GedGap is a genealogy tool that can help you plan, rate and prioritize your research plan. Just import your GEDCOM file from your family tree web site or genealogy software and GedGap can:
• Analyze and score each of your sources to reveal gaps in the reliability of your birth and death entries,
• Prioritize an individual's research based on the quality and completeness of sources,
• Determine a confidence rating in your sources being proof of birth and death events,
• Provide brief tips on the status of birth and death research,
• Allow you to add brief notes to an individual's research,
• Allow you to set flags for missing sources being proof of birth and death events, whether research is complete or has ceased, and
• Produces various reports on your research plan.

The internal scoring engine is customizable for different birth and death source types, e.g. birth index, death certificates, etc.

Locks up when scrolling until Force Quit

Not helpful since it locks up once import finishes and requires a Force Quit.

I shouldn’t really review this app since it crashes EVERY time I try to open a gedcom. ‘Nough said?

Developer Response ,

Apple has kindly enabled the ability for developers to response to reviews. Thank you for your review and I am sorry to hear of your issues with version 1.0 of GedGap. There was an issue with the initial version of the app with loading some Gedcom files causing a crash, which has been resolved in version 1.1. If you are having problems loading your Gedcom file, please contact me from our website and I can help resolve the issue for you.
