Rock Picker app for iPhone and iPad

Using Rock Picker you can precisely mark where rocks or other obstructions are while you are out working your fields. Later someone can return and use the app to locate the rocks and mark them off after they are "picked" out of the field.

* Can use internal positioning data, or supported Bluetooth GPS devices can be used.
* Dropbox is used for syncing data between devices, including to and from other versions of Rock Picker.
* Accurately mark rock location in relation to the trailing field implement, with customizable offsets for implement dimensions.
* Group rock markers from different fields into separate sets.

The app is limited to marking 2 rocks and Dropbox syncing is blocked, unless a $49.99/year auto-renewing subscription is purchased. This will be billed through your iTunes Account. If you wish to discontinue the subscription you must turn off auto-renew at least 24 hours before the end of the current period. Subscriptions can be managed through Account Settings.
