Soulver

2.7.1

Smart notepad with built-in calculator.

**Soulver** helps you do quick calculations and work things out. It's quicker to use than a spreadsheet, and smarter and clearer than a traditional calculator. You type out your problems as you would on paper, and Soulver calculates your answer as you type. You can do calculations over multiple lines, and use words alongside your numbers so they make sense. Soulver is great for adding things up, easily doing percentages, and converting things, like currencies.

Use Soulver to play around with numbers, do "back of the envelope" quick calculations, and solve day-to-day problems.

- See all your calculations all the time, and go back and change any of them
- Use words amid your calculations so your numbers make sense
- Easily do percentages ("$100 - 10%", "30 as a % of 200")
- See a running total of all your lines
- Do easy conversions ("10 USD in Euros, "25 meters in feet")
- Do calculations with stocks ("100 AAPL")
- Connect your lines together using answer tokens
- Create variables to hold frequently used numbers
- All the standard mathematical functions
- Support for calculations in binary and hex
- Save and export your work.

Version 2.7.1:

- Soulver 2 is now notarized (required for 10.15 Catalina)
- Fixes a rare crashing bug

Version: 2.6.7

This is where the Apple App Store really irks me. I have the App Store version of Soulver and its crashing on launch. The App has been updated to version 2.6.7 but not on the App Store. I’m left with a crashing app because I can't update my version. This has become beyond tedious.

Version: 2.6.4

Been using this a 2-3 times a month for two years. Replaces simple spreadsheet calculations, and it is a joy to use. Bulletproof. The UI is a little threadbare but it is still perfectly usable.
I would miss this app if it were gone.

Version: 2.6.2

After testing out a few text calculators, I find the Soulver the easiest to use with the best interface at the moment. It provide complex functions for advanced user but it's easy for beginners to utilize it’s basic functions to save a lot of time.
The ledge format calculation allows bulk entry to perform calculations which saves a lot of time compared to entering each number one at a time on a traditional calculator.
I would have gave it a higher score if the interface had a more up-to-date modern interface design.

Version: 2.6.0

Simple interface without bright trendy colors, but the app manages the calculations perfectly. I use it very often when need to do count some thing. Great feature is managing with currencies. I think, Soulver is better than a traditional calculator, indeed. It's more functional. I suppose, it's a one of a basic tools for macs.

Would really like it if we could change the background color so we can have a "dark" calculator. Right now it seems as though this is an oversight. Am I missing some obscure option @developer?

Version: 2.3.3

It's on my iPhone, iPad and Mac. It's my default calc app. Good work guys.

Version: 2.3.1

I love this thing. Use it a lot, so much better than teh plain old boring Apple calculator.

Version: 2.3.0

Thanks for adding iCloud sync. I typically only like using Dropbox sync when its a document that would ideally reside in a folder. Soulver is more of a unique take on a calculator and most people don't necessarily think of a calculator creating and managing documents. Awaiting the refreshed iPhone and iPad apps.

Version: 2.2.2

I was a big fan of this app for a long time. Now I think Numi (http://www.macupdate.com/app/mac/41550/numi) is full enough for all my calculations. It five times cheaper and always available over hotkey.
Anyway, good app.

Version: 2.2.2

Clever idea. I didn't saw this combination before.
BTW any luck lowering the asking fee? It is just to expensive.

Version: 2.1.4

Any chance you guys at soulver could take this source and implement it all in your app?

Now that would be cool the power of a ti-89 in a simple quick mac app like this I would pay ten fold for.

Soulver - an innovative new type of calculator that allows you to perform calculations using simple English. However, it also contains a number of other interesting features.
For example:
1. Soulver not lost the skills of their prime "brothers":
Expressions are considered as they are entered rather than at the end.
2. Soulver - allows you to write expressions in plain English:
3. Soulver - supports multi-line calculations with the possibility of by-line editing (the result is automatically recalculated). Starting next row from the sign of action, you give the program to know that all actions in this line - the continuation of the previous one.
4. Panel "answers" and "Statistics" display additional information about the selected row and computing in general, respectively.
5. Soulver - working with variables and constants:
The application also allows you to add your own constants and functions to the library for further use, which greatly simplifies the adjustment of the application for themselves.
6. Soulver - supports all necessary functions from the sinus to the logarithm, and calculates up to 100 digits after the decimal point.
7. Soulver - can save their work and treat them as textual information: change color, font,
Personally, I particularly liked the immediate response to an application to change any values in the expression. In this case, an automatic recount result in any mode of computing.
As a result, we have a very functional and easy to use application with a number of interesting features.
Therefore, I can say only one thing - Soulver essential tool for your Mac.
I express my gratitude to the developers!
Sincerely Vitaly!

Version: 2.1.2

This gets 5 stars for the price and innovation.
It is like a really good basic scientific calculator with a tape running so you can record your session. I think the idea comes from texas graphic calculators et al who already do this but costs a lot more than 25 bucks (of course still they can do a lot more than soulver currently).
ASCII sucks to do math with and to buy software which handles equations costs a lot more money. This does not handle most algebra out with the basics. If this is your only need I would look elsewhere. But at $25 it is not meant to do all that anyway. It does really well all the same with powers and functions.
Request to developer allow me to make the white background black (with transparency option) please. The highlighting is great but this is missing.
I prefer this to a calculator on OSX for all those little calculations. It starts out you hate it but then love it. It is one of those you need to keep using to get into.
Speed wise it is very fast much faster than messing with clicking icon buttons. You can also grab the expressions and put them in your notes quickly as it is just ascii.
If maths is your thing have a play.....

Soulver has found a permanent place in my dock and I haven't quit the application since I purchased it. I grew up using multi-line calculators and loved being able to see and verify my work without having to rekey everything. The multi-line window was my main motivator for checking out the program but I'm finding more uses for it every day. Lately I've been planning vacation expenses across a few countries with different currencies and I am able to see line by line how much everything is costing in US dollars. Exchange rates are automatically imported and updated.

The calculator done right. Very nice app.
Hm why not using International preferences for decimals and thousands ?

Feb 14 2007

Version: 1.4.3

This might make an interesting widget, memory permitting.

Nov 7 2006

Version: 1.4.2

Revised review: Satisfactory. Looks nice, works well for what it's intended for (complex numbers are clearly not what it's intended for), clean and spiffy. I doubt I'm part of the intended audience but for what it is, it's a fine program.

Jun 17 2006

Version: 1.3.3

For my purposes (a calculator more advanced than the included one), Soulver is really great. It's fast, clean, and is about 5x more useful / nicer than Calculator app's built-in "Paper Tape" feature. Sure, it's no Mathematica, but I also didn't drop a few grand on this, so I've been nothing but satisfied, and no regrets on the $13 I spent.

Jun 15 2006

Version: 1.3.3

Unsatisfactory. Doesn't even recognize complex numbers, and not only crashed but brought my system to a grinding halt when I tried to enter:
y = 2x + 5
x = y + 2

I downloaded Soulver to see whether it would be useful for my kids to do their Maths homework. For primary/mid school students, I can say this is a *fantastic* application. It looks excellent for upper school, but haven't seen it used there.
Soulver has a very simple interface - if you just open it and type (e.g. 2+2) you see the answer immediately - very intuitive.
The big advantage Soulver has is that it lets the student show each stage of solving a problem. Homework assignments are done completely in Soulver - type a heading/date/name, type question numbers, and then type expressions/equations and results.
Soulver lets you combine lines of text and numbers, while easily resolve the value of expressions. So an algebra problem might go:
Q2. Solve 4a -2b where a=4 and b = 3
4a - 2b
=(4x4)-(2x3) (Soulver shows answer as 10)
=10
For younger maths students doing homework, this is invaluable.
Soulver lets you easily enter mathematical symbols (divide, square root) as part of equations.
I compared Soulver to MathPad. For some inexplicable reason, MathPad seems to think that showing the working out for long division and long multiplication is vitally important. News for MathPad - it isn't. Mathematics teachers have moved on, and nowadays its perfectly acceptable to calculate 625/25 with a calculator, rather than having to work it out the long way. The US assocation of mathematics teachers is very clear on this, as are other mathematics bodies.
The Soulver approach is to provide a clean worksheet enviroment for kids to work in. They can do all their homework assignment and then print-PDF-mail it to their teacher or print it out and hand it in.
If you have kids at school, download the software and try it. It all just works.

Version: 1.2.1

I wasn't going to post a review because as a long time MathPad user I figured I would be biased against this. The developers originally described this as a "mathpad with style" so I figured I'd check it out. Since they are asking a shareware fee and MathPad is free it seems fair to compare.
MathPad is a very powerful general purpose program but I'll just compare its use as a simple calculator since that seems to be Soulver's intent.
Soulver uses a slightly different interface concept than MathPad. It evaluates each line of text as it is typed and puts the answer (if any) in a separate column to the right. This is easier for first time users. In MathPad you have to learn to hit the enter key to see your answers. Once you learn to hit enter, the net effect is about the same.
MathPad evaluates the entire worksheet rather than individual lines. This allows more complex calculations to be built up from multiple equations over multiple lines.
Soulver provides a total of all the numbers in the answer column. This is a handy feature if the numbers are related and the total is meaningful.
Soulver claims to have built-in equation solving. This is something MathPad does not have built in. However when I tried Soulver, even simple equations took minutes to never to solve (900MHz G3). Editing the equation and getting it to solve again didn't seem to work at all.
MathPad's interface is a bit old and clunky. Soulver tends to look nicer but this version still has some bugs. I had occasional trouble with cut and paste. Also when editing text, the answer column sometimes duplicates numbers on lines that don't have answers.
Soulver attempts to be a bit more elegant with input notation but its superscript entry is cumbersome to unworkable. Entering something like 4^(1/2) doesn't work.

Nov 13 2005

Version: 1.2.1

It isn't really a NEW "kind of scientific calculator which features a word processor style interface with instant calculation" since MathPad has been doing that for years. It may have more (or at least different) "style" than MathPad.

May 23 2005

Version: 1.0

Found this cool app on the MacUpdate home page this evening.
It has a really cool concept. I love the equation solver part. I'm really liking the 'dashboard' like answers pallette. It shows decimals and notation in real time.
It will be good to see how this progresses. Pretty solid for a 1.0 release.
