Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
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.
MemoLib ships an update every 3 days, Thea monthly. The most recent releases landed on October 13, 2026 and October 17, 2026 respectively.
