Who makes Findy, and why it is built this way
Findy is made by Flaps Apps, a small studio focused on honest privacy tools. It is deliberately smaller in what it claims than most apps in this category — because most of what those apps claim is not something a phone can do.
Who builds it
Findy is designed, written and maintained by Flaps Apps, a small studio focused on honest privacy tools. There is no elaborate company story to tell. When you email about a bug or a wrong result, you are writing to the small team that builds the app.
That is worth stating plainly because it sets your expectations correctly: replies may take a few days, and features arrive at the pace a small studio can build and test them.
The problem with this category
Search the App Store for hidden-camera detectors and you will find apps that claim to do things an iPhone physically cannot do. The recurring ones:
"RF signal detection"
An iPhone has no general-purpose radio-frequency receiver available to apps. It cannot sweep the spectrum for transmitters. An app showing an RF meter is usually showing you the magnetometer, or an animation.
"AI room scanning"
Pointing a camera at a wall and running a model over the image does not reveal an object hidden inside the wall. If it is not visible to the lens, no amount of processing recovers it.
"Pinpoint location"
No app locates a Bluetooth device from signal strength. Findy estimates a distance and shows a direction arrow, but both are derived from signal strength alone, using a generic model rather than a measurement — walls, bodies, orientation and transmit power distort them badly. They are a warmer/colder aid while you move, never the device's actual position, and we say so.
These claims are not harmless. They send people to bed believing a room has been cleared when it has not, and they send other people to confront a stranger over a reflection from a screw head.
What Findy does instead
The rule the app is built to is simple: ship only methods that do something real, and document where each one fails.
- Every feature maps to a physical property the phone can genuinely measure — a lens reflecting directed light, infrared reaching the camera sensor, a device advertising over Bluetooth, a host responding on the local network, a distortion in the magnetic field.
- Nothing is included because it looks impressive in a screenshot. If a method would only ever produce theatre, it does not ship.
- Results are labelled as observations — possible, unidentified, worth checking — never as verdicts.
- The guided visual checklist is treated as the most important feature, not a filler one. Your own eyes on the object remain the most reliable step in any inspection.
Evidence, not just claims
A claim is only worth anything if it can be checked. That is why the app is documented in the open, method by method, and evaluated against a published test plan.
How the app is funded
Findy is free to download, and the Bluetooth scanner, magnetic-field checks, background item-tracker detection and guided checklist are the free tier — no account, no sign-up, no time limit. These are not trial versions. The camera tools and the network scanner are part of an annual subscription, which is what pays for the development time. There are no ads, no analytics or tracking SDKs, and no account to create — scan results stay on your device. Subscription details are in the support centre, stated as the annual amount you are actually charged.
Get in touch
Corrections are genuinely welcome, especially about detection claims. If a limitation is described wrongly, or the app produced a result that does not match what was in the room, that is useful — send the device model, the iOS version and what you observed.
Subscriptions, billing and refunds are handled by Apple rather than by us; the subscriptions page explains the right route for those.
See the methods before you download
The technical documentation and the limitations are public, and worth reading first. The app is free to install once you have.
