Free tricount like application. If you want to use/try it, go to https://faircount.web.app. PWA can be installed to your smartphone.
I won't pay for hosting it, so it can be broken due to Firebase free quota exceeded.
I assume it can be deployed to any firebase project if you want to keep it private.
We were using tricount with my family but we had to pay for it. I wanted to try building a PWA using angular and firebase with its firestore DB. So here it is ! ;)
You can help building a better app by proposing PRs or you can ask for new features using issues.
Have fun, cheers
