# モチタン vs ディアトーク

The clearest difference is ads: ディアトーク at none against モチタン's shown. ディアトーク also leads on rating (5.0 vs 4.7). モチタン's advantage is ratings volume (143 vs 1) and update cadence (weekly vs every 3 weeks). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. モチタン sells 16 in-app purchases, starting at $9.99 per month and ディアトーク sells 2 in-app purchases, starting at $39.99 per month. Whichever you choose, the download price is not the number that matters.

ディアトーク holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: モチタン has 143 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 53% of モチタン's written reviews are positive against 36% of ディアトーク's, so the app with the better star average is not the one people write more warmly about.

モチタン ships an update weekly, ディアトーク every 3 weeks. The most recent releases landed on September 29, 2026 and September 28, 2026 respectively.
