Verdict

The call

The clearest difference is review sentiment: Optimal State at 100% against PESI's 14%. Optimal State also leads on rating (5.0 vs 4.7). PESI's advantage is update cadence (fortnightly vs every 5 months) and ratings volume (3.5K vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PESI sells 7 one-off in-app purchases and Optimal State sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Optimal State holds the better App Store score, 5.0 against 4.7.
