Verdict

The call

The clearest difference is in-app purchases: happram at none against Tone generator's 3. happram also leads on ads (none vs shown) and update cadence (every 10 days vs every 5 months). Tone generator's advantage is iOS requirement (12.0 vs 15.0). On device support there is nothing between them.
