Plug-That-In [https://plugthat.in] (Mac App; Paid)

An annoying little laptop charging reminder utility that does the job.

---

There are times when I'm deeply immersed in focused work, a meeting, or engaging video content and end up missing the usual low-battery notifications on my MacBook.

When the laptop suddenly shuts down, it's followed by the familiar and frustrating walk to find a charger or power outlet. It can be annoying and occasionally embarrassing, especially when rejoining a session a few minutes later with, "Sorry, my battery died."

Over the past few weekends, I built Plug-That-In, an app that introduces "floating/moving notifications". These alerts follow the cursor, providing a stronger, harder-to-miss nudge regardless of what’s happening on screen.

The app also includes a few critical features:

- Reminder Mode: When the battery reaches critical levels, the app emits a configurable alert similar to a car's seatbelt warning, continuing until the battery is addressed.

- Do Not Disturb Settings: Customize alerts and sounds based on context, such as when system audio is playing, a video is active, or the camera is in use.

It grew out of a personal need, and I'm glad to see it used by over 50 people in the past month.
