Have you tried BitGo (https://bitgo.com)? BitGo is a theft-resistant wallet that uses multi-sig built on P2SH. 3 keys issued, 2 required to sign any transaction. One key is stored with BitGo, one with the user, and one offline. Security of multi-sig with the ease of use of online/mobile access.

We've published a whitepaper (https://www.bitgo.com/p2sh_safe_address) on our tech and open-sourced a lot of components. Our tech was built by a team compiled of veterans in online security and digital currency.

In addition to the security of multi-sig, our platform enables additional protections like spending limits, network fraud detection, and whitelist addresses. This means that you could design a specific-use wallet that can has limits on how much can be spent in a day or where you could spend your funds. If a thief took your wallet/phone, they would be stopped by these protections and you could move your funds to a new wallet later on.

Please give BitGo a try and let us know what you think! https://bitgo.com
