Xema offers fast user interface to save your records. You can manage your records, locations, species, persons etc. and import & export them with csv-format. While the main target when developing this app were finnish birdwatchers, it has now feature set that should serve anyone in Europe.
This way you can make backup of your data and save those for example to your PC.
Xema is approved by BirdLife Finland and is able to send records directly to Finnish Tiira web service.
