# Comet vs MemoMind

The clearest difference is review sentiment: MemoMind at 100% against Comet's 65%. MemoMind also leads on rating (5.0 vs 4.8) and iOS requirement (15.6 vs 18.0). Comet's advantage is ratings volume (7.8K vs 4) and update cadence (weekly vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Comet sells 3 in-app purchases, starting at $20.00 per month and MemoMind sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

MemoMind holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Comet has 7.8K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 65% of Comet's written reviews are positive against 100% of MemoMind's.

Comet ships an update weekly, MemoMind every 2 weeks. The most recent releases landed on October 16, 2026 and October 10, 2026 respectively.
