Trust & Safety in the palm of your hand. • Input & Inspect. It's really that simple. Input a domain or IP address using the TLS Inspector app, or inspect any website from within your favourite browser using our Inspect Website extension. • No Nonsense Results. "At a glance" has never been easier. TLS Inspector will show you the entire issue chain for any website, and whether or not your device trusts that chain. • Dive Deep. Details for days. View important properties of any TLS certificate including fingerprints, dates, algorithms, and more. • Stay Safe Online. No training required. TLS Inspector makes it easy to detect and avoid man-in-the-middle attacks on unsafe networks by highlighting invalid and untrustworthy certificates. • Right Place, Right Time. Inspect nearly anything from anywhere. Easily access TLS Inspector from other apps, such as Safari, with the Show Certificates share sheet action. TLS Inspector is free & libre open source software (FLOSS) with source code available on GitHub. TLS Inspector is made entirely without the use of Artificial Intelligence (AI) or Large Language Models (LLMs).

SSL Certificate Checker helps you monitor SSL/TLS certificate health for the websites and services you care about. Add one or more targets (hostname + port, default 443), run a check instantly, or scan your whole list in one tap. The app is designed for a quick daily workflow: open, scan, review risk, and act. What you can check: - Expiry date and days left - Status classification: OK, Expiring, Expired, Failed - Issuer and subject - SAN (Subject Alternative Name) - Serial number and signature details - SHA-256 certificate fingerprint - SHA-256 public key fingerprint - Negotiated TLS protocol and cipher suite Key workflows: - Single target check for immediate troubleshooting - Full list scan for regular maintenance - Saved targets and latest results stored locally on device - Optional periodic background checks (can be turned on/off) Built for practical certificate operations: - Quickly identify certificates close to expiration - Compare protocol/cipher negotiation outcomes - Keep a simple watchlist for internal or public endpoints - Generate and review report-style outputs inside the app Security perspective for connected-device teams: - Includes TLS protocol and cipher suite visibility to support baseline security reviews - Helps teams spot weak or unexpected negotiated ciphers during routine checks - Useful as an evidence aid for internal security discussions and release readiness - Designed as a practical checker, not a complete legal/compliance assessment tool Regulatory context note: - In the EU, RED cybersecurity delegated requirements under Directive 2014/53/EU Article 3(3)(d)(e)(f) apply from August 1, 2025 for covered products - This app can support early HTTPS/TLS posture checks, but it does not certify compliance with RED-DA, EN 18031, or any other regulation/standard on its own Privacy and control: - No account is required to start checking - Targets and recent check results are kept locally for your routine usage - Privacy policy and terms are available from within the app Current release focus: - Core SSL/TLS checking flow and result parsing are available - Batch checking and retry flow are available - iOS background checks are best-effort (system-scheduled) - Multilingual UI foundation is integrated; some languages are still being refined This app is suitable for developers, operators, site owners, and anyone who wants a simple way to track certificate validity and TLS configuration from a mobile device.

Verdict
The clearest difference is ratings volume: TLS Inspector at 256 against SSL Certificate Checker's 2. TLS Inspector also leads on monetization model (free vs ad-supported). SSL Certificate Checker's advantage is review sentiment (100% vs 83%) and rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SSL Certificate Checker holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: TLS Inspector has 256 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 83% of TLS Inspector's written reviews are positive against 100% of SSL Certificate Checker's.
Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
