Best calculator I’ve ever used, and I’ve used a lot of them

I’m an accountant, so a good calculator is absolutely critical. Soulver is so much better than any other calculator I’ve used before. I’m not sure there is anything it can’t calculate, and I only use a fraction of its features. I also really like that it keeps a history of everything I’ve done to refer to later, and screenshot or print for documentation.

Excellent piece of software

Thank you for this.

Excel and Google sheets for Dummies

I have never learned excel and I am terrible at google sheets. After a few minutes of learning the Soulver workflow, I can now easily create Soulver sheets to track expenses or predict cashflow very easily.

I do wish there was a way to export it to google sheets or excel and it would automatically be populated in all the cells, columns, rows so I could easily share with my non-soulver friends.

It would also be nicety have the ability to have short cuts to jump to different parts of the sheet or be able to view it in outline form.

Don’t miss the Soulver 4 upgrade; it’s a homerun

I've used Soulver for years and thought it was already close to a finished product. Version 4 makes that look like a starting point.

The new trip planning workflow alone is worth it — set a start and end date and Soulver maps out your days at each stop and warns you if you overshoot. Beyond that, there's a huge wave of new natural-language calculations (tax, inflation, distance, physics, etc….), smarter calendar math, tags for tracking expenses, custom variables and units, better sheet organization, and a AI-friendly command line for scripting sheets.

And I LOVE that it is a universal app now — one purchase covers Mac, iPad, and iPhone instead of three. For an upgrade this substantial, that's remarkable.

Whoever's building this clearly isn't coasting. Easy recommend, and easily worth the price.

Ver 4 - Great app that gets better and better

I’ve just updated from ver 3 to ver 4. It’s a paid-for upgrade (the first for a very long time). 50% discount for the upgrade. Stupendous value for money. I use this app everyday. The update process (on Mac, iPhone and iPad) is very easy. The app uses natural language and is so well designed it is a joy to use. I have different saved sheets for different tasks (Trig, Electrical calcs, finance, proportions, EV range calcs, percentages, etc) and find Soulver so much more convenient than spreadsheets. Everything syncs instantly between devices.
