For legal, workplace-compliance or safety-critical measurements, use a calibrated Class 1 or Class 2 sound level meter.

About

stupid widgets

Features
Read full description

stupid widgets is a lightweight runtime for building rich iOS widgets with JavaScript — with a widget scripting API that is backwards compatible with Scriptable, plus a ChatGPT assistant that writes the code for you. Existing Scriptable scripts just run. Write a widget as a ListWidget script, render it in small, medium, and large, then pin it to your Home Screen as a live WidgetKit widget. Your scripts also run as Mac widgets, and iCloud keeps your whole library in sync across iPhone, iPad, and Mac. Describe the widget you want in plain English and the assistant writes it, compiles it, and runs it before declaring success. Nothing to set up — just type and watch it render. FEATURES • Scriptable-compatible widget scripting API — existing Scriptable scripts just run. • Rich widgets built with JavaScript: gradients, stacks, dates, text, and images. • Preview instantly in small, medium, and large families. • Bind any Home Screen widget to any script, per instance. • Mac widget compatibility — the same scripts run on macOS. • iCloud sync keeps every script in sync across your devices. • Generate or fix a widget with ChatGPT in plain English. • Fresh, isolated JavaScript runtime on every run. • Import, export, rename, and organize scripts with ease.
