Apps for the Mac and iPhone, made by one person.

I make Crosswire for running Windows software on a Mac. Goalkeeper is an iPhone app I'm still building for soccer scores and goal alerts. Neither one tracks you.

Crosswire

I forked Whisky after it was archived in April 2025 and kept working on it as Crosswire. It runs Windows games and apps on Apple Silicon Macs. Windows support ships in the app.

Crosswire

Drop a Windows .exe onto Crosswire to install it. Installed apps live in your library, and you launch them from there.

Each app installs in its own space. During install, Crosswire checks for common Windows runtimes and can offer to add them. I publish Crosswire's source under GPL-3.0.

Goalkeeper

Follow clubs, leagues or national teams and set alerts for each one. The Matches tab lists yesterday's, today's and tomorrow's games, with men's and women's competitions in one list. Alerts don't send yet. Goalkeeper will be free to use, with light ads planned and a paid tier to remove them.

Coming to iPhone.

Updates

Sep 21 Crosswire
v1.1.15: steadier first-run setup. Reopening the setup window while an install was still running could make Crosswire download Windows support a second time. That no longer happens, and the progress display keeps updating throughout.
Aug 26 Crosswire
v1.1.14: no download on first launch. Windows support now ships inside the app. First launch is faster and works without downloading anything.
Aug 22 Crosswire
v1.1.13: a new look for app pages. The app detail view has been redesigned around a dark hero layout.
Aug 20 Crosswire
v1.1.12: redesigned launcher. The launcher has a new look, and leaving the beta channel now works reliably.
Jul 22 Crosswire
v1.1.11: a better-looking library. App icons now render as title banners in your library. Icons that previously failed to load display correctly, and a slow first-time setup is given more time to finish.
Jun 9 Crosswire
v1.1.10: clearer setup. Reworded the setup steps and tidied up the loading state.
Jun 8 Crosswire
v1.1.9: smoother installs. A freshly-installed app now opens reliably on first run, and the extra runtimes some apps need are detected automatically and added with one click. No Terminal, no manual steps.
Jun 6 Crosswire
v1.1.7: optional crash reports. Crosswire can send anonymous crash reports to help fix problems faster. It’s off by default and asks once on first launch, entirely your call.
Jun 5 Crosswire
v1.1.6: updates working again. Auto-update and first-run setup were pointing at a retired download address. v1.1.6 moves them to the current one, so Check for Updates and fresh installs work end-to-end.
Jun 2 Crosswire
v1.1.5: light & dark, done right. Crosswire now follows your Mac's Light or Dark appearance automatically.
Jun 2 Crosswire
v1.1.4: the icon is back. v1.1.3 shipped without its app icon and the refreshed interface, built against the wrong system SDK. v1.1.4 rebuilds on the current SDK so the icon and new look render correctly, with a guard rail so it can’t regress.
May 26 Crosswire
v1.1.2 shipped. Built-in Windows programs (Internet Explorer, Windows Media Player) no longer clutter the app list. Install failures now show an alert with the log path instead of leaving you with nothing installed.
May 26 Crosswire
v1.1.1: auto-updates fixed. Sparkle was using Whisky's signing key, so update delivery was broken. Fresh key is in, Check for Updates works end-to-end. v1.1.1 is a one-time manual download; from here, updates arrive automatically.
May 26 Crosswire
v1.1.0: apps appear by name. Crosswire now reads the Start Menu shortcuts an installer creates and shows the real app name. Notepad++ shows as Notepad++, not "npp.8.9.6.Installer.x64". Settings moved to a minimal view: icon, name, Run. Advanced controls are one tap away.
May 21 Crosswire
Crosswire is here. New identity, new bundle ID. The fork that kept going now has its own name.

About

Casita Software is my one-person studio. I build Crosswire and Goalkeeper.

I moved Crosswire onto Gcenx's maintained Wine builds. The code is on GitHub under GPL-3.0.

A casita is a little house. In Puerto Rico, and in the Puerto Rican neighborhoods of New York and Chicago, casitas are where people get together. That's where the name comes from.
