About this app

Pocket Engineer helps technicians, service teams and homeowners diagnose equipment faults in the field. Describe the problem, add a photo, a sound or a vibration sample, and get a structured engineering report: likely root cause, fix steps, safety notes and the references behind them.

It is not a chat app. Every scan returns a report you can act on, keep and share.

Key features

1. Engineering diagnostic report — root cause, fix plan and technical tips in one structured report.
2. Regional cost estimates & supplier links — material and labour cost bands for your region (estimates, not quotes), with part codes and supplier links.
3. Hands-free field mode — hear each repair step read aloud while the current step is highlighted on screen.
4. Equipment registry — register pumps, HVAC units, machinery and home appliances, and review each one's fault history on a timeline.
5. Standards references & PDF reports — relevant ISO, OSHA, EN and manufacturer references are listed with each report; share it as a PDF.
6. Safety lock (LOTO) — high-risk repair steps unlock only after the safety checklist is confirmed.
7. Preventive maintenance plans — seasonal inspection schedules by equipment type, age and risk.
8. Quote audit — check contractor quotes and invoices for cost red flags and copy a negotiation draft.
9. Teams — a team owner shares a credit pool with technicians, with work-order planning, budget and approvals.
10. Encrypted backup — your records are backed up encrypted and can be restored on a new phone.

Pocket Engineer adapts its language from apprentice to chief engineer and works in 15 languages, including right-to-left scripts.

Honest by design

• Phone microphone and vibration readings are qualitative field aids, not calibrated ISO 10816 instruments or certified measurements.
• The credit cost is shown before every scan.
• Poor-quality captures are flagged, and you are asked to retake them before the scan runs.
• When the evidence is not enough, the report says so instead of guessing.
• You can report a wrong diagnosis; feedback is reviewed to improve quality.
• Reports support your judgement. Pocket Engineer is not a certification body, and its reports are not certified audit records.

What’s new

If camera access is off, nameplate scanning and photo capture now explain how to turn it on and let you choose a photo from the gallery instead. Minor visual fixes.
