What’s new

Version 1.11 · Updated October 21, 2026

WLAN Optimizer 1.11 – our biggest update yet Walk through your home once – and your measurement points become a floor plan of your entire floor. With walls, doors and a coverage area that shows how well your Wi-Fi reaches every room. So you see not only where it's weak, but also why. GPS measurements in gardens and parks are now shown on the map with pinpoint accuracy. 1. AREAS INSTEAD OF DOTS As you scan, a continuous area grows with every step. In the results, it's colored by signal quality. On devices with LiDAR, the color stops at the wall instead of bleeding into the next room. 2. A FLOOR PLAN FROM YOUR WALK Walls appear above the area – even without LiDAR. Solid means measured, dotted means inferred, dashed means derived. Gaps stay gaps: that's where your doors are. 3. TRANSPARENT DOWN TO THE DETAIL The map shows you what it's based on: "with depth data" or "from your walking path", plus the quality of the floor plan. So you can put every result in context. Tip: A thorough walk gives you the most accurate floor plan. 4. OUTDOORS ON A REAL MAP Garden, patio, yard: your path is recorded on the Apple map, and every measurement point sits at its real position. Your path and measurement points now also appear on the map in the results. ALSO NEW - Four map layers you can toggle on and off - Full-screen view - Floors right on the home screen - Area and floor plan in the report - Guidance on holding your device correctly before scanning - Alert when your iCloud storage is full - More robust scanning - Fixed: On weak Wi-Fi, your iPhone silently switched to cellular data – making a dead spot look healthy.
