AfterLid is the iPhone companion for long-running work on your Mac. Check that your computer is online, healthy, and still working—without opening the lid or being in the same room. SEE YOUR MAC FROM ANYWHERE • View live Sleepy, Awake, and Always On status • Check online state, lid state, battery, power source, thermal pressure, and safety limits • Follow high-level AI agent activity and see when work needs your attention • Track usage windows from supported AI provider connections • Link your Macs to one account and switch between them • Use Home Screen widgets for quick status and mode access CONTROL POWER MODES Sleepy returns your Mac to its normal power behavior. Awake prevents idle sleep while the lid is open. Always On keeps eligible work available with the lid closed, within strict safety limits. Your Mac always has the final say. Battery, thermal, heartbeat, and session-duration safeguards can stop an Always On session automatically. MAKE IT YOURS Choose a character whose animation follows your Mac’s current mode. Browse approved characters in the marketplace, switch your active character across linked devices, or use Pro to create and import a validated character pack. FREE AND PRO Free includes live read-only Mac status, one supported usage connection, and access to saved characters. AfterLid Pro adds remote mode control, agent activity, all supported usage connections, and character creation and import. Eligible accounts can try full access for seven days. PRIVATE BY DESIGN Your AI prompts, commands, project paths, work files, and provider credentials stay on your Mac. AfterLid only relays the sanitized status needed to show health, activity, usage, and requested controls. REQUIREMENTS Install AfterLid on your Mac, sign in with the same account on both devices, and approve the Mac link once. Remote features require an internet connection.
JSON Master
Read full descriptionHide full description
JSON Master is a native JSON editor built around what you actually do with JSON every day: find the value, copy its path, understand what a field really contains — and fix the file when it doesn't parse. See the whole document as a tree and as colour-highlighted source, side by side on iPad and Mac. Both are the same file: change one, and the other follows. FIND YOUR WAY • Command palette: type a few letters and jump to any node or run any command — "custcity" finds customer.address.city • Breadcrumbs, back and forward after every jump • Search keys and values, step through matches • Full keyboard navigation on Mac and iPad UNDERSTAND A VALUE • Unix timestamps shown as readable dates • JWT tokens decoded: header, claims and expiry • base64, ISO dates and URLs recognised on sight • Warnings for integers too large for JavaScript • Collapsed branches show their first keys, so you often don't need to open them QUERY, COMPARE, GENERATE • JSONPath queries with live results — tap one to jump to it • Compare two documents by structure, not by line breaks • Generate Swift Codable, TypeScript interfaces or JSON Schema • Summary with node counts, depth and findings worth a look FIX AND EDIT • A broken file shows the exact line and column of the error • One-tap repair for almost-JSON: comments, trailing commas, single quotes, bare keys • Edit keys and values, change types, add, duplicate and delete — every edit undoable • Format, minify, sort keys, expand embedded JSON strings, convert JSON Lines • Copy paths in six notations: dot, JSONPath, brackets, jq, Swift and JSON Pointer MADE FOR LARGE FILES Files of tens of megabytes open without freezing, with progress shown while they load. YOUR WAY Four themes — Midnight, Graphite, Amber CRT and Daylight — and seven languages: English, German, French, Ukrainian, Spanish, Japanese and Portuguese. No account, no ads, no tracking. Your files stay on your device. LEGAL • Privacy Policy: https://vybgss.github.io/json-master-docs/privacy-policy.html • Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is device support: JSON Master at 3 against Afterlid's 1. On price, ads, in-app purchases and iOS requirement there is nothing between them.
