Leave a spare iPhone or iPad at home and come back to see what happened. On-device AI saves short clips only when your dog, cat, a person, or a chosen object appears. No account, no cloud: clips stay in local Files storage on your device. Live viewing is local only. Peer Camera works between two nearby iPhones or iPads on the same Wi-Fi network. Try it free for 5 minutes a day, or unlock unlimited viewing with Premium. It does not work remotely over the internet. RECORD ONLY WHAT MATTERS • See when your dog, cat, or another pet returns to view • Watch a doorway, room, desk, backpack, or important object • Capture short clips during training, experiments, or everyday routines • Use movement detection when activity matters more than a specific object • Turn a spare iPhone or iPad into a private local camera OBJECT OR MOVEMENT DETECTION Use on-device object detection for supported targets such as people, dogs, cats, birds, backpacks, and balls. Choose movement mode when any meaningful activity should start recording. Clear sensitivity presets help balance quick reactions against small background movements. KEEP RELATED MOMENTS TOGETHER If a target leaves and returns, Detective Cam can keep confirmed events in the same pending session. Continue watching, then save the related moments as one clip when you are ready. PRIVATE BY DESIGN Detection runs on your device. Clips stay in local Files storage, no account is required, and you decide when watching starts, a session is saved, or a clip is deleted. CAMERA AND TRACKING CONTROLS • Optional detection boxes show what the app is following • Simple presets plus fine-tuned sensitivity controls • Camera zoom and Motion Zoom Assist on supported devices • Tracking profiles for battery life or higher accuracy • Siri and App Shortcuts for common recorder actions LIVE VIEWING ON YOUR WI-FI Live viewing needs both devices on the same Wi-Fi network. Try it free for 5 minutes a day, or get unlimited viewing with Premium. Use one nearby iPhone or iPad as the camera and watch from another nearby iPhone or iPad. It works only between devices on that network, not over the internet. The connection is encrypted and protected by a pairing code. FREE AND PREMIUM The free plan includes recording for every built-in target and movement, camera controls, Shortcuts, and a daily allowance of saved sessions. Detective Cam Premium adds unlimited saves and events, more clip history, custom target phrases, High Accuracy tracking, and unlimited Peer Camera. Monthly and lifetime purchase options are available. Detective Cam is designed for focused local recording and review. Detection can miss or misidentify objects. It is not a professional alarm system, emergency monitor, or replacement for dedicated safety equipment.

CountLens
Read full descriptionHide full description
CountLens counts whatever shows up more than once in a photo. You mark one example, the app takes care of the rest. Here is how it works: take a picture or pick one from your library, draw a frame around one object, done. CountLens scans the whole photo and marks every find. Each match comes with a score, so you can tell right away how solid the count is. Shaky matches? Filter them out with a slider. WHAT IT DOES • Counts screws, SMD parts, labels, packages and much more • You mark one example, CountLens finds all the others • Every match gets a score, and you decide where the cutoff is • Can also find rotated objects and slightly different sizes • Full screen view with zoom to check every single match BUILT FOR EVERYDAY WORK Incoming goods, quality checks, production: counting parts on a PCB, checking pieces in a tray, making sure a kit is complete. Wherever counting by hand takes forever and mistakes creep in, a photo is faster. YOUR PHOTOS STAY YOURS Everything runs right on your device. No cloud, no account, no ads, no tracking. Your photos never leave your phone.

Verdict
The clearest difference is in-app purchases: CountLens at none against Detective Cam's 2. CountLens also leads on iOS requirement (13.0 vs 17.0). On price, ads and device support there is nothing between them.
