Add MetaData edit.

I got this app to better organize an audiobook. I like all the options, Sequence, Find and replace, nice job. I see that all the Metadata is loaded, but I don’t see a way to edit that. I think adding that capability would make this a great app worth far more than the $0.99 you charge. Based on the price of other Metadata editors.

Does everything I need, easily. Great support!

I've been reviewing apps with functionality to easily edit filenames in large batches. Mass Rename does exactly what I need it to do. It's simple, straightforward, and easy to use. When I have questions regarding the app, I reach out to George for support, and he alway gets back to me the same day - usually within a short time of sending a message. I think this app and his support are excellent. I'd recommend this app over other better known app names.

dissapointed for photo renaming

I bought this because it said it gave you access tp image exif data which I use to pull the shooting date, camera model and a few other things out that help me identify which camera I used. the xif data that’s available is basically worthless and only like 5 things are available and are on the far end of desirable. The next issue is that I add the date and time which this does but only goes down to the second… most people miss this but cameras take more than 1 picture a second and so it really needs milliseconds as well.

Adding these should be a pice of cake and I wrote developer but…. No answer… go figure.

I guess its time for me to start building usable apps
