I'm very curious, what is it about Binance's app that you don't like? I don't like the fact that they log you out, if you don't use the app for a period of time, but aside from that, I think it does the job just fine, at least for the average users.
I use it frequently, they still log me out. Binance future trading is not that good for me like how it is on some exchanges, the exchange still using the old style that consumes more data like 50 kb/s every seconds on 1080 pixel resolution phone, unlike two exchanges that are consuming 2 to 10 kb/s.
Exchanges need to move to unified trading account but I do not think Binance will do it.
If you open many tabs and you leave the Binance, if you go to the Binance back after some minutes, it can take up to 5 seconds before you will see the accurate charts and your PnL, but which is faster on some exchanges.
I think their security feature is that you log out after closing the app, and that's not a big deal for me.
I haven't tried any exchange app other than Binance, mainly because I really like the p2p trading it offers.
Is your internet connection limited, or are you worried about consuming data?
That's not a concern for me since I'm using a Wi-Fi connection.
IMO, the best exchange app is Binance, which is why I haven't looked at any other app.
If you're trading, the app isn't reliable, it’s better to use the website on your PC to monitor the real-time chart.
