Panelos is an offline panel schedule, breaker directory, load balance, and handoff workbench for electricians. Build and edit a panel schedule, label breakers, review connected and adjusted load, check A/B leg balance, capture field evidence, and preview PDF or label packets before using a clean export credit. Panelos keeps the calculation and handoff trail visible instead of hiding the result in a black box. Built for panel-to-handoff work: - Create and edit panel schedules on iPhone and iPad. - Add breaker labels, rooms, notes, amps, poles, VA, and continuous-load state. - Review connected load, adjusted load, capacity, panel ratio, and A/B leg balance. - Keep circuit edit history with before/after values and reasons. - Capture field readings and photo evidence with local hashes. - Preview customer or AHJ packet drafts and panel + wire label packets. - Share watermarked previews for free. - Use clean export credits for watermark-free reports and labels. - Run voltage-drop calculations offline with visible inputs, steps, warnings, and references. - Save reusable panel templates for repeated jobs. Panelos stores the active workflow locally and does not require an account or cloud sync. The iPad layout adds a native sidebar and a wider centered workbench for repeated field and desk review. Panelos is not a replacement for licensed code books, engineering judgment, professional review, or AHJ approval. It does not reproduce NEC text or claim official compliance. Confirm the adopted edition, local amendments, field conditions, and final method before use. Start with a panel. Add circuits. Capture proof. Preview the packet.
