Verdict
The clearest difference is in-app purchases: HapiEnglish at none against Language Byte's 2. HapiEnglish also leads on iOS requirement (13.0 vs 17.4). Language Byte's advantage is update cadence (every 4 months vs every 24 months). On price, ads and device support there is nothing between them.
