# Mimir vs Synapse

The clearest difference is rating: Synapse at 5.0 against Mimir's 4.6. Synapse also leads on review sentiment (73% vs 60%) and iOS requirement (15.1 vs 26.1). Mimir's advantage is ratings volume (128 vs 5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Mimir sells 2 in-app purchases, starting at $12.99 per month and Synapse sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Synapse holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Mimir has 128 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 60% of Mimir's written reviews are positive against 73% of Synapse's.

Mimir ships an update every 10 days, Synapse every 2 weeks. The most recent releases landed on October 27, 2026 and October 28, 2026 respectively.
