I recently switched from BeMob to Skro and I'm glad I did. I'm absolutely loving Skro so far. The interface is intuitive, easy-to-use, and has all the features that you expect in a good tracker, plus some. I also love that the pro account doesn't limit you on the number of landing pages, campaigns, traffic sources, and offers as BeMob does and it's $10 less per month! Also, the support has been amazing. It's fast and thorough. I don't think I've waited more than 10 minutes to get a question answered.
I highly recommend giving Skro a test drive!!
