I like that it's free to use, and I love how easy it is to get started with. I also love that it has so many different options for data collection. It allows me to create custom dashboards with my own stats. The only downside is that sometimes there are bugs or glitches in the product which can be frustrating. I highly recommend this software to anyone who wants a great tool to keep track of their goals and progress. I have been using Tanzle for a few weeks now and I am really happy with the results. I have noticed that I am making good progress towards achieving my fitness goals.
