Show HN: CertWarden – SSL certificate monitoring app for iOS

Hey HN! I'm the maker of CertWarden. I'm a DevOps engineer with 15+ years of experience, and I got tired of manually tracking SSL certificate expirations across dozens of domains — both my own and my clients'. Missed renewals causing downtime is a pain nobody needs. So I built CertWarden — a simple iOS app that monitors your SSL/TLS certificates and alerts you before they expire. The free tier covers up to 5 certificates, and Pro unlocks unlimited tracking. Tech stack: • Native iOS (Swift) • Backend running on Cloudflare Workers • Freemium model (5 certs free, Pro for more) What's next: • Web portal/dashboard • Webhook & notification integrations (Slack, Discord, etc.) • Bug fixes based on early user feedback I'd love to hear your thoughts, feedback, and feature requests. Happy to answer any questions!
