Tools I build

Stackyard

Windows and Mac · v1.0.3 · free

Every SDK on your machine, which projects use it, and what's safe to remove.

Version managers install SDKs; nothing tells you that you have six Flutter versions, three Android NDKs and a 13 GB emulator you haven't opened in a year. Stackyard scans your machine and your projects, shows what each version is used by, explains every problem in plain words with a button that fixes it, and frees the space you don't need. Free and open source.

Notchet

Mac · v1.0.11 · 7-day trial, then $2.99

Everything you copy, one notch away.

A clipboard manager that lives in the MacBook notch. Notchet keeps everything you copy, text, images, links, colours and files, and drops out of the notch when you press Option Command V or rest the pointer there. Pick a card and it pastes right where you were.

Launch price until Oct 26, 11:59 pm Pacific Time, then $4.99

DisplayShift

Mac · v1.7.8 · 7-day trial, then $2.99

Plug in a monitor and choose which windows move over.

A menu bar app for anyone who docks a MacBook. When a display connects, a panel drops out of the notch with every open window listed, full screen apps and other desktops included. Tick what should move and it glides across. It remembers your layouts, puts windows back after sleep, and tiles up to four apps side by side.

Scrollwise

Mac · v1.2.3 · free

Natural on the trackpad and Apple's Magic Mouse, classic on a wheel mouse. Automatically.

macOS has one scroll direction switch for every device, so anyone who uses both a trackpad and a mouse flips it back and forth all day. Scrollwise checks which device each scroll comes from and fixes the direction on the fly. Apple's Magic Mouse is recognised on its own and scrolls like the trackpad it really is. Leave the macOS switch alone and never touch it again.
