Verdict

The call

The clearest difference is ads: Solid Diary at none against Call Scheduler's shown. Solid Diary also leads on ratings volume (26 vs 1). Call Scheduler's advantage is update cadence (every 8 days vs every 2 months) and monetization model (free with in-app purchases vs paid). On price, rating, in-app purchases and device support there is nothing between them.
