“With app or conference call solutions, users have to connect to an external server prior to recording,” Just in Case CEO Oshri Farhat said in a prepared statement. “In fact, most times you want to record, you don’t realize this in advance. With Just in Case, users can instantly record 100’s of hours of conversations whenever they want.”

Compatible with iPhone 5 or later, the Just in Case looks like your standard bulky smartphone case, except for two extra buttons: one to start and end recordings and a second to play them back. Rather than relying on an app that cuts into the call, the case opts for a comparatively low-tech solution: a small microphone placed in just the right spot to record both your voice and the sound coming out of the receiver. The microphone can also be used as a stand-alone audio recorder for in-person conversations.

If it looks a bit bulky, it’s because the recorder is powered by a self-contained battery and supports MicroSD card storage. The recorder’s battery can record for up to eight hours, and lasts for as long as a year in low-power mode. The device will come with a 2GB MicroSD card, which can be swapped out. Unfortunately, since these features are meant to minimize the recorder’s strain on the phone, they cannot be used to enhance the phone’s battery and storage.

The Indiegogo campaign is seeking to raise $30,000. Early bird customers can currently pre-order the recorder-case for $30. The case will retail for $60 at launch. Just in Case expects to ship the device to backers in May, 2016, though the timeline may change if the campaign does not reach its funding goal.
