Verdict

The call

The clearest difference is ads: Radar Flow at none against Altimeter's shown. Radar Flow also leads on update cadence (weekly vs every 6 months) and rating (5.0 vs 4.6). Altimeter's advantage is ratings volume (1.3K vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
