# SuppaLog vs StackDay

The clearest difference is ads: SuppaLog at none against StackDay's shown. SuppaLog also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). StackDay's advantage is update cadence (every 3 days vs every 2 weeks) and ratings volume (5 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. SuppaLog sells 2 in-app purchases, starting at $4.99 per month and StackDay sells 8 in-app purchases, starting at $0.99 per 7 days. 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 SuppaLog against 5.0 for StackDay. That said, the two scores are not equally well evidenced: StackDay has 5 ratings behind it against 1, so its average is the more settled of the two.

SuppaLog ships an update every 2 weeks, StackDay every 3 days. The most recent releases landed on September 25, 2026 and September 28, 2026 respectively.
