The two ReliCheck apps for research on the Mac are now on the Mac App Store. As of today, Quanta and Quala can be installed the same way a researcher installs anything else on the machine. One click, one authentication, one app in the Applications folder, and updates handled by the same system the user already trusts for every other tool on the desktop.
That is a small sentence for a category that has spent twenty years working around it.
The old distribution story
Statistical software on the Mac has for a long time been delivered on the outside of the platform's normal distribution flow. A researcher would download a disk image from a vendor's website, drag an application into the Applications folder, sometimes install a Java runtime, sometimes install XQuartz, sometimes install a license manager, sometimes work around a Gatekeeper warning that had to be dismissed with a right-click. IT departments approved these installs one at a time, or refused to, or blocked the updates the vendor was quietly pushing. None of that was hostile. It was just how software of that era arrived on the Mac.
The Mac App Store rewrites that flow. Installs come with Apple's own notarization. Updates arrive through the same mechanism the user already uses for every other app. Sandboxing is enforced by the operating system. A researcher who wants to know exactly which version they ran on a study can point at the store and check.
What Quanta and Quala do
Quanta is a native macOS application for quantitative analysis, built in Swift for Apple Silicon. Coding items, reliability checks, item-total correlations, factor analysis, and the reports that come from all of that live in a workspace that opens fast and moves at the speed of a real desktop application.
Quala is a native macOS application for qualitative research. Transcripts, codes, memos, themes, intercoder agreement, and the write-up that draws on all of that live in a workspace built for the researcher who codes at eleven at night, three hundred excerpts in, on the same machine that has to hold up all day.
Both apps started from the same idea. Build for the machine the researcher is actually going to open. Do not translate a Windows tool. Do not wrap a web app in an Electron shell. Write it in Swift, on macOS, from the first line of code.
Two apps, one idea. Research software that belongs on a Mac because it was built for one.
What changes for the researcher today
The friction that has kept some researchers on Windows for the stats part of the day is not the analysis. It is the install, the license manager, the update dance, the IT ticket. Bringing Quanta and Quala into the Mac App Store removes most of that layer. A researcher who has already logged into the machine has already handled the trust question. The install is one action. The update is silent.
Reproducibility gets easier too. A study that reports "Quanta 1.0.2" from the Mac App Store is a study that a reviewer, a coauthor, or a future version of the researcher can retrieve exactly. That takes a small piece of ongoing anxiety off the table, about whether the software the analysis ran on will still be available five years from now.
For labs and departments
An institution that wants a consistent research stack on a fleet of Macs can now handle it through the same Volume Purchase Program and MDM tooling already used for every other Mac app in the department. The stats and the qualitative side are no longer the exception on the license spreadsheet. They are two more apps on the standard image.
What comes next
The apps launching in the Mac App Store today are the start of a wider effort. MM Studio, the mixed-methods bridge between the two, is next. Signal, the writing you are reading now, will continue documenting the choices, the tradeoffs, and the working conditions researchers are actually operating under in 2026.
Today the story is short. Two ReliCheck apps for research on the Mac are on the Mac App Store, native to Apple Silicon, notarized by Apple, and installable in one click. For a category that has been off to the side of the Mac for a long time, that is not a small change.
