Verdict

The call

The clearest difference is in-app purchases: Stereo at none against Postra's 6. Stereo also leads on ratings volume (10K vs 2). Postra's advantage is rating (5.0 vs 4.6) and update cadence (every 5 days vs every 11 days). On price, ads, device support and iOS requirement there is nothing between them.
