Only trusted devices can connect to ReVault. The data stored on ReVault is encrypted using AES-256. On top of that you can also choose to password protect the ReVault app using single, or 2-factor authentication. ReVault performs auto-backups and auto-synchronisation across your devices and supports Android, iOS, Mac OS X, Windows, and Linux.
ReVault is wearable (neck, wrist or pocket) so your files will always be close at hand. There are, however, currently only two storage options, 32GB and 128GB to choose from.
The case is stainless steel and the screen is made from Gorilla Glass 3, which not only makes it strong and durable, but also water resistant. The ReVault's battery will last around 3 days, and it uses a standard Qi Wireless Charger that's sold separately.
My primary concern is that the types of people who this will appeal to are probably early adopters, so they will almost certainly already own a smartwatch. It's unlikely that they'll want to carry around a second wearable device. What would be ideal, is if this technology was offered by the major OEMs such as Apple or Google. Rather than being forced to save all our data on the public cloud, it would be great to be given an option to save it to the private cloud.
It is very unlikely, of course, that Google would ever offer this, because their business model depends on us giving them access to our private data, to enable them to serve targeted advertising. Apple are more likely to offer this as an option, but as you'd expect from Apple, it would probably be a premium service based on a costly subscription. Yes you can manually back up your data using Time capsule, but what I'm talking about is a private cloud solution, like ReVault, that automatically syncs all your data across multiple Apple devices in real-time. If this service were ever to be offered by Apple, they would no longer be responsible in the event that your images got hacked. You and only you would be to blame!
The company's Indiegogo campaign is doing very well, and will very likely exceed its funding target of $65,000. If you'd like a ReVault, they are available to pre-order now for $199 (32GB), $299 (128GB). Estimated shipping date is January 2016. International shipping is available, presumably for an additional fee.
