This is by far the best Tip Calculator I’ve seen. It’s perfect in every way… except for one thing. The annoying adds. I noticed many complaints about the adds in the reviews, and couldn’t help but wonder why Tim O’s Studios dosen't take notice and come up with an add free paid version. The only reason I can think of is maybe there’s a much bigger profit in a free app with adds than a paid app without adds. So you’ve got to ask yourself, what’s really most important to Tim O’s Studios? Consumer satisfaction or the bottom line?
