Verdict

The call

The clearest difference is rating: Bubble Level® at 4.4 against Gyraline's 3.8. Bubble Level® also leads on monetization model (free with in-app purchases vs paid) and iOS requirement (11.0 vs 15.0). Gyraline's advantage is ads (none vs shown) and update cadence (fortnightly vs every 11 months). On price, ratings volume, in-app purchases and device support there is nothing between them.
