is now free to everybody. The service lets you create a custom portfolio (Pie) of stocks and ETFs, custom weight each investment (slice), so that when you add new money it will invest it to bring the slices in balance with the chosen allocations.
The platform uses fractional shares so that you can, for example, invest $100 a month in 100 stocks trading at above $100 a share. It won't ever sell anything unless you ask to withdraw money or change a weighting to 0%, OR unless you choose to manually rebalance the pie.
This is a fantastic deal. The app, is very slick as well. I really like being able to auto-invest into a portfolio of my choosing (though you can invest in their off the shelf portfolios as well.
