# IMT vs SAMF

The clearest difference is review sentiment: IMT at 100% against SAMF's 13%. IMT also leads on monetization model (free vs subscription). SAMF's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. IMT sells 3 one-off in-app purchases and SAMF sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

IMT ships an update every 4 months, SAMF every 3 months. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
