I love this watch: [https://a.co/d/cehxA9F](https://a.co/d/cehxA9F) Xiaomi Smart band 9. It has a really great battery life (\~20 days) and it's not as expensive as the comparable fit bit options. I bought a custom flexible band too and only take it off during showers.

Jusqu'ici j'avais un Redmi Smart Band Pro et il assurait le suivi de la natation (il détectait même le style de nage...) Mais comme il commençait à fatiguer (sutout les attaches du bracelet), j'ai pris un Xiaomi Smart Band 9 Active (50 modes de sport) Hélas, la natation n'apparait même pas dans la liste des activités sur le bracelet... Je vais sûrement utiliser le mode Entrainement pour le suivi Je suis un nageur occasionnel donc ça me suffira Le Smart Band 9 "classic" a 150 modes de sport donc j'imagine que la natation en fait partie

Perso j'ai une xiaomi smart band pro 9 et pour le prix (60€) rien à dire, bonnes fonctionnalités sportives, très bonne autonomie, c'est compatible avec strava (il faut synchroniser mi fitness et strava), et surtout il y a un gps intégré d'assez bonne précision donc le téléphone est moins indispensable à avoir sur soi. Le gros défaut c'est justement en natation où il ne calcule pas le temps de déplacement spécifiquement, mais divise la distance sur le temps total d'activité pour calculer le temps au 100m, donc ça donne un temps bien trop élevé

I'm using a Xiaomi Mi-band 9 to count laps. There's more, but it counts laps fine, is cheap and has a battery that lasts me a week.

Mi Band 9, The best watch super cheap but tracks everything I need: heart rate, distance, altitude, blood oxygen, and more. The best part is the battery lasts 6 days. I love it.

Since the Garmin and Fitbit were not enough for you, your expectations might be too high. Sleep tracking would never be very accurate no matter how expensive the watch is. I have used some cheap (less than 100) fitness trackers and so far Mi Band 9 Pro works well enough in my opinion. It does all you want (HR tracking, sleep monitoring, high/low HR alert) and also has basic smart features such as notifications, GPS, weather app, timer, alarm, compass etc. Mi Fitness app is easy to navigate. It does not fail to detect my actual sleep, but thought I was sleeping while I was just resting and not moving my arm for few times in the past several months. You can delete the fake sleep session on the app so it was not an issue in my opinion. The only slightly annoying thing about its sleep tracking is that it calls sleep shorter than 3 hours 'nap' and does not record sleep stages. Overall I am happy with my purchase.

Xiaomi makes a decent smartwatch on the cheap. The smart band 9 is solid if you want sleep tracking/fitness stuff for less than $60.

I know that Greg Mairs uses Zoop. Personally, I use a Mi Band 9. It lasts for a couple of weeks and heart rate is quite accurate +/- 3bpm. OnePlus has a watch that tracks shots played and so forth
