Engineering FMEA for iPad Engineering FMEA for iPad is designed for fast, structured engineering documentation with a strong educational focus. The primary purpose of the app is to support learning and applying systematic thinking in engineering problem analysis through the FMEA methodology. The app can also be used for practical needs such as FMEA reporting, rapid preparation of preliminary data for urgent meetings, team selection, and tracking corrective actions. A sample Wind Turbine FMEA project, including references and tutorial content, is automatically added on first installation (clean install required). Reporting Capabilities • The content of the full report can be customized using settings options. • A complete report preview is generated when the Report button is pressed. • Each section includes its own dedicated report button for partial reporting. • Users can upload and save project-specific logo images by tapping the logo area on the notification page. Supported Sections 1. Notification Report with an editable photo 2. Team Management Table 3. FMEA Table for Design or Process FMEA • Severity, Occurrence, and Detection scale descriptions automatically adapt to the selected FMEA type • Design and Process FMEA entries can be combined within a single table 4. Document Review Table 5. Recommended Actions Report Data Editing & Reuse Any previously entered record in a table can be recalled into the entry fields by selecting its row. After editing, updates can be saved or recorded as a new entry using the command buttons. Reporting & Sharing The full report is previewed before publishing. Sharing options allow the report to be opened with third-party apps such as PDF editors and viewers. Help & Guidance Context-specific help content is available in the Settings tab of each project.

Verdict

The call

The clearest difference is price: Electronics Engineer Helper at Free against Engineering FMEA's $4.99. Electronics Engineer Helper also leads on update cadence (monthly vs every 3 months) and device support (3 vs 1). Engineering FMEA's advantage is in-app purchases (none vs 2) and iOS requirement (9.0 vs 17.0). On ads there is nothing between them.
