Current Week vs Gnist

Current week is a simple and easy-to-use app that shows the week number for the current week. You can also find out the current week number from a specific date. The app includes a home screen and lock screen widget that displays the week number. There is also an Apple Watch app available with a complication so you can see the current week number right from the watch face. The app uses the current date on the device to get the current week number so it should work in all timezones.

Gnist is a fast, precise calculation tool for electricians and electrical professionals - built around NEK 400 (and IEC 60364). Size cables and overcurrent protection, calculate voltage drop, short circuit and earth-fault disconnection, check selectivity, and size heating cable, EV charger, solar/PV and motor starting - all in seconds. CALCULATORS - Cable & fuse - cross-section, protection, reference method, correction factors - Voltage drop - DeltaU in percent over the cable length - Short circuit - Ik and adiabatic check - Earth fault & disconnection - Zs requirement for automatic disconnection - Selectivity - indicative assessment between protective devices - Heating cable - power and spacing by room and substrate - EV charger, solar/PV, motor starting - Basic calculator - Ohm's law, power, energy, PE, AWG - Build installations as a tree, get warnings and single-/multi-line diagrams - Save projects and export PDF LANGUAGES The app is available in Norwegian, English, Swedish and Danish. You can choose the electrical standard (NEK 400, IEC 60364, SS 436, DS/HD 60364, DIN VDE 0100, SFS 6000, BS 7671) independently of the app language. PRIVACY Everything runs locally on the device - no account, no server, no tracking. IMPORTANT Gnist is a guidance tool and does not replace independent design.
