LanScan 5.0 has been released, introducing the following enhancements:

Download it on iTunes -

Live Scan feature

Start icon gives now access to two kinds of scan

  • One Time Scan
  • Live Scan


  1. Live Scan will first intensively scan your network 3x in a row with ARP, ICMP (ping), DNS, mDNS and SMB requests to discover devices and resolves hostnames.
  2. Then an endless scan happens every 5s.

Enhanced One Time Scan

Before 5.0, the One Time Scan feature consisted of only 1 packet (ARP, ICMP, DNS, mDNS, SMB) per device.
Users were usually complaining of having to scan several times in a row to discover all devices of their network. Most of the time, ethernet (cabled) devices were discovered, but not wireless devices.

It occurred that wireless devices are often in sleeping mode to save battery, due to custom behaviour or 802.11 protocol for broadcast/multicast packets and needed several requests packets before answering.

Although this is interesting from a network analysis point of view to understand specific behaviours of some devices on the network, most users simply want all their devices at a first glance.

One Time Scan now consists of 3 scans in a row, although user will only see 1 scan: lazy devices have now more chances to be discovered after a single scan.

Notification on IP address change


This feature was already added to Debookee, and now LanScan also monitors continuously your network interfaces for IP address changes.
If so, it will popup during 10s, asking you to:

  • Keep LanScan results as is, without changing IP address
  • Clear all results and update with new IP address

Changes to Debookee

LanScan module embedded in Debookee will be updated soon with Live Scan feature, it already includes IP address change notification.

Migration from LanScan Po to LanScan In-App

LanScan Pro and LanScan In-App share the same code.
To be more consistent, we'd live to move our LanScan Pro users to LanScan In-App, for free, and seamlessly.

Checkout our message on Twitter -

We did not find any similar experience on the web, or if Apple will allow us this move, plan is to:

  • Upgrade LanScan Pro to 5.1 with a new menu for migration
    • We're currently stuck in how could we prevent users from buying LanScan Pro, except a warning message on AppStore: setting a high price?
    • Or can we configure an app to be only available for updates, not for purchase?
    • Any help is appreciated!
  • Generate a crypto token based on HW in LanScan Pro
  • Upgrade LanScan to 6.0 with new menu
  • LanScan Pro user will download LanScan 6.0 on the same machine
  • Insert crypto token on the same machine in LanScan
  • If success, display a purchase of a free In-App, similar to the paying In-App
  • Users will be able to restore the free In-App purchase on other devices normally

Any advice / suggestion is appreciated! On Twitter, by email or by commenting this issue on GitHub.
