Verdict
The clearest difference is price: Protractor+ at Free against TiltMeter's $1.99. Protractor+ also leads on rating (4.1 vs 3.6) and ratings volume (10K vs 163). TiltMeter's advantage is review sentiment (58% vs 15%) and in-app purchases (none vs 1). On ads and device support there is nothing between them.

Protractor+ is free to download; TiltMeter costs $1.99 up front. Protractor+ sells 1 one-off in-app purchase. TiltMeter asks for nothing beyond the download.
Protractor+ holds the better App Store score, 4.1 against 3.6. That said, the two scores are not equally well evidenced: Protractor+ has 10K ratings behind it against 163, so its average is the more settled of the two. Written reviews complicate that: 58% of TiltMeter's written reviews are positive against 15% of Protractor+'s, so the app with the better star average is not the one people write more warmly about.
TiltMeter ships an update every 2 weeks, Protractor+ every 2 months. The most recent releases landed on November 10, 2026 and November 12, 2026 respectively.
