Purchasing Questions
Where can I get Soulver 3 for Mac?
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 is disabled). 
If you have purchased Soulver 3 directly from us in the past, you can re-download it from here.
Do you offer upgrade pricing for Soulver 2 users?
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. 
Is there a difference between the direct and App Store versions of Soulver?
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 has an additional (optional) subscription service: Soulver Stocks​
Can I transfer my direct license into an App Store license?
No, Apple doesn't give developers a way to do this.
What are the system requirements for Soulver 3?
Soulver 3 requires macOS 10.15 (Catalina) or later and works great on the latest macOS.
If you're still on macOS 10.14 (Mojave), you can download an older version of Soulver 3 which still supports this version of macOS.
Is Soulver available for iOS?
Soulver is only available on macOS right now. An iPad version with feature parity with the Mac version is in development. 
I purchased Soulver 2 in the past, can I download it again?
Sure, download a free copy of Soulver 2 from here. This version doesn't require a serial number, and works on macOS 10.10+. It is native on both Intel and Apple Silicon.
Technical Questions
Can you sync sheetbooks between Macs using iCloud?
Yes.  In Soulver's General Settings, select "iCloud" under "Sheetbook Location.
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 save it to a synced location, like Dropbox or iCloud Drive.
How do I turn off notation in answers?
By default Soulver formats your answers with SI notation:
M stands for million
To disable notation go to the Format menu and untick Notation for Large Numbers .
The answer with notation disabled.
You can also access line specific formatting settings by clicking the action button on an answer:
Contextual Menu on an Answer
To turn off notation for all lines, go to 
Settings > Calculator > Answer Formatting
and disable Notation for Large Numbers
How can I get Soulver to ignore certain 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 telling me 1 GB is 1000 MB. But 1 GB is actually 1024 MB, isn't it?
Soulver conforms to the industry standard binary prefix system, which you can read about here:
Binary prefix
Wikipedia
The gist of it is that special units have been introduced to represent base-2 binary units (KiB, MiB, GiB), so that units like k, MB & GB are able to behave like normal base-10 units.
Why isn't Soulver remembering my window positions?
Soulver supports "Resume", a feature in macOS which restores the position of your windows on launch. For Resume to work correctly, it's important you don't close your windows when you quit Soulver.
Ensure that the "Close windows when quitting an app" setting is disabled in the macOS General System Preferences:
Make sure you're not closing Soulver's windows when you quit the app!
Does Soulver use machine learning/AI?
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.
Was Soulver the first notepad calculator?
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.
Is Soulver available for Windows & Android?
Not officially, however there are numerous Soulver clones available for the web and other platforms:
​OpalCalc (for Windows)  - Thank you for the acknowledgment 💛
​NoteCalc (for the web) - Thank you for the acknowledgment 💛
​Parsify (for Mac, Windows & Linux - Electron) - Thank you for the acknowledgment 💛
​CalcNote (for Android) - Thank you for the acknowledgment 💛
​Numbr (for the web) - Thank you for the acknowledgment 💛

We welcome Soulver clones on other platforms. Great UI concepts are meant to be copied, and innovated upon. 
We would only ask for an acknowledgment and a link back to Soulver.
