1. You will not need Internet access for the app. This means you can use it on a plane (following all the FAA and airline rules first, e.g. turning Airplane Mode on and waiting until you are cleared). You can also use it on vacation, in the field or anywhere you don't have Internet access or don't want to pay for large uploads and downloads on your network.
2. To use this app, you have to enable Location Services for it. This is an Apple requirement. The app does not use your location data.
3. You will also have to turn Auto Lock to Never in Settings->General. This is also due to Apple. Remember to turn it back afterwards.
4. The app will tell you the type of each input file. If you choose a bunch of non-RAW photos, or RAW photos that are not supported, then an alert will tell you so.
5. A progress bar will keep you informed of the status of the work. When the app is done, an alert will tell you how many TIFFs, PNGs and JPEGs were written to your Camera Roll. The Photo App will take a few seconds after that to render the newly-created files.
6. The output files are written to the Camera Roll. Your original RAW files will not be affected.
7. This software is based on DCRaw without the restricted functions (no license) and ELCPickerController (MIT license).
8. If you have problems, please submit your logs and crash logs. We have received none so far.
