As part of your participation, you’ll be asked to complete surveys about your thoughts, feelings, and behaviors. With your permission, the app may also collect sensor data—such as activity levels, environmental context, and smartphone usage patterns—to help researchers better understand cognitive and behavioral health in individuals with Down syndrome. Your app experience is customized by the study team using the MetricWire Research Portal. All data you submit is securely protected by MetricWire and managed by the ARC-DS study team. You remain in full control of your data—you can review what you’ve shared, choose to leave the study at any time, or delete your data if you wish. If you have any questions, please contact the ARC-DS study team using the contact information they’ve provided. ARC-DS by MetricWire makes research participation simple, secure, and meaningful—designed with transparency and user control at the core. ## ARC-DS Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/0d/97/9f/0d979ff0-67fd-8dd1-6392-bd121be26b9a/simulator_screenshot_7853497E-E4EF-41AA-828C-DDBCA5D07B4D.png/1242x2688.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/f3/90/bc/f390bce6-0c28-8bb4-59d6-b66ae728449a/Simulator_Screenshot_-_iPhone_11_Pro_Max_-_2025-04-23_at_18.20.06.png/1242x2688.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/4d/5c/35/4d5c3560-3fd5-4eb4-5460-1e526119f420/Simulator_Screenshot_-_iPhone_11_Pro_Max_-_2025-04-23_at_18.20.09.png/1242x2688.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/9e/83/86/9e83868c-12d8-d720-39f2-27eb33700766/Simulator_Screenshot_-_iPhone_11_Pro_Max_-_2025-04-23_at_18.20.12.png/1242x2688.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/0a/3d/97/0a3d9716-ee05-a48c-d599-73760d545fce/Simulator_Screenshot_-_iPhone_11_Pro_Max_-_2025-04-23_at_18.20.30.png/1242x2688.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/f7/7d/e8/f77de80c-1569-1568-9116-ecf53b5aeac0/Simulator_Screenshot_-_iPhone_11_Pro_Max_-_2025-04-23_at_18.21.37.png/1242x2688.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/06/26/f9/0626f9e2-e441-f8d2-ec87-3c745298d41e/Simulator_Screenshot_-_iPhone_11_Pro_Max_-_2025-04-23_at_18.21.31.png/1242x2688.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/c3/72/0d/c3720d1f-4215-b01f-cb09-dcdf9021cde2/Simulator_Screenshot_-_iPhone_11_Pro_Max_-_2025-04-23_at_18.21.25.png/1242x2688.png) ## ARC-DS Available In - [Austria](https://apptail.io/app/arc-ds-USDv/austria) - [Australia](https://apptail.io/app/arc-ds-USDv/australia) - [Azerbaijan](https://apptail.io/app/arc-ds-USDv/azerbaijan) - [Czechia](https://apptail.io/app/arc-ds-USDv/czechia) - [Germany](https://apptail.io/app/arc-ds-USDv/germany) - [France](https://apptail.io/app/arc-ds-USDv/france) - [United Kingdom](https://apptail.io/app/arc-ds-USDv/united-kingdom) - [South Korea](https://apptail.io/app/arc-ds-USDv/south-korea) - [Kuwait](https://apptail.io/app/arc-ds-USDv/kuwait) - [Kazakhstan](https://apptail.io/app/arc-ds-USDv/kazakhstan) - [Lebanon](https://apptail.io/app/arc-ds-USDv/lebanon) - [Lithuania](https://apptail.io/app/arc-ds-USDv/lithuania) - [Nigeria](https://apptail.io/app/arc-ds-USDv/nigeria) - [Netherlands](https://apptail.io/app/arc-ds-USDv/netherlands) - [Pakistan](https://apptail.io/app/arc-ds-USDv/pakistan) - [Poland](https://apptail.io/app/arc-ds-USDv/poland) - [Sweden](https://apptail.io/app/arc-ds-USDv/sweden) - [Türkiye](https://apptail.io/app/arc-ds-USDv/turkey) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
