# About Glowbug

Glowbug is a small studio making native Mac apps that each do one job well, with no subscriptions, no accounts and nothing sent off your Mac.

Glowbug is run by **Ayesha Gagan**, an independent developer who builds apps for macOS. Each app starts with one everyday annoyance: files piling up on the Desktop, a MacBook that sits at 100% all day, invoices that take longer than the work.

## How the apps are made

-   **Native.** Written in Swift and SwiftUI, made only for macOS, so they look and behave like part of your Mac.
-   **Private.** They do their work on your Mac. No accounts, no analytics in the apps, and your files, battery data and invoices stay with you.
-   **Pay once.** No subscriptions. A license works on up to 3 of your Macs, with free updates.
-   **Tested for real.** Every release runs its self-tests on a real Mac first: Shelfy drives the real mouse, Chargeberry switches real charging on a MacBook and checks it always comes back, and Invoicewell runs 602 in-app checks.
-   **Real support.** Email [adgan.business@gmail.com](mailto:adgan.business@gmail.com) and the person who wrote the app answers.

## The apps

[**Shelfy**](/shelfy): A file shelf beside your Dock. $9.99, first released 18 October 2026.

[**Chargeberry**](/chargeberry): A kinder way to charge your MacBook. $5.99, first released 25 October 2026.

[**Invoicewell**](/invoicewell): Invoices you can just ask for. $19.99, first released 1 November 2026.

## Why “Glowbug”

A glowbug is a firefly: small, quiet, and lit from the inside. That is the idea for every app here. They sit in a corner of your Mac, use almost nothing, and do one thing that makes the day a bit brighter.

> According to Glowbug’s own measurements, Shelfy and Chargeberry each use about 0.1% CPU while they wait in the background.
> 
> Measured on a MacBook Air (M1, 2020), November 2026. Details on each app’s page.
