Verdict
The clearest difference is in-app purchases: Chain at none against Bubble Level + Spirit Level's 7. Chain also leads on ads (none vs shown). Bubble Level + Spirit Level's advantage is update cadence (fortnightly vs every 2 months). On price, device support and iOS requirement there is nothing between them.
