Time clock is off in graph display

Strange bug when you enable Alternative Time Display to enable time clock in graph display. It shows the time under the graph from the moment you press stop, not from the time you press start.

So the time under the graph is always offset by the time recorded.

For example, you start recording at 9:00pm and stop at 9:05pm, the time under the graph shows you that you started recording at 9:05 pm and ended at 9:10pm. If you record for a few hours, same thing.

As of now, it’s a useless feature. My guess is the graph uses stop time as an input instead of start time.

This has been mentioned before in the review. Still not fixed for Apple devices.

Also, location address changes to neighbouring buildings, it would be nice to input your own address.

Great for noise measuring

This is one of the better noise measuring apps that does continuous measuring and shows the results on a graph. The graph image or results ( in csv format) can be exported. Measurements can be saved for viewing or exporting later on. The only issue which may be intentional is when Calibrating it doesn't member the adjusted setting next time the app is used so have to calibrate again. The option to save the Calibration setting might be useful. However still a very good app.

Clock not showing correctly in recordings

Accurate time is very important when using these recordings as evidence. Time showing on recordings is hours out.

Great app ruined by incredibly inconvenient sharing feature

I don’t understand how they could’ve put this much work into making such a great app, and then made it virtually impossible to get the videos off your phone, by requiring you to export them one at a time through a sharing feature that requires multiple clicks per video. i’ve got about 50 videos saved and it’s a nightmare tried to get them off the phone. They could easily have implemented iTunes file sharing so it was possible to just download the videos from the app through iTunes, or save them to the camera roll, or you let you select a bunch of them and upload to dropbox or save to iCloud, and they didn’t bother to do any of that. It would’ve been a five star app if not for that, but 1-by-1 export via a clunky “Sharing“ interface is such a major hassle and such an obvious missing feature that I’m deducting two stars for it.
