Mac and Windows

Same release. Same day. Both platforms.

Redpen is a desktop PDF app that runs on Mac and Windows. Every version is built for both from the same code, so the Mac users on your team get the same tools, at the same time.

What you get on a Mac is what you get on a PC.

One codebase, one release, one price. The estimator on a MacBook and the PM on a Windows laptop work the same set with the same tools. The plan each part sits in is the same on both.

M-02Desktop

Installed on your machine, and it works like it.

Redpen is a real desktop app on both platforms, not a browser tab.

Works offline

No connection needed to work. A paid plan checks in at least every 14 days, so the trailer, the basement and the plane are all fine.

Files stay on your computer

Sets open from your own drive and save back there. Nothing is uploaded.

Updates when you're ready

A new version waits and installs when you say, not halfway through a takeoff.

Keyboard first

Standard shortcuts on both platforms, a / command bar, and every key editable.

M-03Questions

Mac and Windows, answered.

Is the Mac version the full app?
Yes. Mac and Windows are built from the same code in the same release, with the same tools. There is no lighter Mac edition.
Which Mac build do I need?
Apple silicon (M1 and later) or Intel. To check, open the Apple menu, then About This Mac: a chip named Apple M and a number means Apple silicon.
When a new version comes out, does the Mac get it later?
No. Each release is built for Windows and Mac in the same run and published under the same version number, the same day.
Does it run on Apple silicon?
Yes. There are separate builds for Apple silicon and Intel Macs, so neither runs under emulation. macOS 12 or later.
Is the price the same on Mac?
Yes. Pro is $199 a year or $24 a month on either platform, and the free app costs nothing on either.
Can a Mac and a Windows PC open the same file?
Yes. Redpen saves standard PDFs, so a set marked up on one platform opens on the other with its markups and measurements.
