# 心灯 vs Memos Mobile

The clearest difference is in-app purchases: 心灯 at none against Memos Mobile's 1. 心灯 also leads on ads (none vs shown) and iOS requirement (15.0 vs 18.0). Memos Mobile's advantage is update cadence (every 4 days vs every 3 weeks). On price and device support there is nothing between them.

Both are free to download. Memos Mobile sells 1 one-off in-app purchase. 心灯 asks for nothing beyond the download.
