This simple customer database application is designed for small companies for easy and secure customer management on smartphones and tablets, separated from private contacts. It is possible to sync your data with a (self-hosted) MySQL server to prevent loss or defect of your mobile device. This also allows to sync the data with multiple devices. In addition to that, it has tools for the EU-GDPR and you can group customers, manage customers birthdays and vouchers, write newsletters, import customers from VCF files and export your data into VCF or CSV files. Additionally, this app adapts the Dark Mode and has the ability to save customer images. The app shows the names of people saved in the customer database for incoming calls if you activate this in the iOS settings under "Phone" -> "Block and identify calls". Because of its high flexibility, the application is also often used in non-enterprise areas, such as teachers' management of parent contact information. Additional features that can be unlocked via in-app purchase: -> Custom Fields: also drop down selection lists and sorting by these fields is supported. -> "Input-Only-Mode": Optional activatable mode that allows only data entry. For example, the device can be handed to showroom visitors. -> Calendar: Manage customer appointments.
