Soulver 3 is available on the Mac App Store or direct from us at 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.
Not this time, no. Upgrade pricing is not supported on the Mac App Store.
We think Soulver 3 is still a great deal. It is a single purchase, and this is the first paid update in about 10 years.
We try to keep both versions as similar as possible but there are some differences:
The direct version has a Share to Mail feature (that isn't possible in the App Store version due to technical limitations)
The App Store version lets you subscribe to additional services, like Soulver Stocks. We only offer services in the App Store version so that subscribers will have access to these services in the upcoming iOS versions of Soulver 3.
No, Apple doesn't give developers a way to do this. If you have an App Store license and would like a direct license instead, shoot us an email.
Soulver is only available on macOS right now. Future platforms are in the works 😉. Stay tuned.
Sure, download your free copy of Soulver 2 from here. This version doesn't require a serial number, and works on macOS 10.10+ and it's native on both Intel and Apple Silicon.
Yes. Move 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 line specific formatting settings by clicking the action button on an answer:
To turn off notation for all lines, go to
Preferences > Calculator > Answer Formatting
and disable Notation for Large and Small Numbers
Use a comment (// this is a comment), or a label (this is a label: ), or put the number in parenthesis (provided another word is present):
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.
The first Soulver (released in 2005) was the first notepad calculator to use an answer column on the right side of the text field, and allow words to be used alongside numbers.
The first notepad calculator we're aware of is MathPad by Mark Widholm, which was originally released for Macintosh in 1993.
Not officially, however there are numerous Soulver clones available on the web and other platforms:
OpalCalc (for Windows) - Thank you for the acknowledgment 💛
​NoteCalc (for the web) - Thank you for the acknowledgment 💛
​CalcNote (for Android) - Thank you for the acknowledgment 💛
Numbr (for the web) - No acknowledgment 😔
Numi (for Mac) - No acknowledgment 😔
Parsify (for Mac, Windows & Linux - Electron) - No acknowledgment 😔
Caligator (for Mac, Windows & Linux - Electron) - No acknowledgment 😔
If you create your own Soulver clone, we'd really appreciate if you would please acknowledge Soulver as the source of the idea.
