# SMART vs NRL互联

The clearest difference is update cadence: NRL互联 at every 2 months against SMART's every 5 months. SMART's advantage is iOS requirement (9.0 vs 17.0). On price, ads, 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.

SMART ships an update every 5 months, NRL互联 every 2 months. The most recent releases landed on October 26, 2026 and October 28, 2026 respectively.
