Angle Meter

Read full description

Angle Meter: Inclinometer is a clean and practical tool for measuring angles, tilt, slope, and device orientation with your iPhone. Use it for everyday tasks, DIY projects, leveling, setup work, and quick measurements whenever you need a simple digital angle meter. Main Features: • Measure angles in real time • View main and perpendicular values • Choose between Standard, Simple, Percent, and Combined value types • Save measurements for later • Add notes to saved measurements • Share saved results easily • Save measurements to Photos • Customize the display with options such as decimal values and ruler scale • Use Light, Dark, or System appearance • Simple and easy-to-read interface • Core measuring features work offline USE ANGLE METER FOR: • Checking tilt and slope • Leveling furniture or objects • Measuring roof or surface angles • Checking solar panel tilt • Workshop and DIY projects • Setup and alignment tasks DESIGNED FOR SIMPLICITY Angle Meter: Inclinometer is designed to make measurements quick and easy while providing flexible display and measurement options. Whether you need a quick angle reading or want to save and organize measurements for later, everything is available in a simple interface. IMPORTANT Measurements are calculated using your iPhone's built-in sensors. Accuracy may vary depending on device hardware, sensor calibration, and environmental conditions.

Chemy+ is an infinite canvas for understanding chemistry: type an equation and get the balanced right-hand side drawn atom by atom, build compounds by joining atoms with your finger, or drop elements into the Lab and watch what reacts. EQUATIONS • Type the reactants ("2H2 + O2 =") and Chemy+ completes and balances the equation. • Every product is drawn with its bonds and CPK colors; tap one for molar mass, bonds and composition. • Write both sides and the balancing happens on your device, offline. • Write the formula by hand with your finger or Apple Pencil: whatever is recognized goes into the same engine. BUILDER AND LAB • Drop one atom onto another and they bond by valence: covalent, polar, ionic or metallic. Valence electrons orbit the atom you touch. • Every body draws its real structure, with single, double and triple bonds, charges and ions. • Cut a bond with the scissors and see what it cost in energy and what is left: ions if it was polar, radicals if it was not. • Draw an organic skeleton as lines and drop it into the Lab fully built: each vertex is a carbon and hydrogens are filled in for you. • Place zones of heat, cold, pressure, catalyst, aqueous solution or current and change what forms and why. REAL CHEMISTRY • 118 elements with search, families, electronegativity, configuration and melting and boiling points. • 174 reactions verified against general and organic chemistry sources, each with its chapter. • Activity series, acid-base with live pH and indicators, states of matter, electrolysis and the Daniell cell. • Functional groups and IUPAC names for what you build. • "How to make it": Chemy+ traces the route from the elements in your palette and unfolds it on the canvas, step by step. MADE FOR LEARNING • 50 challenges across five levels, with no points and no leaderboards. • A history of everything you solved and built. • Spanish and English. • No accounts and no ads. Your canvases stay on your device. Product prediction for open equations uses artificial intelligence and is always verified against the on-device chemistry engine before being shown; only the equation text is sent. CHEMY+ PRO (OPTIONAL) • Free forever: equations, the Lab, the builder, the periodic table, challenges, molecules and organic chemistry, with up to 3 canvases and 10 AI predictions a day. Balancing an equation typed with both sides is unlimited. • Chemy+ Pro removes those caps: unlimited canvases and AI predictions with no daily limit. • Monthly or annual subscription; the annual plan includes a 7-day free trial. • Payment is charged to your Apple ID account. The subscription renews automatically unless you cancel it at least 24 hours before the end of the period in your Apple ID settings. • Your canvases are yours: if Pro ends, every one of them still opens and can be edited.

Verdict

The call

The clearest difference is in-app purchases: Chemistry Equations at none against Angle Meter's 1. Chemistry Equations also leads on ads (none vs shown) and iOS requirement (17.0 vs 26.2). On price and device support there is nothing between them.
