Hi I am a new mac app developer, and i just got my first app in the Mac App Store. It's name is iExifer, and it's an EXIF metadata viewer for jpg images. Currently it supports EXIF, EXIF manufacturer notes for several camera makes, gps location and exif thumbnail visualization. My plan is to add support for more file formats and metadata types in future releases, and also i am trying to add support for more camera make specific tags. Just Released version 1.3, with a great new interface. Browsing pictures in your computer now easier, faster and more convenient. New Promo Codes (Aug. 31st): in this post Since it's my first app, if you get one of the codes, i would really appreciate any feedback or suggestion to make it better.
