Savvy Shield vs cool

Savvy Shield shows you where your iPhone's data actually goes, then stops it. Every day, your apps quietly connect to trackers, ad networks, and data brokers in the background. Savvy Shield turns that hidden activity into a clear, plain-English view, so you can see which companies your phone is talking to and take back control. WHAT SAVVY SHIELD DOES • Reveals the trackers and destinations your device contacts • Blocks known trackers and ad networks before they load • Explains, in plain English, what each company takes and what its terms allow • Gives you a privacy score based on real evidence from your device • Shows you exactly what was blocked, so you can check the number yourself HOW IT WORKS On iPhone and iPad, Savvy Shield installs a small on-device VPN configuration built on Apple's Network Extension framework. It carries only your device's DNS lookups, the name-to-address requests, to Savvy's encrypted resolver. It does not route your web traffic through Savvy's servers, and it is not a general-purpose VPN. Because it uses Apple's VPN framework, iOS shows a VPN icon in the status bar while it is on. You allow it with one tap and can turn it off anytime in the app. Savvy Shield never reads the content of your messages or browsing. When a tracker is blocked, no connection is opened and nothing is uploaded. Some ads are not affected. Services that deliver ads from the same place as their own content, like video and social feeds, will still show them. We would rather tell you that than promise otherwise. BUILT BY A PRIVACY COMPANY We don't sell your data. We don't run ads. No hidden tracking. No account or sign-in is needed. SAVVY SHIELD SUBSCRIPTION • Savvy Shield Monthly, $4.99 per month, auto-renewable • Savvy Shield Yearly, $49.99 per year, auto-renewable • Prices shown in US dollars; your App Store storefront sets the local price • Payment is charged to your Apple ID at confirmation of purchase • Your subscription renews automatically unless canceled at least 24 hours before the end of the current period • Manage or cancel anytime in your App Store account settings Terms of Use (EULA): https://savvysignals.com/terms Privacy Policy: https://savvysignals.com/privacy

cool-radar turns the radios already inside your iPhone into a radar for the devices around you — with no extra hardware, and without inventing a single number. WHAT YOU SEE Nearby Bluetooth LE devices appear as contacts with an estimated distance, a bearing once there is enough geometry to support one, and a ranked guess at what each device actually is. The Wi-Fi card shows the link your phone is really on: type, interface, local address and subnet, the default gateway and the gateway's manufacturer. Where both ends have UWB hardware, distance stops being an estimate and becomes a measurement. HONEST BY DESIGN Every value carries a badge. "Measured" is a hardware reading. "Inferred" is a value the math derived. Distances read "≈ 4.5 m" because radio ranging is an estimate, not a ruler. When there is not enough geometry for a direction, the app draws a ring of possible positions and a question mark instead of a convincing-looking arrow. And when iOS simply does not expose something — neighbouring Wi-Fi networks, raw spectrum, Wi-Fi CSI — the app says so instead of filling the gap with fiction. THE MATH INSIDE • Log-distance path-loss inversion, with a per-device exponent that recalibrates itself from the geometry you walk • Kalman filtering with motion-gated noise, so a device that is standing still stops drifting on screen • Robust multilateration with Huber weights, so a single reflection off a wall cannot drag a position across the room • A naive-Bayes hypothesis engine that ranks device types from the broadcast name, company ID, advertised GATT services, transmit power, address policy and advertising cadence — and shows you the evidence behind every guess • Behaviour analytics over the signal time series: advertising interval, jitter, trend and periodicity • Radio tomography that maps excess path loss into an attenuation picture of the space FEATURES • Top-down radar with range rings, pinch to zoom, double tap to reset • Device list with search and type filters • Device card with signal history, ranked hypotheses and the evidence for each • Unwanted-tracker heuristics based on public advertising patterns • CSV export of a session • Full Russian and English, switchable inside the app PRIVACY All sensing and all math run on your iPhone. No account, no analytics, no tracking, no advertising identifier. One optional setting — off until you turn it on — may send a 24-bit manufacturer prefix to a public vendor database to name your router. Nothing else ever leaves the device. Use cool-radar only on networks and devices you are entitled to inspect. It does not decrypt Find My identities, does not enumerate neighbouring Wi-Fi networks, and provides no covert tracking of people. REQUIREMENTS iOS 18 or later. Bluetooth works on every iPhone. UWB distance needs U1/U2 hardware on both devices. Room geometry needs a LiDAR model. Anything unavailable on your hardware is shown as unavailable rather than simulated.
