Verdict

The call

The clearest difference is review sentiment: G at 80% against iCelsius's 36%. G also leads on rating (4.7 vs 4.2) and update cadence (fortnightly vs every 2 months). iCelsius's advantage is in-app purchases (none vs 4). On price, ads, monetization model and device support there is nothing between them.
