Not sure how to contact company except to write this review!!! Here's hoping that somebody will contact me!!! ### ⭐⭐⭐⭐⭐ Nice Fitness Watch (app version used 2.9.19) *by J***K on Reviewed in the United States on August 27, 2016* The watch is good. I have read some users wanting to change the time from military to normal. It is through the Hplus Watch App version 2.9.19. The new version 3+ has issues the older version of App is good.It supports, time, heart rate (real time via the old App), steps taken (realtime), calories burnt, notification alerts from mobile calls, messages, distance travelled, calories. Use the old App 2.9.19 ### ⭐⭐ Buy cheap, buy twice! *by A***R on Reviewed in the United States on October 12, 2016* Good points. Cheap, comfy, looks good. Bad points, cannot read the screen in bright light, heart rate monitor is very inacurate, the app is very basic and graphs lack scale. I couldn't get the app to work on my Samsung phone so had to load it up on an iPad. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/26454412-dfyou-waterproof-bluetooth-heart-rate-fitness-smart-watch-black](https://www.desertcart.jp/products/26454412-dfyou-waterproof-bluetooth-heart-rate-fitness-smart-watch-black) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-07*
