ActionTree encompasses what we all need to function efficiently: Management of Projects and management of Time. Both entities are represented by separate but related views - the "Projects" view and the "Timeline" view. A tap on the view title switches between the two. The Projects view enables the user to create hierarchal projects. The Timeline view - a view of reminders and events sorted by time. In the Projects view, you can break your projects down to manageable steps that can be collapsed, expanded, fitted with quick reminders, photos and notes. The Timeline view provides list of reminders and events sorted by time. New reminders and events can be created and edited. Links are provided to correlate between the Projects and the Timeline views.

Advanced Calculator revolutionizes mobile computing by integrating four essential calculation tools into one powerful application. Whether you're a student, professional, engineer, or need reliable everyday math—this app delivers everything you need. FOUR SPECIALIZED CALCULATORS, ONE SEAMLESS EXPERIENCE Basic Calculator - Everyday Math Made Simple Clean, intuitive interface for daily calculations. Large, easy-to-read buttons with smooth animations and instant results. Perfect for shopping, budgeting, tips, and quick arithmetic. Familiar layout means you start calculating immediately. Scientific Calculator - Advanced Mathematical Power Professional-grade computational capabilities at your fingertips. Execute trigonometric functions including sine, cosine, tangent, and hyperbolic counterparts (sinh, cosh, tanh). Access inverse trigonometric functions (sin⁻¹, cos⁻¹, tan⁻¹) with radian/degree mode switching. Perform logarithmic operations: natural log (ln), base-10 log, base-2 log. Calculate exponentials (e^x, 2^x, 10^x), roots (√, ∛), and powers (x², x³, x^y). Use mathematical constants π and e with precision. Factorial function handles combinatorial calculations. Absolute value and reciprocal operations add versatility. Revolutionary F(x) evaluator lets you input custom expressions and evaluate at specific x values—perfect for homework and problem-solving. Advanced Graphing Calculator - Visualize Mathematics Bring functions to life with our sophisticated graphing engine. Plot parabolas by adjusting coefficients in real-time. Switch to multi-function mode for graphing multiple equations simultaneously, each color-coded. Support complex expressions: polynomials (x², x³, x⁴), trigonometric functions (sin(x), cos(x), tan(x)), inverse trig, hyperbolic functions, logarithms, exponentials, roots, absolute values. Combine operations for sophisticated expressions like "sin(x²)" or "x*cos(x)". Interactive zoom controls explore functions in detail. Pan across the coordinate plane with customizable axis ranges. Intelligent rendering handles discontinuities and asymptotes automatically. Vertex highlighting identifies maximum and minimum points. Perfect for calculus, algebra, trigonometry courses. Smart Unit Converter - Instant Conversions Comprehensive converter handles everything automatically. Convert between metric and imperial across five categories: • Length: millimeters to miles (mm, cm, m, km, in, ft, yd, mi) • Weight: milligrams to tons (mg, g, kg, lb, oz, st, t) • Temperature: Celsius, Fahrenheit, Kelvin, Rankine • Area: square millimeters to acres (mm², cm², m², km², in², ft², acre) • Volume: milliliters to gallons (ml, L, m³, fl oz, cup, pt, qt, gal) Intuitive interface shows both units with instant bidirectional conversion. Quick swap reverses units with one tap. CALCULATION HISTORY - NEVER LOSE YOUR WORK Every calculation automatically preserved. Access complete timeline organized by calculator mode. Each entry shows expression, result, timestamp, and mode. Tap any calculation to recall its result. Swipe to delete entries or clear all history. Color-coded badges: blue (Basic), purple (Scientific), green (Graph), orange (Converter).
