Verdict
The clearest difference is update cadence: Hopium at every 10 days against SpeakLine's every 3 months. Hopium also leads on iOS requirement (15.6 vs 17.2). SpeakLine's advantage is monetization model (free vs free with in-app purchases) and rating (4.4 vs 4.1). On price, review sentiment, ads and in-app purchases there is nothing between them.
