my sister loves her lily 2 active - very fashionable and really good looking but can work for fitness too. The other pro over the lily 2 is the much longer battery life (almost double) and added buttons. so its not just the gps. Though it is slightly larger than the lily 2.
all day wear no issue and she lives in a very hot climate so no issues with sweat etc. Took a bit for her to get used to wearing at night as didn't used to wear a watch to bed and its her first smartwatch. But yes its tiny and light so no biggie.
Yes and you can sync another app in the Garmin connect to log food. I récommend Garmin Lily 2 Active with GPS.
Garmin Lily! It’s small and the face is round. It looks much more like a regular watch than many fitness watches. I love mine!
Yes! Minimal charging time once a week. I’ve had mine for 5 years now! Tracks sleep well I think.
Another vote for the Lily! I’ve had mine for 2 years now. I have both brown and black leather straps for it that I rotate depending on outfit, as well as a silicone band that I wear when I’m actually working out and getting sweaty. ETA: the battery lasts me about 5 days. Charging only takes about an hour and a half. I don’t wear mine to sleep, so I can’t speak on sleep tracking.
Definitely don’t get the Lily or Lily 2. The Lily 2 Active does have built in GPS so it might be okay for your needs. However, I had it for about 7 months and changed to the Venu 3s which is 100% better. The Lily series is a basic fitness watch that is not worth the price when there are other watches at the same price point that give you way more features. I also have small wrists and the slightly larger size of the Venu 3s if just fine for me and honestly not noticeable when wearing it. I’ve been using Garmin Pay on my watches over the years and it works great. (Saw someone said it doesn’t work for them, but I’ve never had an issue) If you haven’t already, you can compare watches side by side on Garmin’s website which is very helpful! But I’d recommend a watch in the Vivoactive, Forerunner or Venu series.
I can't comment on the ring, but I can recommend Garmin lily for sleep tracking. I wear a Garmin Lily during the day and for sleep, and switch to my Garmin Forerunner 745 for workouts. I like that the watches talk to each other through Garmin connect so I never miss steps or double count steps.
\+1 got Garmin. I've been using Garmin products daily for nearly 20 years and I continue to be happy with the products. I wear a Forerunner 745 during exercise and a Lily the rest of the time.
I've been a Garmin user for ages and I love the products. Bit pricier upfront, but no need for monthly subscription for good features. I wear a Garmin Lily for daytime and sleeping, and then use a Forerunner when exercising.
