Features for outdoor, especially for hiking, it hasn't needed to connect to gps in haylou solar lite 2 when it started, so I can't afford data that I need to know like maps of course. In the apps just provide running outdoor, walking outdoor, and cycling outdoor, just that, there's no more sports I can't find in the apps when I need to use gps for my sports like hiking.

I am a user of the Haylou RS4 Plus. I would like to suggest an improvement for your breathing exercise feature in the next update. It would be a fantastic experience to perform the 4-7-8 breathing exercise clomp if the 'hold' phase had the same vibrating sensation that is felt during inhalation and exhalation. Adding this vibration feedback during the breath-holding phase would make the exercise much more immersive and effective. I hope you will consider this suggestion in the next firmware.

Excellent app! It connects to my smartwatch quickly and works smoothly. The interface is clean, user-friendly, and easy to navigate. I can easily track my daily activities, heart rate, sleep, and workouts. The syncing is fast, and the app has been reliable so far. Highly recommended for Haylou smartwatch users!
