Hi,
IGFA is now selling an iPhone application via App-store; "IGFA Mobile":
http://www.igfa.org/Fish/IGFA-Mobile.aspxPersonally, I consider the IGFA website difficult and slow to use, so the functions offered in IGFA Mobile are definitely a great improvement. Beside world records (nice list of line classes etc.), the species descriptions are very useful - although slightly heavy regarding text volume for each species. A personal log for catches (including photo- and GPS/mapping functions) is also included in the package.
Price: 10 USD (?) - not sure since I paid in Danish Kroner.
And for the record - I have no personal interest in promoting IGFA products. Just find the “iFishing” apps useful during fishing trips (knots, GPS, weather forecast etc.)
Best wishes,
Dan
