Verdict

The call

The clearest difference is update cadence: Bubblegum at every 2 days against Flipside's fortnightly. Bubblegum also leads on ratings volume (175 vs 6) and monetization model (freemium vs paid). Flipside's advantage is review sentiment (100% vs 80%). On price, rating, ads and in-app purchases there is nothing between them.
