Verdict

The call

The clearest difference is rating: Chilipad at 4.7 against Sunlighten's 2.8. Chilipad also leads on ratings volume (5K vs 77) and update cadence (every 2 months vs every 4 months). Sunlighten's advantage is monetization model (free vs ad-supported) and device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
