Apnea Comp is a professional competition management app for AIDA freediving events, built by ELfreediving for the people who run them: Organizers, Main Judges, Judges, Safety and Media staff, and Athletes.

Whether you are running a single pool session or a multi-day depth competition, Apnea Comp keeps results accurate, admin minimal, and everyone informed. • AIDA integration: import athletes and start lists from the AIDA system, then sync judged results back automatically for reliable official standings. • Event setup: configure Pool, Depth, and Team disciplines (STA, DYN, DYN-BF, DNF, CWT, CWT-BF, FIM, CNF), lanes, Official Tops (OT), intervals, break times, and multi-day schedules. • Check-in: register athletes with signature capture, handle late check-in and DNS, and apply automatic late handling. • Judging: enter realized performances (RP), award White, Yellow, and Red cards with penalty reasons, and use built-in distance and STA-average calculators, with unjudged athletes sorted first. • Live start lists: push start-list updates to athletes and staff in real time, and run Speaker Mode with a large countdown and audio cues for the MC. • Results and Rewards: rank athletes with configurable tiebreak rules, track WR, CR, and NR records, and export to CSV and XLSX. • Protests and re-swims: file protests under AIDA rules with athlete signature and jury decision, amend results automatically, and manage re-swim queues and openers. • Athlete Mode: give athletes their personal info, start list, results, rewards, in-app medical and liability forms with PDF export, and protest filing. • Built for every venue: English, Korean, Japanese, Simplified Chinese, and Traditional Chinese, with light and dark themes, Sign in with Apple and Google, profile photos, and account deletion.
