PRISMA diagram outlining all LN apps that were initially identified and subsequently excluded or included for analysis. This figure follows the flow of the LN app identification and selection process. Our initial database search yielded 1152 applications, with 742 apps from the Google Play Store and 410 from the App Store. After all 1152 apps underwent a title and app description screening, 1148 apps were excluded due to their irrelevance to LN patients and the purpose of this review. This process left 4 apps eligible for a full app screening. Due to duplicates, 2 applications were eliminated from the second phase of screening. Following the full app screening, 2 apps were ultimately included in the final analysis
