IP Scanner & Service Watcher vs UpdateContacts

IP Scanner & Service Watcher is a field toolkit for IT support engineers, network administrators, CCTV/camera technicians, and home lab users. Diagnose the network you are connected to, discover LAN devices, check open ports, inspect TLS certificates, resolve DNS, run ping/traceroute, and watch important services from your phone. KEY FEATURES - LAN discovery: scan the current subnet or a custom CIDR/IP range and review device IP, MAC, vendor, online/offline state, and open-port status. - Port scanning: use focused profiles for IT, servers, network devices, and CCTV systems, or enter custom ports and ranges. - Multi-instance tasks: run ping, LAN port checks, WAN checks, traceroute, and loop scans side by side, then jump back to each live task from the running-task badge. - WAN visibility: detect public IPv4/IPv6 and check public port reachability through an external probe. - Network tools: Ping, DNS Lookup, Traceroute, Website Check, Site Alive, Endpoint Health, Content Match, SSL/TLS Check, Domain Expiry, Subnet Calculator, Wake-on-LAN, and MAC vendor lookup. - Service Watchers: convert supported tool runs into recurring checks with healthy/failing/recovered states, thresholds, cooldowns, history, and optional notifications. - Clear diagnostics: TLS, HTTP, DNS, TCP, IPv6, and OS-level limitations are reported clearly so field work does not stop at a vague network error. The app is designed for networks and systems you own or are authorized to test. It is not a nearby Wi-Fi/SSID scanner, Wi-Fi analyzer, wardriving tool, VPN, proxy, or broad internet scanner. No account is required for the core scanning tools.

From 4 September 2026, every mobile number in The Gambia changes. A two-digit operator prefix goes in front of the seven digits you already know, and the old numbers stop connecting. If you have a few hundred contacts, fixing them by hand is a long evening. If you have a few thousand, it is not realistic at all. UpdateContacts does it in one pass. SCAN UpdateContacts reads the contacts on your phone and works out which numbers use the old format, and which operator each one belongs to. Numbers that are not changing — Gamtel landlines, short codes, USSD strings and international numbers — are left alone. PREVIEW You see every single edit before anything happens. Old number, new number, contact by contact. Nothing is saved until you confirm. UPDATE Every number is changed in one go. An encrypted backup is written first, and one tap puts everything back if you change your mind. FOR INDIVIDUALS AND INSTITUTIONS The number update is available for both individuals and institutions, public and private. A business, ministry or school with thousands of numbers in a shared address book runs exactly the same flow as one person with their own phone. The bulk update, the encrypted backup and the undo do not change with volume. FREE TO SCAN AND PREVIEW Scanning, previewing, the single-number converter and the migration information are free, and always will be. A one-time unlock adds bulk updating, encrypted backups, restore and undo. No subscription and no repeat charges. YOUR CONTACTS STAY ON YOUR PHONE The scan runs entirely on your device. Your address book is never uploaded — there is no server involved in scanning at all. UpdateContacts never asks for your phone number.
