Spam, scam
Well they are supposed to have a HRV functionality. Their site recommands Elite HRV. Their support (beit sales or technical) is just incapable to provide specifications of Sleepon HRV metrics or charts, which are just useless). Oh well, around 6 months of sales ads spam, repeated announcements about a 3.0 new APP to push these sales. Was launched 15th may, they said. 27th may and what a surprise : no new APP in the Stores. Update 10/10/2024 - I had given Sleepon 3 App a try early august 2024. Same problem. HRV has tons of metrics : the metric used by Sleepon remains not speficied, not a word in the manuals, FAQ, or in the App/Web dashboard. A 20 USD chinese watch has Poincaré or Lorenz plot, RMSSD metric, in-App HRV guidance.
