It’s perfect

I can’t think of a single criticism. It’s exactly what I need regardless of the generation I’m playing at the time. And I switch between generations a lot.

Idea for next improvement: themes. Depending on which game is set as default, change the color scheme, fonts, background to match the theme of that game. Make it feel like a dex of that games era.

Too many adds, made it unusable

I used to love it, the bombardment of adds made it unusable

Perfect! Needs Update.

I absolutely love all of this! Just one problem, when using it to find out stuff for champions it isn’t that helpful since Pokemon changes over time but even though you seem to stick to the mainline games could you add champions as a game so I could get more info when building teams for myself? thanks! (Also Gmax Pikachu is missing even though it definitely exists.)

The Perfect Pokemon Champions Companion App…Except…

Except it doesn’t have the data for Pokemon champions, and thus I can’t use it for any of the new mega evolutions meaning I have to use a whole other app for those Pokemon, making my purchase of this one woefully unnecessary. I will update this as soon as this issue is fixed to reflect the otherwise brilliance present in the design of the app.

Great BUT…

This app is fantastic for tracking my various pokedex status from each game as well as saving my teams from certain milestones.

That said, this afternoon when I saved a team setup, two things occurred to me that need to be updated - the Stellar Tera Type isn’t an option, and my Iron Moth has Meteor Beam, but I wasn’t able to attach the move to it in the app. Minor things, but seems like it needs a slight update.

Otherwise, I love everything about it.
