Time Warp Scan Cam&Face Filter is an Android utility app from HDY Apps that mixes an auto-scan filter with standard face effects. Basically, the main gimmick is a moving scan line that freezes part of your photo or video in time, creating a warped or rippled look. A lot of people first find these scan filters on TikTok and want to try them directly. Once you download it from Google Play and launch the app, the first impression is pretty straightforward—a bright camera view with the scan option right there. The app's install count is modest but decent, and it stays free to download. There's no forced login, which is nice. I noticed some banner ads at the bottom during use, and there are optional extra filter packs that cost money, but nothing that blocks the core scanning feature.

After tapping into the main scanning mode, the interface is simple but a little rough around the edges. You select your filter or the time warp scan, then press record or photo capture. The onboarding just shows a quick preview of how the scan line moves. In everyday use, the most common step is holding your phone steady while the line slides across the frame. That part works okay if your lighting is decent. I had a few moments where the scan got confused when I moved too fast, but that feels more like a limitation of the tech than a bug. A practical tip is to use it on a plain wall background so the warp effect stands out more. The smoothing buttons and mirror effects are handy for portrait shots, though the interface labels are a bit small on my screen.

After a couple of weeks of testing, I think this app is worth keeping if you enjoy producing that trippy, morphing look for social media posts. People who just want a basic selfie cam might find it unnecessary and prefer a more polished app like YouCam Perfect or Snapchat. What sets Time Warp Scan apart is that it offers this specific scanning effect without needing to share to a platform like TikTok. The overall build feels like a functional tool rather than a polished product. I'd recommend it for casual creative experiments, but maybe uninstall it if the ads or the restricted free filter selection get annoying.

• 🔄 The core auto-scan freeze effect is what makes this app stand out from the standard filters in Snapchat or YouCam. You can slide the scan line vertically or horizontally, capturing a frozen slice of motion while the rest stays live, creating that blinking time-warp aesthetic without editing.
• 🎭 The face filter library includes classic augmentations like puppy ears, floral crowns, and color overlays. While these are common in similar apps, they are implemented responsively here and can be combined with the scan mode, which is not always possible in more rigid tools like B612.
• 🎥 Unlike most video-only scan apps, this one allows you to capture both photos and videos with the warp effect. This is a small but notable flexibility compared to the scan filters in TikTok that are tied to the recording phase only.
• 📲 The app has a built-in mirror flip and slow-mo preview for output files. This helps you check the warp quality before saving, saving time on retakes, which is a feature missing in many free face filter applications.

• 🕹️ The time warp scan is genuinely responsive and fun. I've tried similar effects on Snapchat, but the standalone control here (speed, direction, stop point) feels more customizable for creative projects.
• 🎨 The app does not require an account to export high-resolution images. Many similar apps like Retrica prompt you to sign up before saving, which is annoying. This one just saves directly to your gallery.
• 📸 The interface stays simple enough that you can start scanning within ten seconds of opening it. Compared to YouCam Perfect's multi-tab layout, this is a no-nonsense tool for a specific style.
• 🖼️ The app handles a wide range of skin tones and lighting conditions well during the scan capture, which is a plus compared to scan effects in some region-locked apps that assume bright studio light.

• 📈 The app has a somewhat low install base and the developer HDY Apps does not push frequent updates. This makes me worry about long-term compatibility with newer Android versions, unlike the regular updates of bigger apps like B612.
• 📺 The banner ads at the bottom of the screen are persistent even during capture. This can be distracting, especially compared to the more integrated ad placement in something like YouCam Snap, which only shows ads between uses.
• 🔧 The face tracking occasionally lags on slower phones, particularly when using both the scan and a face filter simultaneously. The same dual-filters work smoother on Snapchat with optimized hardware support.
• 🚫 There is no undo or redo option for the scanning line if you accidentally trigger it in the wrong spot. You have to start the whole capture over, which is a small but consistent annoyance missing from competitor apps.
