I'm working on a travel planning application. I know a lot of other apps exist, but I'd like to build one myself.

https://github.com/kenrick95/ikuyo

So far it has some sort of activity calendar + expense tracker

There's still so much ideas to implement, like adding map, improve UX of creating activities, to-do list, etc

I've used it once or twice of a short trip, but in 6 months time, I'll have a 2-weeks trip, so that's my self-imposed "deadline" for this project

Anyway this project is a pure static web page and all the 'back-end' is handled by InstantDB ( https://www.instantdb.com/ ) after I saw their submission on HN >.< So far it has been quite a good experience overall except maybe the permissions model which can be a bit confusing to me
