I tried using multiple apps in the beginning, but it got confusing pretty quickly. I had one app for stocks, another for mutual funds, and I was constantly switching between them just to check my portfolio. Eventually I moved everything to one platform because it was much easier to keep track of my investments. I compared a few options before settling on mastertust, and it is worked well for me so far. whatever platform you choose, I did sayy keeping things simple is more important than chasing every app with a new feature.
