Good, but missed an opportunity

I just bought this app. It seems well-designed, and I like the sharing and PDF options. Those sold me.

But when I used the app, I was surprised that the sound effects were so lame. I expected a traditional adding machine sound, but instead it gives me a little "beep" like a Casio watch.

If you are going to use realism in your user experience, as this developer has done, then complete the picture by providing realistic traditional sounds.

Happily this can be corrected with an update, and I encourage the developer to do so. It should be easy to get a recording of a real adding machine in action.
