# OTP Auth vs 小药经·智策

The clearest difference is in-app purchases: 小药经·智策 at none against OTP Auth's 1. 小药经·智策 also leads on update cadence (every 2 months vs every 6 months). OTP Auth's advantage is device support (4 vs 2). On price, ads and iOS requirement there is nothing between them.

Both are free to download. OTP Auth sells 1 one-off in-app purchase. 小药经·智策 asks for nothing beyond the download.

OTP Auth ships an update every 6 months, 小药经·智策 every 2 months. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
