Verdict
The clearest difference is rating: Solid Diary at 5.0 against PulseCalendar's 4.0. Solid Diary also leads on review sentiment (86% vs 75%) and ratings volume (26 vs 7). PulseCalendar's advantage is update cadence (every 3 days vs every 2 months) and monetization model (freemium vs paid). On price, ads, in-app purchases and device support there is nothing between them.
