Very cool! I didn't know pilots are required to maintain a logbook. What's the official recommendation for this - using a paper logbook?
A lot of people still use paper (and fill it in after landing each flight), but there are quite a few digital options on the market now. I use one called LogTen, which stores everything in a SQLite file behind the scenes which is what I used to make this.
TL;DR: you're screwed.
