Where can I get Soulver 3?

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.

What are the system requirements for Soulver 3?

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.

Do you offer upgrade pricing for existing users?

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.

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.
