【NeonCalculator】 is a four-in-one calculator that handles everyday math, scientific functions, unit conversion, and currency conversion in one place, so calculating and converting happen without switching apps. Standard & Scientific Move freely between a clean standard keypad and scientific functions such as trigonometry, logarithms, powers, and constants for both quick sums and more advanced work. Unit Conversion Convert length, weight, area, volume, and temperature with results that update as you type, and swap the source and target units with a single tap. Currency Conversion Work with major world currencies, refresh reference rates automatically when online, and get an instant converted amount as soon as you enter a value. Calculation History Every result is saved in order, and tapping any entry brings it back so you can continue without retyping.

Verdict
The clearest difference is ads: Calculator . at none against Wallpapers's shown. Wallpapers's advantage is update cadence (every 3 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
