Verdict
The clearest difference is price: CaffLog at Free against Caffiend's $1.99. CaffLog also leads on update cadence (weekly vs monthly) and iOS requirement (15.0 vs 17.0). Caffiend's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
