# Flashside vs Mopiq

The clearest difference is review sentiment: Flashside at 100% against Mopiq's 70%. Flashside also leads on rating (5.0 vs 4.7). Mopiq's advantage is ratings volume (1.4K vs 3) and iOS requirement (16.0 vs 18.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Flashside sells 2 in-app purchases, starting at $2.99 per month and Mopiq sells 9 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Flashside holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mopiq has 1.4K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of Flashside's written reviews are positive against 70% of Mopiq's.

Flashside ships an update fortnightly, Mopiq every 9 days. Both last shipped on November 13, 2026.
