Verdict
The clearest difference is in-app purchases: RST 599 at none against Partial Translation Learning's 1. RST 599 also leads on iOS requirement (13.0 vs 16.0). Partial Translation Learning's advantage is ads (none vs shown) and update cadence (every 2 days vs every 2 months). On price and device support there is nothing between them.
