I also have to agree with all of those who are pro Excel. Fitness trackers are great for long distance runners, bikers or professional athletes who really need to log mileage or hit a performance goal. For the general population that is looking to get healthy, I really recommend just keeping a journal whether on pen/paper or via spreadsheet.
I don't think tracking your steps, sleep, etc via an electronic device is the best way to get or stay healthy. The key being stay. So many people buy fitness trackers with initial enthusiasm for exercise and then burn out and the tracker becomes this device on someone's wrist that doesn't mean much. I think focusing on exercising consistently throughout the week, going to sleep and waking around the same time each day, and keeping a rough log of how many veggies you're eating provides much more impact.
If you're looking to give this as a gift to kick start someone who is sedentary, then maybe it's worth looking in to, but I personally don't like them (this is coming from a non-distance, avid exerciser).
