# 폴라리스 vs Brain Dump

The clearest difference is ads: Brain Dump at none against 폴라리스's shown. 폴라리스's advantage is update cadence (every 6 days vs fortnightly) and iOS requirement (15.1 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

폴라리스 ships an update every 6 days, Brain Dump fortnightly. The most recent releases landed on October 31, 2026 and October 29, 2026 respectively.
