Verdict

The call

The clearest difference is monetization model: Bumper.io at free with in-app purchases against String.io's subscription. Bumper.io also leads on ratings volume (196K vs 1.8K) and update cadence (every 3 weeks vs every 3 months). String.io's advantage is review sentiment (58% vs 38%). On price, rating, ads and in-app purchases there is nothing between them.
