2/5 stars

Feature poor

The chart is nice, and the idea is good, but needs some basic features added to be useful. For instance, I entered 4.5 volts and it showed it as "4"! Not acceptable! Fractions of ohms, watts, and amps often have to be dealt with. Also, it should handle suffixes like "10k" meaning 10,000 ohms, and probably the European notation too (2k3 = 2.3k) Overall, the app shows promise but is not really useful in its current form.
