# ZIGCAM vs TDLiDAR

The clearest difference is rating: ZIGCAM at 5.0 against TDLiDAR's 4.3. ZIGCAM also leads on iOS requirement (14.1 vs 18.6). TDLiDAR's advantage is review sentiment (85% vs 50%) and update cadence (every 5 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ZIGCAM sells 1 one-off in-app purchase and TDLiDAR sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ZIGCAM holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: TDLiDAR has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of ZIGCAM's written reviews are positive against 85% of TDLiDAR's, so the app with the better star average is not the one people write more warmly about.

ZIGCAM ships an update fortnightly, TDLiDAR every 5 days. The most recent releases landed on September 21, 2026 and September 23, 2026 respectively.
