Verdict

The call

The clearest difference is rating: Telemetry Camera at 4.6 against OverlayGPS's 4.0. Telemetry Camera also leads on update cadence (weekly vs fortnightly) and ratings volume (34 vs 5). OverlayGPS's advantage is review sentiment (60% vs 43%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Telemetry Camera holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Telemetry Camera has 34 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 43% of Telemetry Camera's written reviews are positive against 60% of OverlayGPS's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Telemetry Camera ships an update weekly, OverlayGPS fortnightly. The most recent releases landed on September 28, 2026 and October 7, 2026 respectively.
