HoursProof – Runtime Meter for Equipment Rental

A wireless runtime meter and billing tool for small equipment rental businesses

Problem

Someone wanted a wireless vibration-activated hour meter for small equipment rental businesses—generators, compressors, pumps—because existing devices require wiring or fail to accurately record actual runtime, leaving billing and maintenance to guesswork.

Solution

A magnetic vibration-sensing hour meter paired with a phone app: attach it to equipment, detect runtime vibration, accumulate hours, and sync via BLE. Generate per-equipment usage reports for billing and maintenance reminders.

Users

Small equipment rental companies, contractors, and site equipment managers.

MVP

Simple vibration+Ble hardware prototype; phone app records runtime per equipment; daily/weekly/monthly reports; maintenance reminders; CSV export for billing.

Revenue

Sell hardware at $25–40 per unit, app free; premium reporting and team collaboration at $9/month.

Why now

Low-power BLE chips and vibration sensors have dropped to sub-$25 product cost; small rental shops still use paper logs.
