Smart Remote . vs EchoMap

【Smart Remote】 turns your iPhone into a smart TV remote that works over your home Wi-Fi, putting every button you need on screen with no extra hardware. **Smart TV Remote** Control your TV with a familiar direction pad or a swipe-friendly touchpad, then adjust power, volume, mute, channels and playback without juggling multiple remotes. **Auto Discovery & Pairing** Scan the same Wi-Fi network to find Roku, Fire TV, LG, Samsung, Sony, Vizio and Android TV, or connect manually by IP address. PIN pairing keeps the link secure, and Wake-on-LAN can wake a TV from standby. **Streaming & Text Input** Open Netflix, YouTube, Prime Video and more directly on the big screen, switch HDMI or AV sources, and type search words with the on-screen keyboard instead of tapping letter by letter. **Siri Shortcuts** Add remote actions to the Shortcuts app and control the TV hands-free — say "Hey Siri, pause the TV," or run one-tap Movie Mode to power on, switch input and launch your streaming app. Premium Account Pricing and Terms $0.99/week* $39.99/year* *Prices are shown in US dollars; actual charges may be converted to your local currency based on your country/region.

EchoMap is a visual sound exploration app where users scan virtual spaces with echo pulses. Send signals, watch reflections return, and uncover hidden walls, shapes, and distances through a clean sonar-style interface. The app turns echo timing and sound reflection into simple interactive experiments, helping users see how sound can be used to understand space.
