I just discovered the news about TripCase, I've got trips dating back to 2011 on there, I'm glad I found out and was able to export trip data before it was too late.
At about 2019 or so I switched to using Kayak's app for trip tracking because at the time they tended to do a better job of parsing the flight, hotel, and car rental emails I sent to them, so I don't have to do much in the way of manual entry. It's not perfect, so I think I'll be giving Tripsy a try, but if you're looking for a new app Kayak's trip tracking app might meet your needs.
