Calculator for celestial navigation (CN). Supports just the basic add/subtract of degrees and minutes using the typical notation just in celestial navigation. Most calculators support degrees/minutes-as-fraction (26°23.5'). But they show results in degrees/minutes/seconds (26°23'30". For celestial navigation, sight reduction using HO249 tables and almanacs uses DD°MM.F'. This calculator is aimed specifically at that use case and thus only operates with DD°MM.F' and not with DD°MM'SS" While navigators should do this math by hand, using a calculator while practicing, learning or to double check is useful. This does just that, no more. ## Key features - Degrees and minutes addition/subtraction - DD°MM.F' notation support - Celestial navigation focus - Practice and double-checking tool - Simple, single-purpose design ## Recent user reviews (7 of 7) All indexed reviews: https://appshunter.io/ios/app/degree-calculator/id6450392179/reviews.md ### 5/5 — Perfect for celestial navigation *2026-03-26* Really well designed calculator that does one thing really well.
