Playdate (PD) Dev Series 2: About JustOne
Hey everyone, this is a new series of posts about my time with Playdate development. This as more of my thoughts and notes rather than a full-blown devlog on how I did/am doing things, but I still hope people might find this useful.
I will try to intentionally keep the posts short and straight to the point. Find the previous post in the series here
JustOne

As mentioned in the previous post, my first project is a desk companion app called JustOne. The app aims to help you focus on the most important thing each day and it's an "excuse" for me to learn the concepts of Playdate development.
I am not aiming for this to be another task or reminder app, but rather a more mindful way of remembering what matters. It can be a task or a reminder, but also anything important to you like an inspirational quote, a date, or an excerpt from a poem.
I am working on it on the side for a little over a month and I am making some good progress so I think now is the time to discuss more about it's features and show some progress.
Features
The current work-in-progress version has the following features:
- Ability to enter the current task with data persistence - task resets at midnight.
- See current date, day progress as a percentage and progress bar at a glance.
- 7 Backgrounds to choose from using the Crank.
- Hide UI option in the system menu (this hides all text and bars except from the current task and the background).
- Dark Mode option in the system menu.
- Playdate auto-lock is disabled when the app is active - for keeping your playdate on your desk with the app running.
Working on:
- Logic to automatically cycle through the backgrounds at specific intervals e.g. 5 mins, 15, 30 and 60 mins.
- Some fun PD achievements.
Considering for the future:
- Some basic stats
- More backgrounds
