How to choose the best investment app

When it comes to choosing which investment app you want to use, you should consider what it is you’re looking for. Are you looking for something to set up and leave alone, such as Moneybox? Or do you want something that’s a bit more personal and talks you through everything, like Plum?

Consider the following:

  • Fees. Work out how much it will cost you to invest the amount you want to – would it be cheaper with another provider?
  • Products available. If you want to invest in a stocks and shares ISA, check that the providers have this available.
  • Portfolios. Do you want to have a lot of choices when it comes to choosing portfolios?
  • Ethical investing. If you’re looking for ethical investing, check out the providers that offer this and what their ethical portfolios are invested in.
  • Tools. If you’re just starting out with investing, consider choosing a platform that has more guides and video walkthroughs to help you out.
