• WiFi Analyzer: Scan nearby networks, analyse signal strength, and browse channels across 2.4 GHz, 5 GHz, and 6 GHz bands. Find the quietest channel for your router.
• Speed Test: Measure your real download speed, upload speed, ping, and jitter. Track results over time to spot trends.
• Ping: Test reachability and latency with ICMP, TCP, or HTTP ping. View min/max/average stats and packet loss.

Entering a promo code outside a sale used to replace the Lifetime price with a "promotional" one at the same money, struck through against itself, under a countdown to an offer that was not running.

The discounted row and the countdown now show up only when the store is really quoting Lifetime below full price. The rest of the time you see the price you can actually pay.
