About

Triangle Help

This utility app calculates missing sides and angles of a triangle given at least three known measures. It displays the formulas used for learning and supports angle input in degrees or radians, with adjustable decimal precision.

Highlights
  • Solves for missing triangle sides and angles
  • Displays formulas used for learning
  • Accepts angles in degrees or radians
  • Adjustable decimal precision
  • Large text display

Triangle Solver! FEATURES INCLUDE - Presents the formulae it uses - Accepts angles in degrees OR radians - Reports answers to many decimal places - BIG TEXT To toggle between degrees and radians simply tap the blue angle unit symbol. Given three measures of sides or angles of a triangle (including at least one side) this app can find and report the rest. This app "solves" triangles. This app's most special feature is that it reports the formulae it uses so you can learn how to solve triangles yourself. The number of decimal places is determined by the width of your screen. If it's too few, turn your device horizontal! Each side is across from the angle of the same letter. Sides are lowercase, angles are uppercase and denoted with the angle symbol (∠). This app may be good for engineers or Trigonometry students.

About

Capacitor Calculator

This utility app calculates the time constant and energy stored in a capacitor. It helps understand the time-delay characteristics of electrical circuits when a voltage is applied.

Highlights
  • Calculate time constant (RC)
  • Calculate energy stored (E)
  • Input voltage, capacitance, and resistance
  • Understand capacitor charging/discharging
  • Analyze circuit time-delay

Capacitor Calculator is an all-in-one toolkit for students, hobbyists, technicians, and electrical engineers who work with capacitors every day. Whether you are designing an RC circuit, sizing a power supply, building a flash circuit, or studying electromagnetism for an exam, this app gives you fast and accurate answers together with the formulas and calculation steps behind every result. THREE CALCULATORS IN ONE APP 1. Capacitor Charge and Time Constant Enter supply voltage (V), capacitance (C), and series resistance (R) to instantly calculate: • Stored energy: E = 0.5 * C * V^2 • RC time constant: T = R * C • Charge stored: Q = C * V 2. Parallel Plate Capacitance Compute capacitance using plate area, separation distance, and relative permittivity with: C = e0 * er * A / d Perfect for understanding how geometry and dielectric materials affect capacitance. 3. Spherical Capacitor Calculate capacitance between two concentric conducting spheres using: C = 4 * pi * e0 * er * R1 * R2 / (R2 - R1) Choose from built-in dielectric materials including vacuum, air, paper, glass, mica, ceramic, polyethylene, polystyrene, Teflon, silicon, and water. BUILT FOR REAL WORK • Unit-aware inputs for voltage, capacitance, resistance, length, and area • Scientific notation for very small or very large values • Full calculation steps with formulas and substituted values • Copy results with one tap • Save and review calculation history • Everything runs on-device with no tracking, no account, and no internet required A POLISHED NATIVE IOS EXPERIENCE • Full Light Mode and Dark Mode support • Reference tab with physical constants, formulas, and dielectric materials table Capacitor Calculator is a focused tool for electrical engineering, electronics design, physics homework, and EE coursework. Download it once and keep professional-grade capacitor calculations in your pocket. Thanks for your support, and visit nitrio.com for more apps for your iPhone and iPad.

Verdict

The call

The clearest difference is price: Triangle Help at Free against Capacitor Calculator's $2.99. Triangle Help also leads on rating (5.0 vs 3.8) and iOS requirement (9.3 vs 17.6). Capacitor Calculator's advantage is ratings volume (4 vs 1). On ads, in-app purchases and device support there is nothing between them.
