Undetectag, track stolen items with AirTag
I developed a device that turns an Airtag on and off at specific intervals. Current Airtags are detectable right away and cannot be used to track stolen property. That device allows you to hide an Airtag in your car, for example, and someone that steals your car will not be able to use some app to detect it. The Airtag will also not warn the thief of its presence. After some hours, the Airtag turns on again and you can find out its location. It’s not foolproof, as the timing has to be right, but still useful. What do you think?

In plain words
Undetectag is a device that controls when an AirTag broadcasts its signal by turning it on and off at set intervals. Designed for vehicle owners concerned about theft, it allows users to hide an AirTag in a car without it being immediately detectable by would-be thieves. The device delays activation so the thief won't receive warnings about the tracker's presence, then reactivates periodically to let owners locate their vehicle. The creator acknowledges the method isn't completely foolproof but offers a practical option for tracking stolen property.

Current AirTags are detectable right away and cannot be used to track stolen property. This add-on device turns an AirTag on and off at specific intervals. With it you can hide an AirTag in your car, for example, and it will be way less likely that a thief stealing your car notices it with an app. The AirTag will also not warn the thief of its presence when turned off. After some hours, the AirTag will turn on again so that you can find out its location. What do you think?

Tapflow 2.0▲1,125We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
