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. Customers can insert the appointment directly into their calendar using a QR code. -> File Attachments: Attach up to 20 files to a customer. -> Design Options: Allows you to set your own title bar color.

About

Controlduino

Features
Read full description

Monitor, record, chart and export combustion data in real time from your iPhone or Mac. Lambda Tuning is the official app for the Controlduino 01D21 device, featuring a wideband lambda sensor LSU 4.9, EGT sensor (exhaust gas temperature up to 1000°C), and RPM measurement. Designed for professionals and enthusiasts who want to control combustion: tuning engines, burners, boilers, or any system with an air-fuel mixture. CUSTOMIZABLE APP: The app is highly configurable, whether you use a single Controlduino 01D21 device or several: choose which values to display from each connected device, customize the gauges and views, and adapt the app to your specific needs. Each device can have its own custom view based on the data you want to monitor or record. DATA VISUALIZATION: View readings in numeric format or through circular gauges and linear bars, designed for quick and intuitive reading. SIMULTANEOUS MULTI-CONNECTION: Connect from 1 to 8 units in parallel. Thanks to parallel processing, the app can receive data from up to 8 devices at 100 samples per second each, displaying, storing and charting all results simultaneously. Ideal for engines with multiple carburetors, independent cylinder banks, or systems with multiple simultaneous measurement points. LOGGING AND EXPORT: Store data sessions and export them in CSV format for further analysis. You can also chart results directly in the app and export graphs as PDF. CONTROLDUINO 01D21 DEVICE CONFIGURATION: Configure your device directly from the app: fuel selection, oxygen and RPM measurement settings, data selection for the device's display, and analog output curve adjustment. ARDUINO COMPATIBLE (OPTIONAL): The device sends data simultaneously to iPhone/Mac via Bluetooth and to Arduino boards via SPI. It includes an easy-to-use Arduino function library, with no resource consumption on the microcontroller (calculations are performed by the device itself). From the app, you can customize the device parameters (lambda, RPM, analog output...) to adapt it to your specific use case. These adjustments also affect the data Arduino receives, allowing you to obtain more accurate readings for each application. WHO THIS APP IS FOR: • Automotive professionals and enthusiasts who tune air-fuel mixture in combustion engines. • Tuning enthusiasts who need to monitor air-fuel mixture in real time to optimize engine performance. • Technicians and installers working with burners, boilers, and combustion systems. • Makers and Arduino users who want to integrate combustion sensors into their projects. IMPORTANT: To visualize and record data in real time, you need the Controlduino 01D21 device hardware. Without it, you can open binary files recorded by other users who do have the Controlduino 01D21 device, export to CSV, chart data, and save graphs as PDF. SAFETY WARNING: The lambda sensor heats up during operation. Properly installed in the exhaust system, there is no risk, but during testing do not leave it unattended on plastics or flammable materials, as it can damage them or cause a fire. In applications with running engines, burners, or boilers, exhaust gases reach very high temperatures and can be toxic. Make sure to take the necessary safety precautions.
