About Frightfolio: HHN Tracker
Frightfolio is an independent fan app for Halloween Horror Nights at Universal Orlando, with the Hollywood event added in version 1.3; it isn’t affiliated with Universal. Check in when you arrive and log each house as you come out, then rate it and note how scary it was and how long you waited. It keeps one rating per house per season, ranks your seasons, prints a ticket for every night, adds up what the season cost, and fills a passport with a pin for every house. There are live wait times, a plan for the night built around the lines, logging from Apple Watch, and every Orlando season back to 1991; an optional account adds reviews, posts and following other fans. It’s free, with no ads or tracking, and runs on tips.
The Frightfolio roadmap lists iPhone Duo support as shipped in version 1.3: open the Duo and the app spreads across both halves, with the passport reading like a book. A night board for the Duo, with tonight’s lines, your plan and your count at a glance, is planned. Matthew Tucker lists the app for every pose, from closed to Split View, without describing the other layouts.
