ViperGas

Great app for gas engineers with tons of handy info, well worth the money!

When you search it just go off which is annoying but otherwise great information and there also a search button

Such a great app, so much knowledge packed in one simple easy to use app! Even if you think you know the book inside out, always great to have at the touch of button to double check, solve and get on with the job! Worth every penny

Excellent App for the gas engineer, well developed for quick referencing at those times you need a little guidance on current industry regulations. Would highly recommend Viper Gas.

We finally have an app to go to for up to date information. This will be a great resource for anybody currently training to become a gas engineer and also for anybody who is already qualified. There is always a time when you need to find out information on a situation that you may encounter while out on the tools, and this is the quick easy option. No more outdated books in poor condition living in the glove box of the van. Great app!

The books are essential in achieving your gas qual as well as handy references for those already qualified. More importantly though I had an issue with IOS 17 and contacted them. Within couple of hours had an email explaining situation and would be informed when update available. Same day late evening I get an email letting me know the app has been updated and can be reinstalled. Brilliant customer service. Thank you folks.

Every now and then you need to double check something the app contains it all and the search option makes this so simple to find what you need! Love the app and layout! Easier to use than a book 🙌🏼

This is the go to app for all gas engineers. Everything on your phone and it’s all up to date. Good service from viper gas.

Finally a gas publication that’s made it to the 21st century. So amazing to have a resource book that’s searchable, interactive with clear quality pictures that can save pages as bookmarks too. Now I’ve always got my books with me. Nice one Viper

This is by far one of the best app that provide up to date gas books at the touch of a finger. Putting it on to the app has definitely made my life easier. High recommend this app 10/10 👍
