Public and shared spaces are a part of everyday life — from coffee shops and libraries to coworking hubs and waiting rooms. But these environments often come with a lack of visibility into what’s connected around you. This app helps restore that clarity by giving you tools to quickly scan for nearby wireless activity and stay informed in real time. Start with a Wi-Fi or Bluetooth scan to instantly identify devices connected near your location. Whether it’s a forgotten speaker, a paired keyboard, or something unfamiliar, you’ll get clear results without technical hassle. In places where others are constantly coming and going, this simple check can make a big difference in maintaining your privacy. Infrared scanning gives you an added layer of protection. Using your phone’s camera with a red filter effect, you can visually detect bright light sources that might signal obscured electronics or active transmitters. This function is silent, fast, and doesn’t require any extra hardware. All scan results are saved automatically. The app organizes your history for easy access, helping you track changes across visits or revisit areas you’ve already checked. The interface is streamlined — switch between modes instantly, access basic guidance when needed, and keep your digital awareness sharp without complexity. Free features: • Device history and saved results • Clean and simple interface Pro features (available via subscription): • Basic Wi-Fi and Bluetooth scanning • Unlimited scans with no wait time • IP tracking with real-time monitoring • Ad-free experience • Early access to new tools Pro Subscription Plans: • Weekly Plan • Monthly Plan Each subscription includes a 3-day free trial.

Verdict
The clearest difference is ads: Sysly at none against Spyf's shown. Sysly also leads on update cadence (monthly vs every 5 months). Spyf's advantage is iOS requirement (16.0 vs 26.5). On price, in-app purchases and device support there is nothing between them.
