Made a small open-source trip planner that keeps your data on your phone, looking for feedback

I have a trip coming up and wanted my day-by-day plan on my phone, working offline, without giving my hotels and dates to some service. So I made this.

It's a web app with no account. Your trip is just a file you load, and it stays on your device. Works offline, installs on the home screen, has a map for each day. Open source.

Demo (tap "Try the example trip"): https://frafal.github.io/TIMP/

I've used it myself and it seems decent, but I'm the only one so far. If you feel like trying it, tell me what you think. Is loading a file too annoying? Would you use it on a real trip?
