In my informal testing, the heart rate sensor isn't quite as snappy as the Fenix 5 Plus or Apple Watch 4's sensors, but it's accurate enough that I'm confident in its readings. Like those devices, the Instinct can also display notifications from your phone. Though if you're used to being able to do stuff with your notifications like I am, suddenly not being able to do anything with them can take some getting used to.
Loads of research demonstrates people who log everything they eat — especially those who log while they're eating — are more likely to lose weight and keep it off for the long-haul. Start tracking on an app like MyFitnessPal when the pounds start sneaking up on you. It'll help you stay accountable for what you've eaten. Plus, you can easily identify some other areas of your daily eats that could use a little improvement when it's written out in front of you.
getfit is great in that it is pretty satisfying to see how my physical activity measures up. It also prompts me to kick myself when the goals are not met. The different elements that allow the community to get to know MIT better (e.g., the tunnel walks) are pretty cool. It provides another avenue for me to connect with my friends, and I think getfit is a great program to enhance wellness at MIT.
