Proband - Pedigrees Made Simple

Proband - Pedigrees Made Simple by The Children's Hospital of Philadelphia is performing strongly in select markets on the App Store Medical category. Its all-time peak was #1, achieved on 2026-09-16, and within the last 30 days it has matched that best of #1, though the average position of #56 suggests notable volatility. Currently, the app holds standout positions in three countries: #3 on Qatar's Top Free chart (unchanged), #6 on Peru's Top Free chart, and #12 on Pakistan's Top Free chart (down 2). The trajectory shows the app climbing sharply from its average and holding steady at the top of smaller markets, with only minor slippage in Pakistan.
