Great app

Great app just needs to speed up a bit would be great to be able to put company logo on the pre start aswell.

Is there a way to turn the Pre-Start into a PDF file it has potential to be an amazing app.

Not all machines are listed but was able to get really close to what I needed. Would be nice to also add In more attachments or even an option to add it in our selves.

For multiple operators would be good to be able to manual pin machine on gps similar to apple maps when you park your car. Same for attachments so you could check in or out items so you know which operyhas what gear on what site.

Would be happy to pay a yearly subscription for bug fixes and improvements but so far big thumbs up.

Crash an burn hey mav

Is the head designer of this app a potato?
If it’s not crashing it won’t load. Frustrating
Otherwise great idea
