A while back I was using Simple as my bank because their app was the best budgeting tool I'd been able to find. Once it shut down I moved to a spreadsheet, and by comparison it was super painful. I basically replicated the app's functionality as a webapp, with a few tweaks to better fit how I was using it. Currently I'm still entering transactions manually, but I'm slowly building a Plaid integration to automatically import transactions. I'd probably have it done by now, but my current bank made some changes that prevent me from connecting it to Plaid so I'll have to change banks again before the integration will be able to pull in 100% of my transactions. I can't say it'll never be publicly available, but I don't have any current plans to release it.
