User Friendly but NOT really free

This app is very easy and it does work well. Ive never had it crash and my mac is certainly faster since installing it. There are in app purchases if you want the extras like App Shrinker or Memory Boost etc. Each add on is about 1.99$-4.99$. They should tell you that in the product description but they dont. That really bugs me. I would have bought a different one if I had known I would have to pay anyway. Over all it is user friendly and did speed up my mac without damaging any of my programs so I do like it. Just dont be fooled by the "Free" tag, its just not true!
