Reten is the field app for fire-protection (PCI) maintenance technicians. Inspect equipment, attach photos, capture the client's signature and generate the official maintenance report under Spain's RD 513/2017 (RIPCI) on the spot, from your iPhone or iPad. No office, no paperwork afterward, no dependence on signal. BUILT FOR REAL WORK ON-SITE • Scan each piece of equipment by QR — extinguishers, hose reels (BIE), detection, alarms, emergency lighting. Each QR identifies the equipment and its history. • Checklist driven by RIPCI Annex II, with the correct periodicity (quarterly, biannual, annual) per equipment type. • Mark each item as OK or defect and add geotagged photos. • Capture the client's signature on screen, on-site. • Generate the maintenance report as a PDF instantly, ready to hand over. TRULY OFFLINE The work happens in basements, garages and warehouses with no signal. Reten works 100% offline: everything is recorded locally and syncs on its own once you are back online. Your reports are never lost. SYNC AND SAFE BACKUP Create an account and your clients, installations, equipment, inspections and photos sync securely across your devices. Switch iPhone or open your iPad and it is all there. MADE FOR ONE TRADE, NOT A GENERIC ERP Reten does not try to be a billing-and-stock ERP. It does one thing and does it perfectly: the field inspection and the signed report. Fast, direct and focused on the moment of truth. SUBSCRIPTION Reten is offered as a subscription (monthly or annual) with a trial period. The subscription grants full access to creating inspections, generating reports and cloud sync. Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the period. You can manage and cancel your subscription in your App Store account settings. Terms of Use: https://www.oscargarrucho.com/reten/terms Privacy Policy: https://www.oscargarrucho.com/reten/privacy
