Twitchin is an app for birdwatchers. With one simple tap it will record all the information a twitcher needs to allow them to identify a bird.
1 twitch = 1 sighting
Birdwatchers like to identify birds that they have seen.
Consult a bird watching guide
Either in the field or when you get home.
In the field:
Birdwatchers like to make lists of the birds they identify, to keep a record of all the birds they've seen and where they've seen them.
Make a list in a notebook or on the computer
Post-field trip - in the home, or hotel. Per field trip.
Responsive app would not be suitable because the app needs to be used in context e.g. in the field. It would be possible to have a desktop version that would be used for editing and sharing lists only, however realistically, this is beyond the scope of this project.
