Debt 2 Income Calculator

£2.99
Nitrio Debt 2 Income Calculator, This debt to income ratio app has been created to help you calculate how much debt you can afford. Use this app to determine the ratio between your current income and current debt.

You can use this debt-to-income ratio calculator, also referred to as a DTI calculator, to figure out if you might be at risk of carrying too much debt or if you qualify for a loan of a given size. In general, lenders apply certain rules when evaluating someone that has applied for credit. The calculator performs both front-end, as well as back-end debt-to-income calculations.

Debt-to-income ratio
Percentage of monthly income that is spent on debt payments, including mortgages, student loans, auto loans, minimum credit card payments and child support.

Debt payments / income
For example: Peter earn \$10,000 a month. His total debt payments are \$3,800 a month. His debt-to-income ratio is 38 percent.
\$3,800 / \$10,000 = 0.38

Front-end ratio
A standard rule for lenders is that your monthly housing payment (principal, interest, taxes and insurance) should not take up more than 28 percent of your income before taxes. This debt-to-income ratio is called the "housing ratio" or "front-end ratio."

Back-end ratio
Lenders also calculate the "back-end ratio." It includes all debt commitments, including car loan, student loan and minimum credit card payments, together with your house payment. Lenders prefer a back-end ratio of 36 percent or less.
Ratios aren't carved in stone

Those recommended ratios (28 percent front-end and 36 percent back-end) aren't ironclad. In many cases, lenders approve applicants with higher debt-to-income ratios. Under the "qualified mortgage rule," federal regulations give legal protection to well-documented mortgages with back-end ratios (all debts, including house payments) up to 43 percent.

"That's been one of the bigger drivers (of affordability) because that is basically drawing a box around what's a qualified mortgage," says Tim Skinner, home lending sales and service manager for Huntington Bank in Columbus, Ohio. "A large portion of the lending community has decided to stay in that box."

Credit history
If you have a good credit history, you are likely to get a lower interest rate, which means you could take on a bigger loan. The best rates tend to go to borrowers with credit scores of 740 or higher.

Stop motion is an animated-film making technique in which objects are physically manipulated in small increments between individually photographed frames so that they appear to exhibit independent motion when the series of frames is played back as a fast sequence. Dolls with movable joints or clay figures are often used in stop motion for their ease of repositioning. Stop-motion animation using plasticine figures is called clay animation or "clay-mation". Not all stop motion, however, requires figures or models: stop-motion films can also be made using humans, household appliances, and other objects, usually for comedic effect. Stop motion can also use sequential drawing in a similar manner to traditional animation, such as a flip book. Stop motion using humans is sometimes referred to as pixilation or pixilate animation.

Illuminance Conversion

£2.99
Illuminance Conversion allows quick and accurate conversion between many units of measure, from one system to another. The Unit Conversion page provides a solution for engineers, translators, and for anyone whose activities require working with quantities measured in different units.

In photometry, illuminance is the total luminous flux incident on a surface, per unit area. It is a measure of the intensity of the incident light, wavelength-weighted by the luminosity function to correlate with human brightness perception. Similarly, luminous emittance is the luminous flux per unit area emitted from a surface. Luminous emittance is also known as luminous exitance.

The lux (symbol: lx) is the SI unit of illuminance and luminous emittance. It is used in photometry as a measure of the intensity of light, with wavelengths weighted according to the luminosity function, a standardized model of human brightness perception. In English, "lux" is used in both singular and plural.

Measurement units, Illuminance Conversion, Illuminance Converter, Foot-candles(fc), Kiloluxes(klx), Lumens per square centimeter(lm/cm2), Lumens per square meter(lm/m2), Luxes(lx), Microluxes(µlx), Milliluxes(mlx), Noxes(Nox), Phots(ph) and more.

Liquid Calculator

£2.99
Liquid calculator calculates the volume and weight of liquid inside given container at any given height of liquid.

The container shapes included such as capsule tank, cylinder tank, vertical capsule tank, vertical cylinder tank, rectangle tank and sphere tank.
More than 100+ liquid type for selection such as water, oil, mercury, acid etc.
Support for both metric and Imperial system.

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Water is, by far, the most common liquid on Earth. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena.

LED Resistor Calculator Plus

£2.99
LED resistance calculator use to determine the series resistor needed to connect various series combinations of light emitting diodes or "LEDs". LED resistance calculator will assist you pick the resistors make the connections for any number of LEDs.

Every (LED) light emitting diode has a current that they can handle safely. Going beyond it maximum current will damage the LED. So limiting the current through the LED with the use of a series resistor is a common practice.

LED resistance calculator will help you determine the value of the resistor so you can add in series with the LED to limit the current. Just input the indicated values and the result will be calculate automatically. The result include Resistor Value, Resistor Power Dissipation and Recommended Resistor Wattage.

Formula: R = (Vs - Vf * Nled) / If

Where:
Vs - Supply Voltage
Vf - LED voltage drop. The voltage drop on a LED depends on the color it emits.
If- LED current. The usual operating range of common 3 mm and 5 mm LEDs is 10-30 milliamps.
Nled - Number of LEDs in series

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable current is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. LEDs are typically small (less than 1 mm2) and integrated optical components may be used to shape the radiation pattern.

Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

* This method is not recommended for high current LEDs, which need a more reliable switching current regulator.

*This is a universal app that work for both iPhone and iPad.

Color Temperature Comparison

£2.99
Color Temperature Comparison Tool compare 2 difference color temperature on the fly. By input the color temperature value [Kelvin], color are show with color value in RGB and HEX, also indicate the color source for selected color temperature.

The Range of Color Temperature. The three primary types of color temperature for light bulbs are: Soft White (2700K – 3000K), Bright White/Cool White (3500K – 4100K), and Daylight (5000K – 6500K). The higher the Degrees Kelvin, the whiter the color temperature.

The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of a color comparable to that of the light source. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature is meaningful only for light sources that do in fact correspond somewhat closely to the radiation of some black body, i.e., those on a line from reddish/orange via yellow and more or less white to blueish white; it does not make sense to speak of the color temperature of, e.g., a green or a purple light. Color temperature is conventionally expressed in kelvin, using the symbol K, a unit of measure for absolute temperature.
