Calculator: Basic + Scientific

Hey everyone 👋 Just shipped my first-ever app — a calculator for Android with both basic and scientific modes (sin, cos, tan, √, log, ln, π, e, exponents). Built it as a university student (studying math/stats/econ) wanting something clean without the bloat most calculator apps have. Also added persistent history that survives closing the app — tap any past result to reuse it. Free, no ads, minimal permissions. Would love any feedback, especially on the UI or anything that feels missing — actively iterating on it.
