Soulver 3 is available on the Mac App Store or from Soulver.app. We offer a 30-day trial, after which you can still view your sheets but editing will be disabled.
If you purchased Soulver 3 directly from us in the past, you can always download it from here.
Soulver 3 requires macOS 10.14.4 or later. This is the first version of macOS that had Swift built into the system.
If you're not running Mojave or later yet, you can still get Soulver 2 (which supports from macOS 10.10 or later) on the Mac App Store.
No, however we think Soulver 3 is still a good deal as is not a subscription purchase. You may also take the following into account when making a decision about whether to purchase Soulver 3:
Soulver 1 (2005) had five years of free updates and worked from 10.4 - 10.14.
Soulver 2 (2010) had ten years of free updates and works from 10.6 to the present macOS release.
Soulver is only available on macOS. However there are numerous Soulver clones available on other platforms:

Yes. Save the sheetbook into a synced folder like Dropbox or iCloud. Detailed instructions on how to set this up are here.
Alternatively, if you just need to sync a single sheet, export it (by dragging it out of the sidebar, or going File > Export > Soulver 3 File), and saving it to a synced location like Dropbox or iCloud Drive.
By default Soulver formats your answers with SI notation:
To disable notation go to the Format menu and untick Notation for Large & Small Numbers .
You can also access formatting settings by clicking the action button on an answer.
To turn off notation for all lines by default, go to
Edit > Tweak Calculator… > Default Formatting
Soulver is powered by SoulverCore, which scans expressions for pre-defined syntaxes and evaluates any valid mathematical expressions it finds. It does not use machine learning algorithms.
If you're curious about how to build something like SoulverCore, read Crafting Interpreters. You could also watch this great talk by Nick Lockwood, and check out his example of a math parser.
