As far as keeping track of information online and having it compared over time is concerned, this site is not only effective but also quite original. You see, not only does RhythmData let you have information tracked for as long as you might need, it also lets you have the data that you’re storing compared with any other indicator you want.
Work hours by job, payments by clients, sales calls by prospects, reservations by property… RhythmData lets you keep track of all that and more. All you have to do is to submit the name of the first item to have compared for the relevant table to be created. This table will be editable from any device that can access the Internet, and you’ll be able to add new data the moment you have it. And this is great because it minimized the risk of you failing to add it afterwards either because you’re too tired to do it at the end of a long day at work, or because you get caught up doing other things.
RhythmData accounts cost nothing. If you think this is a service you could clearly get something from, just sign up for an account and start graphing whatever your job or your hobby dictates you should track.
