Hew is a programming language built around actors -- lightweight, isolated processes that communicate through messages. If you've ever wondered what safe concurrency looks like without locks, mutexes, or data races, Hew is your answer. Hew Playground puts the full language on your iPhone or iPad. Write real programs in a proper code editor with syntax highlighting, auto-indent, brace matching, and a keyboard accessory bar for quick symbol access. The Hew compiler runs on-device via WebAssembly, so you get live error and warning underlines as you type -- no internet required. Long-press any identifier to see its type. When your code is ready, tap Run to execute it on the Hew server and see output instantly.

Verdict
The clearest difference is in-app purchases: Hew Playground at none against QR Code Inspector Devtools's 1. Hew Playground also leads on ads (none vs shown). QR Code Inspector Devtools's advantage is update cadence (daily vs every 2 months) and iOS requirement (17.6 vs 26.0). On price and device support there is nothing between them.
