I would assume you would just need to "Request access" and then wait hopefully for someone to grant permission to you. I'm not really sure why it isn't just publically viewable, but maybe the creator(s) had reasons for having it private (insert helpless shrug).
This is a very old file from the early days of the Pocket Frogs Wiki. I do not think it is supported anymore. I use a work computer and cannot check the file. I am going to try to remove the link. DalekCaan1 (talk) 15:04, June 12, 2017 (UTC)
Hey guys, I know the spreadsheet you're talking about and I'm not sur eit's up to date. Additionally, those values were only for iOS. I've started an updated version for Android values here (https://goo.gl/uLX8tb) if anyone wants to contribute. If iOS people are having issues with their database, I'd be happy to copy and maintain a current iOS version as well, just let me know!
@Cjmlax: I am on iOS, and I have found no difference in values with your data. I added the rest of the Anuras and will try to keep adding more frogs data when time allows. Thank you for creating this database, it's awesome.
