Five iOS options:

  1. WikiCFP (web): still the best CFP database, works fine in Safari.
  2. Conference Alerts (web/email): discipline-filtered alerts.
  3. OpenReview (web): ML deadlines and submissions.
  4. EasyChair (web): many non-ML venues run here.
  5. Whova: the conference attendance app, useful for scouting venues a year early.

Scouting trick: attend (even virtually) the conference you want to submit to next year. You will learn the community's taste faster than any app teaches it.

Screenshot interesting CFPs; calls for papers get edited after posting and dates sometimes move.

Nominate one co-author as deadline owner per paper; shared responsibility means no responsibility.

Portals, not screenshots, win deadline week. Sources: IEEE, ACM iOS is for discovery and alerts, not submission. When a CFP matches your paper, move to a real computer, read the call carefully, and put both deadlines in your calendar immediately.
