Horrible. Upgrade this junk.

First of all, as was written before, the free version only allows ten entries before forcing an upgrade of 99¢. Then, when you upgrade, the old contraction times and intervals between the contractions are not carried over to the upgrade. When you actually start using the upgrade, it looks NOTHING like the free version. While the graph is nice, its useless because the interval timer, which is the most important aspect for the app, does not reset when stop and start are hit. Instead, it begins the next interval time at the end of the last contraction. A waste of a buck and until there is a major upgrade to this piece of garbage, I want my money back!
