Software Made Simple

Software Made Simple has been my slogan for as long as I've been developing software. Many years ago I did a presentation about this as a "lightning talk" in a conference keynote. Here's an updated version.

Simple Sells

Simplicity is a popular topic these days. But other than being cool, what are some reasons you should put more effort into simplifying your software? Because simple sells. Here are some examples:


Perhaps the best known case of taking something that was complex and providing a simple alternative is the iPhone. Back in 2007 before the iPhone came out, nearly everyone had a cell phone and nearly everyone hated their cell phone. Apple took a step back and created a phone that anyone could use. In fact, when the iPhone was first released we stopped at an AT&T store to check it out. My daughter, who was 5 years old at the time, was able to pick up the iPhone take pictures, play music and make a call without us showing her how. She certainly couldn’t do that on my Samsung cell phone.

Sure, Apple took a bit of flak for the iPhone not having all the features that some expected for a smart phone. But it had enough and the lack of features certainly didn’t hurt sales. Now Apple is the largest company on the planet and has just recently passed $1 trillion in market cap, largely based on the iPhone, so it seems like their vision worked out OK for them.


I love Sudoku. It’s really simple to learn. You can explain the rules in less than a minute. It became a phenomenon precisely because of this.

Digital Photos

I’ve convinced more people to get a Mac by showing them the Photos app (and iPhotos before that) than any other reason. People love taking pictures and Photos makes it simple to manage your pictures. It eliminates any fear of editing your pictures because you can always go back to the original with just a single click.

Cloud File Sharing and Backup

First it was Dropbox, which made it stupidly simple to share files across your devices. Plus it also worked as a sort of backup for many people without a lot of files. And it was free to use (for a small amount of storage). Others jumped on the bandwagon and now you also have OneDrive and even iCloud Drive. BackBlaze and other cloud backup services took off from here and provide unlimited backup storage for your files, all handled automatically without you having to do anything.

Wii and Switch

I particularly like this example. Nintendo took what many thought was quite a risk by releasing the Wii in 2006: a game system that was much less powerful than either the XBox360 or the Playstation 3. In the end, Nintendo was proven right. They reasoned that most people wanted to have a game system that was fun and approachable more than one that was incredibly realistic and complex. They messed up this philosophy with the Wii U by making things more complex but got it right again when they introduced the Switch.

Simple is Easy

For your users, simple means one thing: make it easy to use. This can mean a lot of things to different people but the key thing to keep in mind is that your software should be approachable.

Your users don’t want to read manuals or go to training in order to effectively use your software. They want to just figure it out as they use it. This means your software needs to respect them. It should be easy for them to learn how to use it. Most importantly, it should be easy for them to correct any mistakes they will make.

Because, rest assured, your users will make mistakes. When the user no longer fears making mistakes they’ll enjoy using your software. And then you’ll start getting feedback that says: “Your software is so easy to use. I love it!”. Trust me, you’ll enjoy that, too!

Simple is Hard

Simple is Hard, as in “hard for you, the developer”.

To be blunt: it’s going to take a lot of work for you to create something that’s simple. You’ll spend significant time thinking and not actually writing any code. This can be difficult for a lot of developers. After all, they equate productivity with typing. But realistically you probably will spend more time thinking than coding.

When it comes to simplicity, your design matters. A lot. You can’t just bang out a solution, figuring it out as you’re coding. Sure, you’ll end up with something and it may even be useful. But it most certainly won’t be simple.

A really good reason to not spend a lot of time coding is so that you can be more flexible. If you come up with a new, better and simpler design, you’ll be more likely to throw away your old design if you didn’t spend many hours coding it up. It’s just a fact. We all get attached to the code we write.

Be simple. You will appreciate it.

Simple is Less

Less what?

  • Less stress for you
  • Less stress for your users
  • Less code to write, which means less bugs
  • Less features, but the right ones
  • Less complexity
  • Less buttons

But, believe it or not, it’s a lot more work to do less. As the famous quote from Blaise Pascal says: “This letter is very long because I had no time to make it short.”

Simple is More

Things that are simple are:

  • Used more
  • More useful
  • More fun
  • Bring you more customers
  • Get you more sales

So you can go on more vacations!

Simple is Efficient

By virtue of having software made simple, you gain a few efficiencies. Perhaps most importantly is the ability to release your software quickly. Frequent updates to software, particular when it is in the early stages are a great way to get user feedback, show your commitment and get people excited.

A common way to keep working efficiently on core features (and not bloated features that not everyone needs) is to build a way to allow your users to configure the software to meet their needs. This can range from simple preferences that the user can tweak to more advanced configuration files and plugin support.

What is Simple?

Simple doesn't mean just do less. It really means be focused. Know what you need to do by understanding your customers. Do what they need, not what they think they want. Believe it or not, these are often two very different things.

Customers don’t understand software; you do. It is your job to find out what they truly need to do.

Find Your Niche and add value, not features. Dare to be different because you don’t do what everyone else is doing.

Simplify Your UI

Eliminate ways for your users to make mistakes. This means provide some way for users to be able to "undo" a change. Design for the novice, but don't alienate your power users.

And don’t ask the user silly questions: Are You Sure about this or that?
Just make reasonable assumptions that the user can change (or undo) if they want.

Simplify Your Code

Only write the code you need, don’t write the code you might need. Less code means less bugs and less to test. You can always write it later, when you need it.

Refactor often as technical debt can kill even the best intentions.

And test often. Don't just "ship it if it built". Use unit testing, continuous integraton and try test-driven development.

Lastly, master your tools. Whatever tools you use be sure to master them so that you are as efficient as possible.

Software Made Simple with Xojo

If you like simplicity you might also want to check out development tools that themselves value simplicity. And Xojo does just that. With Xojo you can make apps for Windows, Mac, Linux, Raspberry Pi, iOS and the web from a single, focused and simple IDE and programming language. It might prove useful for your next (or current) project.

I think the short section about simple code cannot be stressed enough. I’ve met a couple of developers in my career that either do not understand the value of writing simple code or even worse, they think writing code that is very complex (or complicated) makes them a skilled programmer because others having a hard time to understand it.

Write simple code!
Write simple code!
Everybody, write simple code!

I personally find iPhones incredibly frustrating. You're so locked in to doing everything 'their way'. I've tried to help non-tech friends to solve problems they were having on their iPhones before, and I could barely work out how to use the thing. Android phones with stock (or close to stock) Android I have always found to be far more intuitive and easy to use.

Many, many things that are so easy to do on Android seem an absolute chore on the iPhone

I’ve not used stock Android, just the Amazon Fire OS variant which is not good. What is an example of something you’ve found easier on Android than iPhone?

The main thing would be sharing things easily between apps. This seems so limited in iOS after using Android

Gotta agree with your there. Sharing stuff between iOS apps is certainly a pain from both a developer and user standpoint.

Words of wisdom :) I like Rich Hickey's take on simplicity with the "simple is better than complex, complex is better than complicated".

A good reminder for all creators: developers, writers, engineers…
We should spend more time visualizing how our product will be used.
How it will affect the end user.
Any small optimization will potentially benefit thousands of users and their precious time.

The creation process burden should fade away so that only the product itself remains, hiding all the complexity underneath.

I'm usually stumped by Apple apps, even after having had to use one for years. The photo apps? baffling. I have to google how to do anything. iPhones? Insanely difficult to use.

As a tiny example, I gave my mother an ipod nano (the one with the click wheel) then they came out, and they didn't come with a manual. Next time I visited her I found she didn't use it because she hated the interface - turned out she'd been clicking the wheel top right left and bottom instead of moving her thumb around in a circle. Because - wait for it - there's no signifier and no manual.

Simple is good, however Apple's version of it is usually at the cost of usability.

It sounds to me like the problem is discoverabilty, not useability. Once you showed her the spin motion, all else is pretty simple. The spin motion was more discoverable on the original iPod because it actually spun.

But Apple's decision not to include manuals can only work when the product's features are discoverable. It's obvious once you've seen it, but if there's no system in place to let you see it before you use the device and no signifiers around the device itself, it's all down to luck.

K.I.S.S. - The mantra we should all strive to achieve :)

I've been a iPhone user for years. After having the iPhone4, I took a break and tried the Microsoft phones, and found them to be a breath of fresh air, except for the lack of specific apps. As a phone, it had all the core features, it was simple, and it worked well. After switching back to iPhone 6, Apple had added so many new features that it wasn't the simple phone I started off with years before, and I was a bit lost. If I was confused, I can only wonder how my senior citizen parents may feel after they inadvertently swipe from a edge of the screen, and see a view they've never encountered before. I feel Apple has crossed it and created something that isn't so simple anymore.

As for the Amazon Fire tables, I feel they were never simple to begin with. Maybe that's because I was coming from the iOS direction.
