Verdict

The call

The clearest difference is price: Bubble Level at Free against TiltMeter's $1.99. Bubble Level also leads on rating (4.5 vs 3.6) and update cadence (weekly vs every 2 weeks). TiltMeter's advantage is in-app purchases (none vs 11) and ads (none vs shown). On device support there is nothing between them.
