I usually do not use my mobile for trading. I feel much better to trade on PC due to big screen and ease of use. Although i do have app for binance on my mobile but i usually use it to see the trades etc, but i normally place the trades when i am on my pc.
It is good to keep bookmark site preev.com to get updated on mobile for the bitcoin prices and other third party apps which will give you notifications on the movement of altcoins.
