Verdict
The clearest difference is price: WLCApp at Free against Harmonizr's $4.99. WLCApp also leads on rating (5.0 vs 4.2) and update cadence (weekly vs every 4 months). Harmonizr's advantage is in-app purchases (none vs 1) and ratings volume (27 vs 3). On ads and device support there is nothing between them.
