Half the battle is knowing the conference exists. A deadline tracker will not discover venues for you; that is not its job. Its job starts once you know the name.
- Discipline coverage first: a beautiful app tracking the wrong field is decoration - Alert quality: customizable lead times beat fixed ones - The boring metadata: locations, submission links, notification policies, all in one place - The app matters less than the database behind it; check when the venue list was last updated - Use a matcher to find venues, the app to not miss them
VenueFit is free: it is the matcher and the tracker in one, with venues, deadlines, and submission links current.
