About

ConfiCheck

Features
Read full description

ConfiCheck contains information about upcoming Java related conferences. If you either attend or speak at a conference, you can select it per conference. You can select 'All' conferences and it will show you all available conferences this year with the current month opened. When selecting 'Speaking', the app will only show you the conference where you will speak at. If a conference 'Call for Papers' is open, you will see a specific row that says 'CFP' that also contains the link to the call for papers and also the date the call for paper will end. This date will be colored depending on the days the cfp is still open. Each conference entry also contains a link to the website of the conference and a link that will open the location of the conference in the Apple Maps application. You can add your speaker info like name, bluesky account, bio and experiences (e.g. conferences you have spoken at) and share this information which is useful in the CfP process. The app allows you to add all your available sessions and keep track on where you proposed a session and what the state of the session is. You can also add conferences to your calendar.
