As answered by people managing GymMaster and Cert Decoder.
GymMaster's answer
We're the only gym management system that comes with 24/7 bluetooth gym door access out of the box instead of requiring clients to work with a third party. Truely the one gym app to replace your whole club management stack.
GymMaster's answer
If you want to set your gym admin on autopilot and offer the most streamlined experience for your members, then GymMaster is the one for you.
Instead of plugging multiple systems together and requiring you to manage (and pay for) several different apps, GymMaster includes everything under the one roof. Offering a vastly more powerful club management tool at a fraction of the cost.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
GymMaster's answer
GymMaster's built to be the world's most flexible gym management solution, priced competitively to support new clubs starting out, but built with the scalability and customisation to suit even the largest franchises with thousands of clubs. We work at both ends of the gym business spectrum and everything in between.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
GymMaster's answer
Originally started in 1996, GymMaster was built from the ground up to support local gym owners looking for a way to cut back on gym admin and was one of the first to offer door access in conjunction with membership management.
Over the years hundreds of thousands of hours of development and continuous improvement working closely with gym owners across 90+ countries, the system has grown into a powerhouse of club management and automation with a list of features and functionality that dwarf the competition.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
