I thought I'm done with Unplug Alarm Client for Android... but that didn't turn out well... 🙄 So that's what I've been up to the last few days. Unplug Alarm's Android client app. More details about this in my weekly newsletter. (Subscription link in bio — it's free 💁🏻‍♂️). I took some time off and now I'm BACK from my hiatus fired up for work and pretty much exuberant to bring new stuff down to the table 😎. Sort of a multitasking day for me.🧐 This is how my notebooks looked like prior @Mockup.App 😅 Sundays are usually the pause button. But not for me!!
