Audio and podcasting decision
PodSpot
A single competent iOS developer can build and maintain a useful BLE‑based headphone finder; the product's value is implementation polish, App Store reach, and tuning from field data rather than hard technical moats.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All PodSpot alternatives, with the arithmetic →
What a replacement has to do
- Scan for nearby Bluetooth devices, select a target device, show a real‑time RSSI-based radar/strength meter to guide the user to the device, persist favorites and recent scans, and handle in‑app purchase unlock.
What it still won’t have
- App Store discoverability and existing user reviews
- Polish and UX refinements tuned by real user feedback
- Ongoing tweaks to signal-processing heuristics from field data
- Cross‑platform builds or integrations beyond iOS
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
PodSpot does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build an iOS SwiftUI app (iOS 13+) using Swift and CoreBluetooth that scans for nearby BLE devices, lists discovered devices, lets the user pick a target, and displays a real‑time RSSI-based proximity meter/radar. Use CoreData (or SQLite) for favorites/recent lists. Integrate StoreKit for a single in‑app purchase unlocking the radar. Include: smooth RSSI filtering, visual radar/strength indicator, background scan handling within iOS limits, simple settings and privacy notice, basic analytics (local events only), App Store packaging and an App Store receipt check. Out of scope: integrating with Apple's Find My network, cloud sync, or cross-platform clients. Provide error handling for Bluetooth denied/unavailable, unit tests for core RSSI logic, UI tests for main flows, and a CI workflow that builds and archives the app.
How we checked
How the score was reached
- Build verdict base78
- An open-source build was found+5
- 5 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score90
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
