Hidden Camera Detector - Peek

What it does

Peek is a mobile utility designed to enhance personal privacy and security. The app's primary function is to scan the user's current Wi-Fi network to discover all connected devices. It then presents a list of these devices, helping the user identify any potentially unauthorized or suspicious hardware, such as hidden spy cameras.

Where it shines

The app excels in its clear and direct value proposition. From the moment it opens, it establishes credibility with strong social proof, displaying a large user base and high average rating (00:04). The core scanning feature is straightforward; a large, central button initiates the process (00:58), which uses a clean, radar-like animation to provide visual feedback. The results screen (01:08) neatly categorizes devices, making it easy to see what's on your network.

UX highlights

Upfront Social Proof: The app immediately builds trust at 00:04 by highlighting its 3M+ users and 4.8-star rating before asking for any permissions.
Permission Priming: Instead of just showing system dialogs, the app uses clean, custom warm-up screens for location (00:07) and notifications (00:13) to explain why access is needed.
Clear Freemium Path: The main screen for free users features a prominent "SCAN (Watch Ad)" button (01:25), making the path to using the core feature clear and unambiguous.
Actionable Tips: Beyond the scanner, the app provides a helpful section with manual tips for finding hidden cameras (02:01), adding value even without a network scan.
Organized Results: Scan results at 01:08 are grouped into "Suspicious Devices" and "Secure Devices," which helps users quickly assess potential threats.

Monetization & growth

The app employs a hybrid monetization strategy. The initial onboarding flow funnels the user directly to a soft paywall at 00:19, offering weekly and yearly subscription plans. For users who skip the subscription, the app offers its core scanning feature for free in exchange for watching a rewarded video ad (01:30). Additionally, free usage is metered through a daily credit system, as seen in the settings at 02:39. This encourages habitual use while creating a clear incentive for power users to subscribe for unlimited, ad-free access.

Who it’s for

This app is for security-conscious individuals, particularly travelers staying in hotels or rentals, or anyone concerned about their privacy in unfamiliar spaces. It's also useful for homeowners or office managers who want to audit their network for unauthorized devices. The simple interface makes it accessible to non-technical users who need a quick way to check their surroundings for peace of mind.

Notes & opportunities

The user flow after a free scan could be clearer. After a scan completes at 01:08, tapping on any of the results (01:13) takes the user back to the paywall. While this is a valid upsell tactic, it could be frustrating. A better approach might be to show limited information about the device and then offer the full details as part of the premium subscription. This would demonstrate more value before hitting the paywall again.
