SparkShift helps electricians stop rebuilding hours from memory: log OJT records, organize jobsites, open field calculators, and study for exams from one jobsite-ready app. Built for electrical apprentices, journeymen, foremen, and contractors, SparkShift keeps the paperwork and reference tools you already reach for close to the work. OJT AND WORK HOURS - Log apprenticeship and work hours from your phone - Add timestamps, notes, work categories, and optional location context - Track progress across union and merit-shop workflows - Review and export hour records before sharing with a training program, employer, union local, contractor, state board, or provincial authority FIELD CALCULATORS AND REFERENCES - Use NEC/CEC-aware calculators for common electrical work - Check voltage drop, conduit fill, box fill, wire sizing, load calculations, and other field references - Keep practical code-study tools nearby when service is weak or you are moving between jobsites EXAM PREP - Practice journeyman and master exam questions - Review explanations, study notes, and confidence feedback - Keep prep connected to the same trade record you use in the field JOBSITES, CREWS, AND RECORDS - Organize jobsite details, schedules, absences, and field notes - Support submitted-hour review and crew visibility for foremen and contractor workflows - Keep certifications, work history, community, and career tools in one electrician-first system SparkShift was built from real jobsite paperwork pain: lost logs, rebuilt hours, scattered notes, and reference tools spread across too many apps.
