It's now easy to share or delete multiple strip charts at once. Just hit the "Select" button or swipe with two fingers across the charts you want to select, then choose an action from the toolbar. Sharing fotos and strip charts is now also possible via the Messages app, and several bugs are fixed to improve overall stability.

Some small improvements to make the app even more enjoyable.

In the event of an error, the report that can be sent to the developer contains better details to help resolve the issue.

This version fixes a bug that prevented some paper strips with annotations to be deleted permanently. It also improves the experience when adding annotations.

A few crashes are fixed in this version and a glitch is removed when launching the app.

It also includes all the improvements introduced in version 2.1.3:
This version fixes several issues with requesting permission to access the microphone, back camera, and storing images to the photos library. Also, the in-app store is updated to properly display the preview video again.

Strip charts are now even easier to delete by swiping them left or right and two new buttons make switching between gauge display and strip chart recorder more clear. You may still just swipe between those two views.

And maybe you notice, the camera now opens very smoothly and quick.

Thank you for using Decibels. I'm always happy about positive reviews and comments.
