# 个税 vs SeeChanges AI

The clearest difference is in-app purchases: 个税 at none against SeeChanges AI's 10. SeeChanges AI's advantage is ads (none vs shown) and update cadence (every 2 days vs every 2 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. SeeChanges AI sells 10 in-app purchases, starting at $3.99 per 3 months. 个税 asks for nothing beyond the download.

个税 ships an update every 2 weeks, SeeChanges AI every 2 days. The most recent releases landed on October 7, 2026 and October 16, 2026 respectively.
