Renewly: Cert & Domain Watch
Never miss a TLS expiry
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
TLS lifetimes are shrinking to 47 days. Renewly watches your certificates and domains and warns you 14, 10, 5, 1 days and 6 hours before they lapse.
An expired TLS certificate breaks trust in your site in an instant. A lapsed domain can lose it entirely. Renewly watches both, on your device, and warns you long before either one runs out.
Certificate lifetimes are getting shorter every year. Under the CA/Browser Forum schedule, the maximum TLS certificate validity drops to 200 days in 2026, 100 days in 2027, and just 47 days in 2029. Renewals are becoming too frequent to track in your head. Renewly does the watching for you.
WHAT RENEWLY MONITORS
Certificate expiry
A direct, on-device TLS handshake reads each host's certificate: issuer, expiry date, chain validity, hostname match, TLS version and serial. It reports the expiry even when a certificate is already expired or invalid.
Domain registration expiry
Renewly looks up your domain's registration expiry through public RDAP and WHOIS registries, so you are warned before a domain itself lapses, not just its certificate.
ALERTS THAT REACH YOU IN TIME
Renewly schedules local notifications 14, 10, 5, 1 days and 6 hours before each expiry. There is no push server in between, so alerts fire on time even if you never open the app. A background refresh and a re-check on launch keep renewals and changes up to date.
BUILT FOR APPLE PLATFORMS
- Home-screen widget showing the most urgent domain and its days remaining
- iCloud sync across your iPhone, iPad and Mac through your own private database
- Native iOS, iPadOS and macOS app, no web wrapper
- Monitor public sites and internal or private-network hosts alike
PRIVATE BY DESIGN
Renewly has no backend server and no account. Your watch-list never leaves your devices for ours, because we have none.
- No sign-in, no account
- No analytics, no advertising, no third-party SDKs, no tracking
- Domains and certificate metadata are stored locally and synced only through your private iCloud database
- We cannot see what you monitor
SIMPLE, ONE-TIME PRICING
Every feature is in the free app: certificate and domain monitoring, multi-stage alerts, the widget and iCloud sync. The free tier covers 3 domains.
Renewly Pro is a one-time purchase that removes the limit for unlimited domains. It is not a subscription and never auto-renews. Buy it once and it stays unlocked.
WHO IT IS FOR
Solo operators, indie developers, freelancers and small teams who run a handful of sites and cannot afford to discover an outage after it has already happened.
Renewly is an auxiliary reminder and should not be your only safeguard. Certificate and domain data depends on registry responses, the network and OS background execution.
