Verdict

The call

The clearest difference is monetization model: Private Diary at free against Lunarwrite's free with in-app purchases. Private Diary also leads on review sentiment (100% vs 85%) and rating (5.0 vs 4.8). Lunarwrite's advantage is ratings volume (100 vs 2). On price, ads, in-app purchases and device support there is nothing between them.
