Verdict

The call

The clearest difference is in-app purchases: HUMBLE at none against Sign.Plus's 4. HUMBLE also leads on rating (5.0 vs 4.8). Sign.Plus's advantage is ratings volume (292 vs 1) and update cadence (every 3 weeks vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
