Verdict
The clearest difference is update cadence: Laifen at every 3 weeks against HOTO's every 20 months. Laifen also leads on rating (2.4 vs 2.2) and ratings volume (79 vs 10). HOTO's advantage is iOS requirement (11.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
