The clearest difference is rating: FotoTrans at 4.2 against 极空BMS's 3.5. FotoTrans also leads on device support (3 vs 1) and iOS requirement (8.0 vs 17). 极空BMS's advantage is review sentiment (35% vs 0%) and update cadence (every 3 weeks vs every 17 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

FotoTrans holds the better App Store score, 4.2 against 3.5. Both are backed by a comparable volume of ratings — 10 and 37 respectively.
