Basket Investing App for Stocks/Crypto?

Problem

I have multiple investing apps between crypto and stocks - Robinhood, Fidelity, Coinbase, Binance, ThinkOrSwim, Stash, Acorns, etc... I've used them all for one reason or another, but they're all missing one key feature:

I CAN'T SET UP RECURRING DEPOSITS THAT GET EVENLY DISTRIBUTED ACROSS MY PORTFOLIO!

Example: I own 4 Stocks and an S&P 500 ETF. Every payday I want to add $100 to my account, evenly. Sounds easy right? Nope. On most apps you need a recurring investment set up for each stock. Or it goes straight to cash and you have to move it later. Hard to setup. Harder to maintain.

Solution

I've started to build an app using the Alpaca trading platform (https://alpaca.markets/broker) that will allow you to:

1. Pick your stocks/assets (hopefully including crypto)
2. Pick your target allocation %
3. Set your recurring deposit amount/frequency
4. Literally profit

Right now its just a MERN stack app on Heroku and a landing page I made with KickoffLabs at www.fundkit.io (Needs a ton of work right now, but I needed to just start on SOMETHING).

Anyway, curious what folks think about my problem/idea. I've been a long time consumer of IH content but first time posting. Hopefully this marks the start of something cool. Appreciate any comment, thoughts, questions, or criticism!
