SSL Checker is designed for cybersecurity enthusiasts and website owners who have websites with Secure Socket Layer certificates installed. With this app, you can quickly check the current SSL status of any host. If there are any issues with the certificate, the app will inform you of the problem. It can identify if the certificate is self-signed, not issued for the checked host, or expired. When you check a host, you can also start monitoring it. By monitoring, the app will detect any changes to the host’s certificate and track its expiration date. If an SSL certificate for any monitored host is about to expire, the app will send you a notification to remind you to renew it. This way, you can eliminate the risk of forgetting to renew the certificate for your host on time. FEATURES: - Validates SSL quickly - Monitors selected hosts for SSL issues - Notifies when SSL is about to expire SSL Checker is a simple yet powerful iOS app designed to help website owners avoid unknowingly or accidentally letting their SSL certificate expire. With the increasing use of SSL to secure the web, keeping track of certificate expiration has become a growing concern among developers. This app takes that headache away by notifying you when the certificate for any of the hosts you are monitoring is about to expire. Additionally, it color-codes the hosts whose SSL certificates are nearing expiration, so you know when it’s time to start worrying about renewal. While many SSL issuers currently notify hosts, these notifications are usually sent via email. With the large number of promotional emails these issuers send periodically, it’s easy to overlook or ignore the important emails containing SSL expiry notices, which can result in the SSL certificate expiring. To prevent this, it is highly recommended to use this app as a backup for receiving SSL expiry notifications. We hope you find this app useful.

NanoIP

NanoIP shows the public IP address your iPhone is actually using — IPv4 and IPv6 together — and says plainly how your traffic is reaching the internet. EVERY APPLE DEVICE NanoIP runs on iPhone, iPad, Mac and Apple TV, with a free Apple Watch app. The appearances are one purchase that unlocks on all of them, and your exit history follows you through your own iCloud. ON THE MAP See where your exit surfaces. A soft disc over the country when that is all the on-device database knows; a point when you switch city lookup on. Both address families, and a line between them when they surface in different places. Positions come from the address, never from Location Services. HISTORY Every change of exit is kept — a new network, a VPN coming up or going down — as a timeline, a map of every place your exits have been, and a “Passport”: countries, networks, time spent on VPN. Stored on your iPhone and, if you like, in your own iCloud private database, which nobody else can read. Delete a row or clear it all at any time. THIS DEVICE Your side of the connection, drawn as a path: device — interface — tunnel, if there is one — gateway — DNS — exit. Then every interface that has an address, with each address labelled global, private or link-local, and the path's own flags: IPv4, IPv6, expensive, Low Data Mode. No permission asked; nothing here leaves the device. LOOK UP ANY ADDRESS Type an IP address or a domain: country, network, reverse DNS, whether it answers on port 443, and its place on the map — against the same offline databases. SHARE IT One tap turns the exit into a card made for a chat: the address large, the country and network, a map of where it surfaces, the time, and the app’s name. Privacy mode masks the address and drops the map before anything leaves. TOLD WHEN IT CHANGES Turn on alerts and NanoIP notifies you when it notices a different exit — best effort, whenever iOS lets it check. APPLE WATCH Your exit on the wrist: the address, where it surfaces and the latest changes, sent from your iPhone. Four complications and a Control Center control. Free, like every widget. WIDGETS, EVERY SIZE, FREE Small, medium and large on the Home Screen. Circular, rectangular and inline on the Lock Screen. StandBy on the nightstand. A one-tap control in Control Centre. Every size is free, and stays free. RESOLVED ON THE DEVICE Country and network are looked up in a database that ships inside the app. Your address is not sent anywhere to be identified. No account, no ads, no tracking, no subscription. IPv4 AND IPv6, SIDE BY SIDE Most tools show one of them. NanoIP shows both — and when one is missing it says which is true: that this network does not carry it, or that nothing answered. Those are different facts and they deserve different words. KNOW YOUR EXIT NanoIP reads the local network path to tell whether this device is going out through a VPN or a proxy, and labels an exit that belongs to a hosting network. It describes what it sees. It never tells you that you are “safe” or “at risk”. PRIVACY MODE Mask the second half of every address — everywhere, or only where a screen can be read over your shoulder. Copying still gives you the whole address. SIX APPEARANCES System is free. Dot, Passport, Boarding Pass, Terminal and Aurora are one optional purchase. Each is a different layout and typeface, not just a different colour, so they stay recognisable even where the system flattens colour away. You can try them for 24 hours before deciding. One purchase unlocks them on iPhone, iPad, Mac and Apple TV; Apple Watch has its own design. CITY LOOKUP, IF YOU WANT IT Off unless you turn it on. When on, NanoIP asks its own server for the city, time zone and network type behind your address. It is the only request that ever carries your address off the device, and it is yours to switch on. One purchase, no subscription. Questions or ideas are welcome — the address is in Settings.
