# 挖煤姬 vs IA ONE

The clearest difference is rating: 挖煤姬 at 4.9 against IA ONE's 1.0. 挖煤姬 also leads on ratings volume (614 vs 1) and device support (3 vs 1). IA ONE's advantage is ads (none vs shown) and chart position (#16 vs unranked). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 挖煤姬 sells 5 one-off in-app purchases and IA ONE sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
