Yes it's free! Why? Well this was mostly createdly for my own purpose, but then I decided to extend to anyone else that might benefit from this.

As this is new, there is likely to be some fine tuning to be done, and hence, your feedback is payment enough!

Will it be charged in the future? Uncertain at this stage. There are some server running costs. One thing we can gurantee is that for anyone that signs up now during this free period, will have at a minimum the current features free for life as long as the same email address for sign up is maintained.
