| Items tracked | In development | Yearly Cost |
|---|---|---|
| ~10k | ~1 year on and off | ~$13 |
Ooradee is a TODO app that I built to replicate the system I had on paper. It's key feature is different time horizons allowing me to schedule todos on specific dates but also for weeks and months in general. It also has a specialized interface for review helping me track progress on things I'm working on.
It's a PWA on Rails 6 with webpacker and Vue. It's installable on desktop and mobile. It can send notifications to Chrome. It runs ActionCable for background updates.
In progress. It's my testbed for new tech and I've learnt a lot about design from it.
