# Lightspeed App vs TwoTenDegrees

The clearest difference is rating: TwoTenDegrees at 5.0 against Lightspeed App's 3.3. TwoTenDegrees also leads on update cadence (every 9 days vs every 6 months). Lightspeed App's advantage is ratings volume (49 vs 1) and review sentiment (12% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

TwoTenDegrees holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: Lightspeed App has 49 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 12% of Lightspeed App's written reviews are positive against 0% of TwoTenDegrees's, so the app with the better star average is not the one people write more warmly about.

Lightspeed App ships an update every 6 months, TwoTenDegrees every 9 days. The most recent releases landed on October 14, 2026 and September 27, 2026 respectively.
