Verdict

The call

The clearest difference is update cadence: MemoLib at every 3 days against Thea's monthly. Thea's advantage is rating (4.9 vs 4.5) and ratings volume (2.5K vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. MemoLib sells 31 in-app purchases, starting at $3.99 per month and Thea sells 2 in-app purchases, starting at $12.00 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Thea holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Thea has 2.5K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 75% of MemoLib's written reviews are positive against 93% of Thea's.

UpkeepUpdate frequency

MemoLib ships an update every 3 days, Thea monthly. The most recent releases landed on October 13, 2026 and October 17, 2026 respectively.
