The Lab Counter app is a generic counter app that does not restrict users to a set number of counters corresponding to pre-defined categories such as “live” and “dead” cells. Rather, when users create new experiments within the app, they can specify as many counters as they’d like per sample. These counters, in turn, can be named according to the user’s specifications. (Unfortunately, the editing process is a bit cumbersome. Rather than simply being able to tap on a text field to edit its contents, users must select the “edit” button. This gives a much more “computer,” rather than “iPhone,” feel to the app.) The counter “buttons” give the appearance of depression when you touch them and also “ding” upon being tapped, thereby providing visual and audio feedback that the counter is working. The final counters and numbers can be emailed as plain text.
