Store and organize ideas in one place. Add, edit, view, or share thoughts with a simple interface. Input ideas via a large plus button or by holding the icon. Edit descriptions and access ideas from a central dashboard.
The app analyzes audio input in real-time using FFT. It displays the frequency spectrum with options for graph scale, FFT window, decay time, and amplitude offset.
Analyzes device motion using accelerometers and gyroscope. Displays time series data and frequency spectra via FFT. Supports external USB accelerometer. Applies Hamming window and removes DC bias. Tracks three-axis movement with 0.02g sensitivity.
The app detects the device's orientation to find any 2D angle. It measures angles in degrees, radians, or as a gradient, holding the measurement for easy reading.
Transform audio by transferring the temporal structure of a source sound to a target sound while preserving its spectral properties. Apply spectral hybridization using envelope preservation and phase-sync processing.
Analyze spectra in real time using a microphone. Display waveforms and FFT data with adjustable frequency scales. Measure noise levels for approximate readings. Adjust FFT size for varying frequency accuracy.
Calculate for horizontal and vertical cylinders with flat heads, rectangular tanks, and horizontal vessels. Input dimensions and liquid height to get accurate results. Export calculations and share data directly.
The app provides an interactive unit circle to explore relations between angles and trigonometric ratios. It includes an exact trigonometric ratios table and a handbook of trigonometric formulas.
The app offers a clock with a clean interface and customizable appearance. Users can choose display colors, select 12 or 24-hour time, and opt to display seconds.
Helps users improve peripheral vision and speed reading. Users tap numbers in a to enhance visual search and attention. The tracks progress over time and encourages consistent practice to increase reading and recognition speed.
The app offers a chromatic tuner, metronome, and tone generator for musical practice. It provides precise tuning, customizable metronome settings, and various tone generation options for all instruments.
Create geometric shapes and figures using a grid. Draw points, lines, and angles. Explore symmetry through axial and central transformations. Practice fractions and calculate areas. Use tools for medians and diagonals. Export or save drawings.
