Shamelessly plugging You Need A Budget. Best app I've ever used. My SO and I have been using it for about 3 years now, and the app has been instrumental in us becoming mostly debt-free.
YNAB is a glorified spreadsheet and did not import past data. I found it exceedingly tedious and not helpful. I am currently using Monarch and it's far, far better. It's a bit pricey, but so far as I've found, it's the best.
They give you a link that allows others to try monarch for 30 days (rather than their egregiously short trial of like 7 days):
Buckets is a free alternative that I switched to when ynab massively increased the price and dropped their grandfathering agreement. Same principals as ynab, but suited me a lot better and is much much cheaper.
