# 軽減税率 vs PSRIO

The clearest difference is in-app purchases: 軽減税率 at none against PSRIO's 1. 軽減税率 also leads on device support (3 vs 1) and iOS requirement (13.0 vs 18.0). PSRIO's advantage is ads (none vs shown) and update cadence (every 3 days vs every 8 months). On price there is nothing between them.

Both are free to download. PSRIO sells 1 in-app purchase, starting at $2.99 per month. 軽減税率 asks for nothing beyond the download.

軽減税率 ships an update every 8 months, PSRIO every 3 days. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
