Yolt has partnered with Wealthify so people can build investment plans with them, but they have nothing like stock trading. They have more than 500k users and nearly a 5 star rating on the iStore with nearly 9k recommendations. They could be a trusted and valued low-cost funnel.

Both apps help you go from being a spender to a saver, it’d be nice if they can then turn you from a saver into an investor through FreeTrade.
