Verdict
The clearest difference is update cadence: Slate at every 3 days against Diddit's monthly. Diddit's advantage is ratings volume (6 vs 1) and iOS requirement (18.0 vs 26.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Diddit sells 2 in-app purchases, starting at $1.99 per month and Slate sells 2 in-app purchases, starting at $2.99 per month. 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 Diddit against 5.0 for Slate. That said, the two scores are not equally well evidenced: Diddit has 6 ratings behind it against 1, so its average is the more settled of the two.
Diddit ships an update monthly, Slate every 3 days. Both last shipped on October 31, 2026.
