# iM.Master vs Flash Studio

The clearest difference is rating: Flash Studio at 4.8 against iM.Master's 2.8. Flash Studio also leads on update cadence (weekly vs every 2 months) and ratings volume (4.2K vs 90). iM.Master's advantage is ads (none vs shown) and monetization model (free vs ad-supported).
