iOS app for event production teams
Prevento HQ
A field-ready workspace for event site surveys: photos, measurements, annotations, audio notes, tasks, comments, participants, and PDF reports in one organized record.
Version 1.0.1 prepared for App Store review
Built for the venue visit.
Prevento HQ keeps the first walkthrough from becoming a loose pile of photos, voice notes, and chat threads. Each event has a structured record the team can return to during planning, setup, and follow-up.
Record walkthrough notes, transcribe Spanish audio, and keep the transcript next to the event record.
Invite clients, vendors, and team members with event-level access and a clear permission audit trail.
Capture photos, audio, notes, tasks, comments, and edits without signal; sync them when the team reconnects.
