# StatsKey vs Inject

Inject's advantage is ratings volume (19 vs 4) and iOS requirement (16.0 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. StatsKey sells 6 in-app purchases, starting at $9.99 per month and Inject sells 11 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

StatsKey ships an update daily, Inject every 5 days. The most recent releases landed on September 30, 2026 and September 19, 2026 respectively.
