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, export your data into VCF or CSV files and print a customer record (PDF export). Additionally, this app has a Dark Mode and the ability to save customer images.
