I own the Pebble, and now the Pebble Time through Kickstarter for about two weeks. I love it, use it for MapMyRun walking daily with the ability to voice reply (text conversion) to Messenger and texts while I am out. I switch music and monitor email, too. All with my phone in my pocket. The apps and watchfaces are plentiful and growing daily. Time Line keeps my calendar and appointments available with reminders. Plus I have gone 7 days on a charge, and that is while still tinkering and playing more so than I will be as I get everything set up (like one might expect), so more than a week will be my normal time between charges. Recharging takes less than two hours. It is waterproof! So I don't worry about sweat and rain, or even swimming with it on. There are more features than I will ever need, or use, so it is perfect for me. I have dressed it up with a bezel cover and clear lens protector, plus new watch band to match. And I can change it as I desire with alternate bezel skins since they peel off and watch bands that attach with standard 22mm pins (the installed band has a quick disconnect pin, too). The watchface color choices also can be set to match your bezel and band colors, too. I use my PebbleTime with an android phone, but it also works with iphones. It is light weight, and hardly noticeable to wear. The e-paper display stays on all the time, but a back light will show automatically in darker conditions to provide adequate viewing with a wrist flip or by installing the Backlight app like I have done and use. See my blog, updated daily at http://pebbleusers.blogspot.com/ for pictures and more details! I have no connection with Pebble other than as a customer and wearer of the watch, but I love it and the excellent customer support they provide. Which, for me, is a big plus! If there are ever problems you can count on them to be there for you. I look forward to the future smart watch bands, too. These devices will expand the functionality of the Pebble Time and provide future needs and purpose. News is forthcoming every day and this is what makes Pebble an exciting company and excellent watch choice.
