Bubble Level + Compass combines a bubble level and a compass, with advanced controls for users who want more than the basics. Use it to check horizontal/vertical/surface angles, or get compass direction relative to either true or magnetic north. For users who work with physical compasses, magnetic declination is also provided to convert magnetic readings to true north readings. The level includes gyroscope calibration, which is especially useful on phones with a raised camera bump or an uneven back/case. No nagging popups or interruptions. The free version only includes a small banner ad at the bottom. Features • Bullseye level plus horizontal and vertical levels with 0.1 degree precision. • Compass with true north and magnetic north. • Magnetic declination display for converting magnetic readings to true north readings. • Gyroscope calibration for phones that do not rest perfectly flat. • Gyro or accelerometer sensor mode. • Clean interface with no popup interruptions. If you enjoy the app, leaving a review would help. An ad-free Pro version is also available, with more features including Apple Watch support, night mode, slope/inclination %, and pitch, yaw, and roll rotation rate.

Verdict
The clearest difference is ads: Touch at none against Bubble Level + Compass's shown. Touch also leads on update cadence (fortnightly vs every 4 months) and monetization model (free vs free with in-app purchases). Bubble Level + Compass's advantage is ratings volume (34 vs 6) and iOS requirement (12.0 vs 16.6). On price, rating, in-app purchases and device support there is nothing between them.
