About Arnold

Your Centralised Portal to Running a Successful Gym

Stingrae Database Services started developing Arnold in the late 1990s. Since then it has evolved several times and is currently supporting many successful Martial Arts businesses throughout Australasia.

As we are passionate about creating the best system possible, we often take requests from partners and code these features into the application. It's a community-built system!

We'll Help You Buy Members!

For every $1 you spend on advertising, you need to get back at least $1.01
But without a comprehensive tracking system there is no way to know if your marketing is worth it.
Read this blog post to learn more.

Mobile Phone Apps

Would you like Members to view their class history, or check in to classes via their phone?

What about sending them a Push Notification if a class is cancelled?

Both personalised iOS and Android Apps are included in the Gold Plan.

Integrations

Whether you are happy with your existing site, or we do it for you, you can integrate Arnold data.
Every plan (even Free) includes an online member sign-up page and a live “today’s classes” link for your site — cutting out annoying data entry!
Need something deeper? We'll quote custom integrations.
