New: the AI Assistant answers your technical questions citing the app's own fault database. Error codes, diagnostics and diagrams still work offline.
IndexOS is the offline-first technical suite for technicians and companies: guided diagnostics, mapped fault codes, technical diagrams and manufacturer cards, in four vertical apps inside a single app.
THE FOUR VERTICALS
• ElectraIQ — Industrial automation: PLC, drives, motors, photovoltaics
• HVACIQ — HVAC and refrigeration: boilers, splits, heat pumps, chillers
• HorecaIQ — Professional kitchens: ovens, refrigeration, washing, coffee
• BASIQ — Building automation: alarms, CCTV, access control, KNX/DALI
WHAT YOU GET
• Step-by-step guided diagnostics: from symptom to cause, with suggested tools and spare parts
• Fault codes by domain, mapped and explained
• Wiring diagrams and manufacturer cards you can check in the field
• Technical glossary and Learn paths
• Intervention history
OFFLINE-FIRST
All content works without a connection: perfect for plants, boiler rooms, professional kitchens and technical spaces with no wifi.
FREE AND PRO
The free version includes the core domains of each vertical. IndexOS Pro unlocks the full library across all four apps with a single subscription:
• Monthly: €4.90/month
• Annual: €49.00/year
The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; you can manage or cancel it anytime in your App Store settings.

• Unlimited with IndexOS Pro
CONTENT
• ElectraIQ: Tesar and Thytronic protection relays, star-point fault, Thytronic alarm catalogue
IMPROVEMENTS
