Jeremy Kaigler built SparkShift because he was tired of losing paper logs, refilling the same forms, and bouncing between generic apps that did not fit the trade. Every major workflow on this page started as something he actually needed on the job, from hour tracking to free NEC calculators to crew records that still work when service gets weak.
From the founder
“I built SparkShift because I was tired of losing my paper logs and filling out the same forms every week. Every feature we ship is something I actually needed in the field.”
Jeremy Kaigler • 5th Year Apprentice • IBEW Local 58
Logging, calculators, and key references keep working offline on the jobsite, then sync once service returns. Review plan details, store listings, and local documentation rules before relying on any export or calculation.
Built for apprentices
Log work the same day, keep categories clean, collect sign-offs, and keep your records ready before your program asks for them.
Free tier available
Why SparkShift Feels Different
The fastest way to trust SparkShift is to understand who built it, how it behaves when service drops, and where electricians can help shape the next layer of the product.
Founder-Led
SparkShift started because a trade worker got tired of losing paper logs, rebuilding hours, and relying on generic apps that did not match the field. The public guides still carry that same trade-first voice.
Jobsite Reliability
Weak basements, dead zones, and half-finished service installs are normal. SparkShift keeps key calculators, logs, and references available when the signal does not cooperate, then syncs when service comes back.
Founding Community
The forum is still in founding mode, so the best move is to make the early threads useful. Start with concrete field questions and real jobsite stories instead of waiting for the archive to appear by itself.
SparkShift brings together the work electricians usually split across paper logs, calculator apps, screenshots, bookmarked code pages, and scattered notes. It was shaped in the field for apprentices, journeymen, foremen, and contractors who need one place to keep the important parts of the trade.
