SUPPORT THE BUILD

The Tip Jar

FUEL THE BUILD. I built Donkey Jaw Services to give the trades a digital advantage. I’m a solo developer bootstrapping these tools from the ground up—no corporate backing, just late nights and sweat equity. If Maintenance Vault or TrueMule Calculator helps you run your shop, track your gear, or protect your margins, consider throwing a few bucks in the tip jar. Every contribution goes directly toward server costs and keeping these tools running.

Frequently Asked Questions

Are Maintenance Vault and TrueMule Calculator free?

Our priority is keeping the core, everyday features accessible to the guys on the ground. As these tools evolve, we will introduce Premium tiers for commercial fleets and power users who need advanced, heavy-duty data tracking. For now, the tip jar helps keep the foundational infrastructure running for everyone.

When are the apps launching?

Maintenance Vault is dropping in June 2026. The TrueMule Calculator follows shortly after, entering Beta in Fall 2026. Join the waitlists on their respective pages to secure your spot for early access.

I have a feature request or found a bug. Where do I send it?

I build these tools for you. If you need a specific tracking feature added or something isn't calculating right, shoot me an email directly.
