Verdict
The clearest difference is ads: Inkline at none against 100 Year Diary Journal's shown. Inkline also leads on device support (3 vs 1). 100 Year Diary Journal's advantage is update cadence (every 3 days vs monthly). On price, in-app purchases and iOS requirement there is nothing between them.
