It will be very useful if there is an app for opentrade, coin, sentinel and tradingqna also.
Opentrade will no longer be active. An app for Coin should be available soon and building one for Sentinel is on our list of things to do.
You can add a PWA of Tradingqna to your homescreen. If you are using an android device open Tradingqna on Chrome mobile, open the settings menu and click on “Add to homescreen”.
