Text Message App that have "Save as Draft" feature?

[roundabout]

Hello, Im look for an free text message app that have this feature like in the android default message app, You type in a message then pressing the back button then it save as anonymous draft. I tried many apps such as EvolveSMS, Chomp SMS, Textra SMS, MySMS and none of them doesn't have this feature.

I have EvolveSMS and pressing back saves it as a draft. I do have the full paid version though, so I'm not sure if the free version has it.

I'm using Handcent SMS which does this.

Pressing the back button in both Messages and Hangouts save the message as draft, so I expect that they all do that.
