About

Pry JSON Viewer

Features
Read full description

Here's the iOS version: Pry โ€” Native JSON Viewer for iPhone & iPad Pry is a fast, lightweight JSON viewer built natively for iOS. No web views, no compromises โ€” just a native binary that launches instantly and handles your JSON with zero overhead. Paste and Explore Paste any JSON from your clipboard and immediately see it rendered as a collapsible tree. Keys are bold, values are color-coded by type: strings in green, numbers in blue, booleans in orange, and null in gray. Arrays and objects show their item count at a glance. Navigate with Ease Tap any node to expand or collapse it. Pinch-to-zoom and smooth scrolling make it easy to work through deeply nested structures. Nested objects and arrays display with clear indentation and matching closing brackets. Expand all or collapse all with a single tap from the toolbar. Search Across Keys and Values Tap the search icon to instantly filter across all keys and values. Match count updates in real time as you type, and previous/next buttons let you jump between results. Built for Developers Pry shows node count, byte size, and parse time at a glance. Long-press context menus let you copy keys, values, and paths. JSONPath display (e.g. $.data.users[0].name) gives you precise navigation. Long strings are truncated to keep the view clean. Open JSON files directly from the Files app, Safari, or any app that shares .json files. Fast by Design Pry is compiled to a native binary using the Perry framework โ€” TypeScript compiled directly to machine code. It launches instantly, parses JSON in under 1ms, and uses minimal memory. No runtime, no interpreter, no garbage collector.

About

Open Adaptive Switch

Features
Read full description

Open Adaptive Switch is the companion app for a do-it-yourself Bluetooth accessibility switch. It lets a caregiver set up and manage the switch from an iPhone or iPad, with no cables and no computer. Please note: this app requires the matching hardware. Open Adaptive Switch is an open-source switch that you build yourself from inexpensive parts (a Seeed XIAO nRF52840 board, a button, and a small battery) for roughly ~$15. Full build instructions and firmware are free at github.com/mikavj/open-adaptive-switch. Without the hardware, the app has nothing to connect to. The switch works with iOS Switch Control, so a single button press can tap the screen, run a recipe, or drive the scanner, giving people with limited mobility an affordable way to use an iPad or iPhone. With the app you can: Choose the key the button sends, from a full list including the F13-F24 keys that pair cleanly with Switch Control, plus letters, numbers, and common keys, with modifiers. Switch between single-key, tap-or-hold, and short/medium/long press modes, so one button can trigger up to three actions. Set how long the switch waits before it sleeps to save battery. Rename the switch and pick a color in the app to match the button you built. See the battery level and charging state, including in the list of nearby switches before you connect. Install firmware updates over Bluetooth, choose any released version, or roll back if needed. The app collects no personal data. It uses Bluetooth to reach your switch and contacts GitHub only to check for firmware updates, which you can turn off. Open Adaptive Switch is free and open-source, built to make assistive technology affordable for families, classrooms, and anyone who needs it.
