# Probability vs Lottery Stats

The clearest difference is review sentiment: Lottery Stats at 57% against Probability's 0%. Lottery Stats also leads on rating (4.5 vs 1.0) and ratings volume (61 vs 1). Probability's advantage is ads (none vs shown) and update cadence (every 10 days vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Probability sells 1 one-off in-app purchase and Lottery Stats sells 10 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Lottery Stats holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Lottery Stats has 61 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 0% of Probability's written reviews are positive against 57% of Lottery Stats's.

Probability ships an update every 10 days, Lottery Stats monthly. The most recent releases landed on October 5, 2026 and October 14, 2026 respectively.
