Night clock. Choice of 12 or 24 hr format. 12hr format has an extra "." to denote pm hours. Whole rainbow of color choices and variable brightnesses. Guide button leads you to separate page (and disappears after 3 seconds if not tapped). Set color/brightness by tapping on digits so you are less likely to change something while just handling the clock in the dark. Be sure to plug in because it does draw power. Single tap: change brightness. Double tap: change digit color. Swipe the digits to change background color to bright red to use as a night flashlight. Swipe digits again to get back to black blackground (and old brightness). Both brightness change and color change are orientation-dependent. Single tap in Portrait mode increases brightness, in Landscape decreases brightness. Similarly, double-tap in Portrait cycles one way and reverses if in Landscape. Display another time zone: If you are living in Maui but your officemates are all in Chicago and you want to keep track of what time it is there. Digits are italic if the time zone is enabled. AutoLock is turned off in the app so the clock continues to display during the night but with v1.80 and up if the phone is unplugged or power is lost then the display will turn off after the number of minutes set in the AutoLock feature. If AutoLock is set to never then the display will stay on but at the lowest power consumption setting. A 1/2 full battery icon is displayed if battery is being drained (see screenshot for largest iPhone).

About

AmpGuide

Read full description

AmpGuide is an electrical field reference and calculator suite for electricians, apprentices, inspectors, engineers, solar installers, EV installers, and serious DIY customers. It brings common jobsite calculations into one offline workbench so you can check numbers, compare options, and keep notes without digging through separate utilities. Version 2.5 includes 27 calculators plus Inspection Brief for saved Jobs. The app reviews the calculations in a job pack, assigns a readiness score, flags failing results, calls out missing core checks, and suggests the next actions to document before review. Core tools include: - Wire size calculator with ampacity and voltage-drop checks. - Voltage drop for copper or aluminum, single-phase or three-phase. - Ampacity tables with ambient and conductor-count derating. - Breaker sizing for continuous and non-continuous loads. - Conduit fill, box fill, Ohm's Law, and three-phase helpers. - Standard and optional method service-load calculations. - Transformer kVA sizing and NEC 450.3(B)-style OCPD guidance. - Wire pull tension and jam-ratio checks. - Grounding electrode and equipment grounding conductor sizing. - Motor FLC, lighting demand, range demand, dryer demand, and fault-current tools. - Solar PV string, EV charger, parallel conductor, burial depth, and bid-estimate workspaces. - Conduit bender and wire color, resistor, thermocouple, and plug-pinout references. AmpGuide is designed for quick field decisions and reviewable planning. It is an informational reference and calculator, not a substitute for the official NEC, engineering judgment, jobsite conditions, permits, inspections, or authority-having-jurisdiction requirements. Always verify final work against currently adopted code and local requirements. Saved calculations and job notes stay on the device. AmpGuide does not request protected device permissions.
