Verdict

The clearest difference is in-app purchases: SmarTrial at none against Periodontal Chart's 2. SmarTrial also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.1). Periodontal Chart's advantage is update cadence (weekly vs every 3 weeks) and device support (4 vs 2). On price there is nothing between them.
