Foculo is a small game about keeping one moving object in mind. A group of identical white cells drifts inside a dark circle. When a round starts, one of them is red. You get a second or two to find it. Then the red fades to white, and your target looks exactly like everything else on screen. The cells keep moving, crossing and overlapping. When they stop, you tap the one you were following. That is the whole game. There … Continue reading “Foculo”

The app covers all four lines — T1, T2, T3 and T4 — and their 105 stations. The routes drawn on the map follow the real tram tracks along the city’s boulevards rather than straight lines between stops, so you can see exactly where the tram runs. PLANNING A TRIPChoose a departure and an arrival station. The app draws the journey on the map, marks the stations along the way and lists every stop in order. When a trip needs … Continue reading “Casa Tram Nav”

Hijri Calendar shows today’s Islamic (Hijri) date alongside the Gregorian date,with a moon you browse by turning a dial. Rotate the outer ring to move through the days of the lunar month. The moon inthe center changes to match, and the panel shows the Hijri date, the day’sobservances, and the moon phase and illumination. Tap “Today” to return to thecurrent date at any time. FEATURES A NOTE ON ACCURACYDates are calculated and are meant as a guide. The start of … Continue reading “Moon Phase Dial”

Maze Mosaic Escape is a pipe puzzle game. Each level scatters pipe tiles across a board — swap them to build a connected path between the two endpoints. The twist: only ONE color of pipes forms the solution. A hint at the top tells you whether to connect the RED or BLUE pipes this round. The other color is a decoy. Connected pipes glow green so you can track your progress. HOW TO PLAY • Check the hint — RED … Continue reading “Maze Mosaic Escape”

Led Resistor  is a practical tool for electronics hobbyists, students, and makers who work with LEDs. CALCULATORS • Single LED — enter supply voltage and forward current, get the exact resistor   value snapped to E24/E12 series with 4-band and 5-band colour codes. • Series string — calculates the single dropping resistor for any number of   LEDs in series. • Parallel array — per-LED or shared resistor mode, shows per-branch and total   current. • Matrix (series-parallel) — handles … Continue reading “Led Resistor”

Place pads, IC footprints, and passive component pins from a built-in library. Features: Freehand drawing that auto-straightens to PCB routing angles Component library with DIP ICs (8 to 40 pin), resistors, capacitors, diodes, transistors, connectors, and more Configurable trace width and pad size in mm Place, move, rotate, and delete components Add text labels … Continue reading “A simple PCB layout tool”

a transistor simulator and learning tool for students, hobbyists, and anyone studying electronics. SIMULATOR Adjust supply voltage, input voltage, base/collector resistors, and gain with real-time sliders. The circuit solver computes operating point, currents, voltages, power dissipation, and junction temperature as you move each slider. Supports 12 device types: NPN, PNP, Darlington, N/P-enhancement MOSFET, N/P-depletion MOSFET, N/P-channel JFET, IGBT, phototransistor, and UJT. The display shows which region the device is in — cutoff, active, or saturation. BREADBOARD A pre-wired LED switch … Continue reading “Transistor Simulator App”

A color-based logic puzzle game. Fill every cell in the grid with blue or red while following three simple rules: The Rules:• Balance — Each row and column must have an equal number of blue and red cells. Some cells include number clues that tell you how many neighboring cells share the same color, giving you a starting point to work from. What’s Included:• 350 handcrafted levels across three difficulty modes (Easy, Intermediate, Hard) • Grid sizes range from 4×4 … Continue reading “Color Logic Grid”

TraceCanvas turns your phone into a tracing tool — place it above a sheet of paper, load any reference image, and trace directly onto the paper while watching the transparent overlay through the screen. Perfect for artists, kids learning to draw, handprint keepsakes, lettering practice, and anyone who wants to transfer an image to paper accurately. ─── HOW IT WORKS ─── Place your phone on a stand or holder above paper. Import a photo or drawing from your gallery. It … Continue reading “Trace Canvas”
