MarkPlan turns any blueprint into a living record of the work. Mark each installation right on the PDF, take the photo, and it's documented — date, time, and who did it, always on hand when you need it. Built by an electrical contractor for daily use on real job sites, MarkPlan works for any trade that works with plans: electricians, plumbers, HVAC installers, and general contractors. WORKS WITH NO SIGNAL, ALWAYS Basements, elevator shafts, rural areas. MarkPlan measures, marks, and saves everything locally on your device. Nothing depends on having wifi at that moment — once you're back online, everything syncs on its own. EVERY PERSON, THEIR ROLE Invite your team with clear permissions: • Supervisor and Editor: mark, measure, and document • Viewer: read-only, always free, no limit A HISTORY THAT DOESN'T DISAPPEAR Every photo and status change is logged with date, time, and author. When the client calls months later about a repair, the answer is already there — no need to go find it on site. WORK PHASES The same point goes through rough-in, trim-out, and final inspection. MarkPlan keeps up: each phase is documented separately, without losing the history of the ones before it. COMPLETE DOCUMENTATION PER PROJECT Upload the plans, add measurements, photos, and videos, leave comments. The whole project, organized in one place — a real record of what was done, not scattered photos lost in your phone's camera roll. Download MarkPlan and try the full workflow on your next job.
