Verdict
The clearest difference is in-app purchases: Lockeigo at none against Stardust 英会話's 1. Lockeigo also leads on update cadence (every 2 days vs weekly). Stardust 英会話's advantage is ads (none vs shown). On price, review sentiment, monetization model and device support there is nothing between them.
