Verdict

The call

The clearest difference is rating: Calculator Widget Pro at 4.5 against Alti's 3.9. Calculator Widget Pro also leads on review sentiment (67% vs 32%) and update cadence (every 2 days vs every 37 months). Alti's advantage is ratings volume (271 vs 11) and iOS requirement (12.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
