It's basic, but it does the job. It could use better documentation aboute what privileges it need. There is a guide if you click support in the app store, but I wasn't able to find it through app itself. Also, once it has credentials, it seems to select the first domain and first subdomain it finds. I'd recommend setting it inactive before entering credentials, that way you can be sure it won't accidently override one of your records before you can configure it. Also, it puts an icon in the notification bar AND the tray. It'd be nice to be able to hide it from the tray. Lastly, I would improve the search terms in the app store. It doesn't include "route 53" which seemed obvious.

I set up a VPN server to my OS X Sierra Server at home, so I could access all my media files while on the road. The problem was my dynamic IP address kept changing and I had to wait until I got home again to find out what the new IP address changed to. I then had to manually update the IP address in the DNS records and then it would be fine until the next time. Now with this app running in the background, I’ll never need to think about it again. Every 5 minutes it checks and updates the records - very nice. Thanks for creating the app that is exactly what I was looking for!
