# Solid Diary vs Call Scheduler

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.

Both are free to download. Solid Diary sells 2 one-off in-app purchases and Call Scheduler sells 1 in-app purchase, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Solid Diary against 5.0 for Call Scheduler. That said, the two scores are not equally well evidenced: Solid Diary has 26 ratings behind it against 1, so its average is the more settled of the two.

Solid Diary ships an update every 2 months, Call Scheduler every 8 days. The most recent releases landed on October 19, 2026 and October 13, 2026 respectively.
