Verdict
The clearest difference is in-app purchases: PolyU Library at none against PTE Alpaca's 7. PolyU Library also leads on ads (none vs shown). PTE Alpaca's advantage is update cadence (every 3 weeks vs every 4 months). On price, device support and iOS requirement there is nothing between them.
