LadderTouchLite is an app to learn the basics of ladder logic, which is a graphical programming language. This app has two functions. You can learn about that mechanism by executing some of the prepared samples. And you can check your understanding with questions. -------Difference from the full version------- It doesn't show hints of questions. You cannot make your own ladders. ---------------ELEMENTS--------------- Input(yellow) Up to 5 elements. You can control the input signal by tapping the buttons at the bottom of the display. Virtual output(red) Up to 5 elements. Internal memory(gray) Up to 20 elements. Virtual output(red) and internal memory(gray) are the same for logical behavior. But the difference is in usage. The virtual output is the last element in the ladder logic chain. The Internal memory is for the processing element of the ladder logic chain. These are an imitation of the actual ladder logic with the output devices. Timer(blue) Up to 5 elements. The timer can be set from 0.1 seconds to 10.0 seconds. The setting unit is 0.1 second. The timer works only 'on delay'. This app does not include 'off delay'. On Delay. ---++++++++++ source -------++++++ destination Off Delay. +++---------- source ++++++++----- destination + ON - OFF Time flows from left to right Counter(green) Up to 5 elements. You can set from 1 to 50. There is no counter reset element in this app. Many other ladder logic software has it. The way to reset the counter is to stop running the ladder. All elements can be inverse in the source area. However, timers and counters cannot do it in the destination area. It is difficult to understand the inverse logic of a timer and counter in the destination area. --------------Other-------------- There is no function that connects to outer devices.
Stray Scanner
Capture color, depth, and IMU data using your device's LiDAR sensor. Export these datasets to your computer for machine learning and dense mapping projects. Streamline the process of collecting RGB-D data without complex calibration.
- Record color images
- Capture depth frames
- Export IMU measurements
- Estimate camera position
- Access camera calibration matrix
- Transfer datasets to desktop

Note: requires a device with LiDAR. The iPad Pro, iPhone 12 Pro or iPhone 12 Pro Max currently have LiDAR sensors on them. Stray Scanner allows you to record color, depth and IMU datasets and export them to your desktop computer. For machine learning and dense mapping applications, you need a dataset to work with. Stray Scanner allows you to collect RGB-D datasets with your iPhone. The recorded datasets contain: - color images - depth frames from the LiDAR sensor - depth confidence maps - camera position estimates for each frame - camera calibration matrix - IMU measurements Once recorded, the datasets can easily be moved to your desktop computer by connecting your device with a Lightning cable and accessing the files through Finder. Put your iPhone's LiDAR scanner to good use. No more fumbling around calibrating and configuring depth sensors. Shoot datasets straight from your iPhone.

Verdict
The clearest difference is rating: Stray Scanner at 5.0 against LadderTouchLite's 4.7. Stray Scanner also leads on chart position (#194 vs unranked). LadderTouchLite's advantage is ratings volume (226 vs 5) and update cadence (every 2 months vs every 6 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Stray Scanner holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: LadderTouchLite has 226 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 89% of LadderTouchLite's written reviews are positive against 75% of Stray Scanner's, so the app with the better star average is not the one people write more warmly about.
LadderTouchLite ships an update every 2 months, Stray Scanner every 6 months. The most recent releases landed on October 18, 2026 and October 13, 2026 respectively.
