Verdict
The clearest difference is price: Koine Companion at Free against AWS Machine Learning Prep PRO's $2.99. Koine Companion also leads on update cadence (every 5 days vs every 55 months). AWS Machine Learning Prep PRO's advantage is in-app purchases (none vs 1). On ads, device support and iOS requirement there is nothing between them.
