my phones last update, my cursor is on the left side of the 0 instead of the right. So, any numbers you type in, that 0 stays there in your calculation unless you clear it every time you use the app. Edit: I just uninstalled and reinstalled it, and it works fine now. I did lose all my recent calculations.
