Verdict

The call

The clearest difference is update cadence: ConvertCalc at every 8 days against Wallpaper Maker's every 3 months. ConvertCalc also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 77%). Wallpaper Maker's advantage is ratings volume (127 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Wallpaper Maker sells 3 in-app purchases, starting at $0.99 per month and ConvertCalc sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
