You need a tracker - complexity (new tool & I am a newbie)
Tracker costs money - budget (I have not paid a single penny, I am a newbie).
These are the two biggest issues newbies have with the trackers.
And, they want to avoid trackers.
In the market, there are loads of trackers, then why BeMob?
a) It's free to use up to a certain limit.
b) It's as complex as any other 100% paid tracker, not even a bit extra.
c) You are a free user, but you still get support. With the support, the learning curve is not as steep as it can be when you are on your own.
If you cross the free limit, it means you are making money; why not pay for the tool, when you are making money.
