Awesome but ads are too much!


I absolutely love this app but the ads are too bothersome right now. At the beginning the ads were tolerable-a banner at the bottom, but recently the video and audio ads I have to suffer through before using the app have become too much! Get rid of the ad barrier and I'll give it 5 stars!

$.99 version

Renewable Energy Guru

To all of you frustrated with the free version of this app, it's time to pay $.99 for the add free version. The free version has been rendered useless by the adds invasion. Out of frustration I deleted the app. I have not seen any adds in the paid version so far.

Perfect app that was ruined


The old version of this was perfect; I used it all the time, daily. Now they've added ads that keep getting in the way, and pop up too frequently. I would pay for an ad-free version, but they don't offer one. And the ads keep getting longer, something that discourages me from using it to quickly double-check a measurement.
