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.

A long chat, article, feed or web page won't fit on one screen – so you take a stack of screenshots. Then you're stuck stitching them by hand: hunting for where one frame meets the next, trimming edges, lining things up. It eats your time, the seam still shows, and the image comes out crooked. Stitcher gets it right in seconds – one clean image with no visible seams, no repeated bars and no scrollbar. THREE WAYS TO MAKE A LONG SCREENSHOT • Import screenshots – pick them in the app or send them straight from Photos with Share, and let the app do the rest • Web Capture – paste a link or share a page from Safari, and Stitcher grabs the whole thing • Scrolling Capture – start a screen recording, scroll through a chat, feed or article, and the app turns the video into one long screenshot. Already have a recording? Send it from Photos WHY YOU CAN'T SEE THE SEAM Stitcher finds exactly where two frames overlap and joins them right there. It auto-aligns the images, removes repeated headers and toolbars, and hides the scrollbar, the Dynamic Island and the home indicator. A REAL EDITOR – NOW FREE • Hide what's private before you share: blur, pixelate or drop a solid box over names, numbers and personal details • Point things out: arrows, a brush and text • Trim what you don't need – at the edges and even from the middle AI THAT DOES THE BORING PART • AI-Censor finds names, phone numbers, emails, card numbers, amounts and faces, and hides them one by one or all at once • Ad Detector finds ads in your stitch and cuts them out PRIVATE BY DEFAULT Stitching, editing, AI-Censor and Ad Detector all run right on your device. Your screenshots are never uploaded, and no account is required. Import and Scrolling Capture don't need the internet at all – works on a plane, works offline. Anonymous usage statistics can be turned off in Settings. FEATURES • Stitch up to 50 images into one picture • Crop the edges and cut out what's in the middle • Automatic scrollbar, Dynamic Island and home indicator removal • Redaction: blur, pixelate, solid box • Arrows, brush and text for emphasis • AI-Censor – automatically finds and hides names, phone numbers, emails, card numbers, amounts and faces • Ad Detector – automatically finds ads and cuts them out • Export to Photos or to PNG, JPEG and PDF files. JPEG quality is adjustable, and a long PDF can be split into pages • Export several projects at once • Project history, auto-delete for old stitches and removal of the originals (optional) • Import screenshots, screen recordings and links from the share sheet • Live Activity – leave the app while a really long stitch is being made TERMS Stitcher Pro is available as a weekly auto-renewable subscription or as a one-time lifetime purchase. Payment is charged to your Apple ID when you confirm the purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel it in your App Store account settings.
