Verdict

The call

The clearest difference is ads: Tendrite at none against Umi's shown. Tendrite also leads on rating (5.0 vs 4.8). Umi's advantage is ratings volume (2.7K vs 1) and chart position (#173 vs unranked). On price, update cadence, in-app purchases and monetization model there is nothing between them.
