I'm Simon Haynes.
Welcome to
Spacejock Software

On this site you'll find my free software including favourites like yWriter, yBook, FCharts and more.

Are you looking for a freelance programmer? I occasionally take on additional projects, conversions, etc.

I'm also an author, with five sf comedy novels in print (details, Kindle) and a junior science fiction series for ages 8+ (details, Kindle).

I think they call that multitasking. I call it a lot of work.

Why Free?

Sleight Of Hand

Sonar3 Registration

If you use Sonar3 regularly you're encouraged to register. The more people register, the more time and resources I can devote to improving the software.

Once five people register I'll add an oft-requested feature: display multiple submissions for the same work. (No idea how, but I'll do it.)

Gold registration also entitles you to discounts on my manuscript evaluation and ebook creation services ... see the FAQ below.

Sonar3 Registration from $11.95

After payment your code will be sent automatically via email.
Any problems, please contact me
Registration Type

Frequently Asked Questions

I thought Sonar3 was free?
It is, and registration is optional. It's just a way of showing your support.

Why start charging now?
I'm not. I'm encouraging people to contribute but there's no obligation.

If I pay, will you add feature X?
The more people who register, the more time I can devote to the program. I can't guarantee I'll add specific features but every bit helps.

Why is registration only $11.95? Isn't Sonar3 worth more?
You're not buying the software, you're supporting the developer.

I made a donation in the past. Doesn't that count?
Yes, and I appreciate it. Unfortunately I don't have any way to link up past donations with the new registration system.
However, if you donated $11.95 or more in the past just email me your Paypal receipt and I'll send you back a registration code.

I don't have any money/can't make a payment. Will you keep nagging me?
Absolutely not. Sonar3 says 'Unregistered Version' in the main screen title bar (after the author and novel information.) That's it. No popups, no adverts, no opening of unexpected browser windows.

What do I get when I register?
You get a serial number which you can enter into the program, converting it into the registered version.
In future it's possible registered users will have early access to beta releases.
There may also be new and extended features which will only be available to registered users.
But for now, you're just showing your support and helping me to improve the software.

Gold? Silver? What's the difference?
Gold members are entitled to a discount on my manuscript evaluation service.
They also get a discount on my ebook creation service.
Keep an eye out for more benefits in future.

If I pay for Silver now, can I upgrade to Gold later?
Yes, I'm sure I can work something out.

This sounds too commercial for me. I'm off.
Look, some people will be annoyed about 'Registered' versus 'Unregistered' software, but I promise you're not losing any functionality. Many 'free' programs include pay-per-install toolbars, adware and other rubbish and Sonar3 has never done that - and never will.
