A minimal and beautiful app to quickly find and copy universal symbols and their HTML codes. --Symbol Library------- • ISO-8859-1 • Reserved Characters: &, ', "", etc. • ISO 8859-1 Symbols: ¡, §, ¼, etc. • ISO 8859-1 Characters: Æ, Ã, etc. • HTML Symbols • Math Symbols: ∑, ∫, ⊕, etc. • Greek Symbols: Ψ, θ, etc. • Other Entities: ‰, ™, œ, etc. • Special Symbols • ⌘, ↩, ⌥, etc. --Equation Editor------- An equation editor can be found on the top of the table view. You can copy multiple symbols and they are added to the editor in order. You can also edit the equation using a keyboard, which also lets you easily copy it! Thus, you can compose entire equations in 'Simbol' and then copy them for use in another app. This doesn't take away your ability to copy individual symbols. When you tap the 'Copy' buttons in detail views, you get that symbol on your clipboard, in addition to it being added to the equation editor. :)

Scream O'Clock takes the chaos out of scare rotations. The app tracks each character’s groups so everyone knows when to be on set and when to take a break. No more guessing, no more squinting at a spreadsheet, and no more mental math at 12 a.m.—just clear countdowns and pocket buzz alerts when it’s time to switch. Features: Live Countdown – See exactly how much time is left before the next rotation. Pocket Buzz Alerts – Get a vibration alarm when it’s time to swap. Always in Sync – Everyone sees the same current rotation, no confusion. Dark Design – Fits the vibe of your haunt while staying functional. Built by scare actors, for scare actors, Scream O'Clock is your backstage tool to keep rotations smooth and the scares nonstop. App and Graphic Design By Hannah Wagner

Verdict
The clearest difference is rating: Scream O'Clock at 5.0 against Simbol's 4.2. Scream O'Clock also leads on update cadence (every 3 weeks vs every 6 months). Simbol's advantage is ratings volume (25 vs 4) and iOS requirement (7.0 vs 16.4). On price, ads, in-app purchases and monetization model there is nothing between them.
