Domain Command

Features
Read full description

You have domains. They expire. This app makes sure you know before they do. Track your domains and SSL certificates in one place. Get notified before anything expires. No account, no server, no tracking. Buy it once, own it forever. DOMAIN & SSL MONITORING, FULLY ON YOUR DEVICE Domain Command performs WHOIS and RDAP lookups directly from your iPhone — no middleman server, no cloud processing, no data collection. Your domain portfolio stays on your device and in your iCloud, period. WHY DOMAIN COMMAND - Track domain expiry dates, registrar info, and nameservers via WHOIS/RDAP - Monitor SSL/TLS certificates — issuer, validity dates, and status at a glance - Get local notifications before anything expires — 30, 14, or 7 days out - All lookups happen on-device using public WHOIS and RDAP protocols - Works offline — cached data and pre-scheduled notifications need no internet - iCloud sync keeps your domains in sync across devices — still no server needed ONE-TIME PURCHASE. NO SUBSCRIPTION. EVER. Most domain trackers charge you monthly to run a cron job on their server. Domain Command has no server. WHOIS is a public protocol — your device queries it directly. That means zero recurring costs for me, and zero subscription for you. Pay once, use it forever. Free: track up to 3 domains with all features. Unlock the full app for unlimited domains, widgets, iCloud sync, CSV import, and per-domain notification settings. BUILT FOR DEVELOPERS & SYSADMINS - Information-dense UI inspired by mission control status boards - Domain names and expiry data in monospaced type — because they are data - Color-coded urgency: green (nominal), amber (advisory), red (critical) - Pull-to-refresh runs a full WHOIS + SSL check on all your domains - Batch add: paste multiple domains at once - CSV import and export for your records - Home screen widgets show your most urgent renewals at a glance NOTIFICATIONS THAT JUST WORK Notifications are scheduled locally via iOS. The system owns them once set — they fire even if the app is killed. Every time you open the app, it refreshes expiry dates and reschedules all reminders. Simple, reliable, no server ping required. PRIVACY BY ARCHITECTURE - No analytics, no tracking, no third-party SDKs - No accounts, no sign-ups, no email collection - The only network calls are WHOIS/RDAP lookups to public registry servers and optional SSL checks - One optional, opt-in feature: if the app can't parse a WHOIS response, you can choose to send the public registry record to the developer to improve parsing. That's it. No personal data, ever. - iCloud sync is Apple's infrastructure — the developer never sees your data SMART WHOIS PARSING Domain Command uses RDAP (structured JSON) where available, and falls back to WHOIS with format-specific parsers for major registrars. If a format isn't recognized, you can enter the expiry date manually and optionally report the format so it gets supported in the next update.
