Find student competitions and keep your plans in one place with Causey. Search by location and category, save events, open venue directions, add events to your calendar, and set optional reminders. Chess has the most complete coverage; Debate, STEM, Arts, and Writing may have limited or no results. Parents can manage linked students, respond to invitations, and track the organizer registrations they complete. Coaches and authorized workspace staff can manage rosters, attendance, and results. Registration takes place on the organizer's website. Discover public clubs, request membership where eligible, and keep up with your connected workspaces. Report an event or club from its page, block eligible publishers, and manage blocked publishers in Support. Causey is for direct use by people ages 13 and up. Parents and guardians can manage younger children's profiles using their own accounts. Coverage is incomplete: confirm dates, fees, and eligibility with the organizer.

Verdict
The clearest difference is review sentiment: Causey.dev at 100% against Rank One's 18%. Causey.dev also leads on rating (5.0 vs 3.6) and update cadence (every 3 days vs every 2 weeks). Rank One's advantage is ratings volume (618 vs 6) and chart position (#81 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
