Inspire 2

My inspire 2 is the best Fitbit I’ve had with which I’ve swam a few times and it has best water-lock feature I’ve personally experienced. You can press both sides any time (even and especially useful AFTER starting a workout) to engage it with. I couldn’t speak for your specific needs though as I basically just swam and didn’t check what it logged. I’ve had charges 4 and 5 and sent the inspire 3 back because it lacked this key feature which is essential for me.

Mine too! And the battery lasts like two weeks before I need to charge it

I currently have an Inspire 2 and overall really like it for step and sleep tracking, just that the screen is hard to read. There's a sale going on for Fitbit's but having mixed doubts if Google is trying to kill off the brand or not. I read they want to come out with new models in 2026 so is that a sign they don't want to get rid of the brand and support existing customers?

The Fitbit Inspire 2 is like $10-20 on eBay these days, depending on what sort of condition you want (I'm going to scuff the thing no matter what, so I have low standards 😝). It's a seriously great little device. It's unobtrusive and waterproof, the battery lasts forever, it tracks heart rate and sleep in addition to steps, and offers nice little movement reminders if you so desire.  For *my* bouncy gait, the step tracking has been accurate in every test I've done, even when pushing a cart or stroller. My wife's experience is different: She tends to glide rather than walk, and sees more undercounting than I do. 

I agree about the Inspire 3. I've had mine for several years and use many of its features every day. I think it tracks steps better than any of my husband's Charge models (3,5,6). I liked my Inspire 2 and bought the 3 only because I could swim with it. I gave my Inspire 2 to a friend and she is still using it.
