If you have been in a situation in which you desperately wish you could go back in time and hear something again, then you are in luck. Here is an app called Heard that can record anything that your iPhone’s mic picked up, up to 5 minutes back. The slogan of this app itself is quite explicit: “Turn your iPhone into a time machine!”
Heard starts working as soon as you open it, by capturing everything through the mic. It stores the sounds into a tiny buffer that can store up to five minutes of audio. It simply refreshes to include fresh audio from the surroundings. Whenever you want to store something you heard, you simply push the big button to save.
All those snippets of conversation you saved will be available in the library from which you can share it on Facebook or by email.
The app can listen from the background and can set the buffer size to 12 seconds, 30 seconds, one minute, or five minutes.
This is quite a useful app for most people. If you simply want to prove that you heard someone right in a conversation or a debate is one of its pretty awesome uses. How many times has it happened to you that someone simply made a stupid remark and two minutes later that person simply denied making it? You could turn time in your favor with this app.
Thanks to the Heard app, such embarrassments will no longer happen. Also, you can simply tag any audio file that you record and share it with your friends via social media. Thanks to TechCrunch for pointing out this highly useful app. The only disadvantage is that the app is currently available only for the Apple iPhone; whether or not it will be made available for Android in the near future is unknown.
