As all the technical indicators are working on multiple parameters, I am sure that you need to keep adjusting the parameters of RSI and MACD to keep your signal effective against different market fluctuations which is the reason, no such app is consistent and not becoming famous after years of existing. All exchanges are offering almost all technical indicators for every trading pair hence I guess I may not need to go for any app in my mobile as I do trade on big screens only.
Well I am using this app to track 15 coins and their movent I just need to add bullish and bearish divergence and I don't need any more indicators for myself. But in general, this app also can be used for testing some strategies. I will maybe in the future add statistics for alerts so I can see what is the best indicators combination(but don't have time much now so this will wait after the new year
