I use reptile scan and I love it. Everything is stored on the website and used side by side with the android app. You can keep track of feed, shed, cleaning, pairing, ovulation, hatchlings, weight etc etc. It has QR code options so that each Snake can be brought up quickly on your phone/tablet.

I tried the iherp, but I prefer the simplicity and layout of the app better than using a website on my phone.

Also the hosting for the app / site is hosted on the same cloud servers as amazon, so it is highly unlikely of any data loss.
