"I think my iPhone might have been hacked." When that thought hits, it is hard to know what to look at. HACK CHECK walks through what your iPhone can actually tell you, one item at a time. β Honesty first This app will never tell you "you have been hacked," nor "you are safe." Neither can be determined from what iOS makes available to an app. Instead, it reports the current state of each item it was able to check - and it shows you, in plain sight, the list of things it cannot check at all. β Results stay on your device The items checked, the findings, and the values read are stored only on your iPhone. The developer cannot see them. You can delete your history at any time, or export it to a file. Whether that file goes anywhere is entirely your decision. β What is checked - Passcode and biometric settings - Signs that the device has been modified - Whether the connected Wi-Fi network is encrypted - Proxy and VPN configuration - Screen recording and mirroring status - Whether notification contents appear on the lock screen - Storage and memory headroom - Time since the last restart and more Choose from three levels of depth. The standard check takes about ten seconds; the most thorough takes about a minute. β What cannot be checked iOS strictly limits what one app can learn about other apps and about network traffic. That protects you - and it also means the following cannot be determined: - The list of installed apps - What data other apps actually collect - The contents of network traffic - Past sign-in history - The presence of malware - Call history - The contents of SMS and messages "Could not be checked" is not the same as "no problem found." The app keeps that distinction visible throughout. β Pricing Free, with no in-app purchases. Ads are shown, but they are non-personalized - your activity is not tracked. β Please note This app is not a substitute for a professional investigation. If you believe you have actually been targeted, please contact the police or a specialist.

Verdict
The clearest difference is ads: DocProtect at none against HackCheck's shown. DocProtect also leads on update cadence (daily vs every 2 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
