Point Load Test vs PDF2Audio
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Point Load Test
This application facilitates point load testing for geotechnical analysis by connecting to a compatible device via Bluetooth. It automates specimen measurement, calculates test results, and allows for custom equation definitions for strength determination. It also supports Ultrasonic P-Wave Velocity measurements.
- Bluetooth connectivity to PLT device
- Automated specimen measurement
- Point load test result calculation
- Customizable strength determination equations
- Graphing of load vs. equivalent core diameter
- Ultrasonic P-Wave Velocity measurement support

*NOTE: This is a new version of the PLT app. The old version will remain listed in the meantime but will be removed soon. The Point Load Test Application was designed to be used in conjunction with a GCTS PLT-2W. This application allows the user to easily perform tests and record data by connecting to a PLT device via Bluetooth. The device will output load and displacement from a pair of sensors, which will be read by the app and used to calculate point load test results. The app allows two-step calibrations of these readings, and also can obtain pre-loaded calibration factors from within the PLT-2W. Using this application, specimen measurements can be made with ease. By simply placing the specimen in the apparatus as shown in the application and applying a small load, the application will automatically calculate the dimension of the specimen in that axis. This app can be used with diametral, axial, or irregular specimens. In addition, the application can be set to reuse certain dimensions, so if a core sample is used, the application can be set to use the same diameter for each specimen tested. The operator can also define a custom equation for determination of the unconfined compressive strength from the point load strength index as calculated by the test. The application will automatically graph the load versus equivalent core diameter and automatically calculate the unconfined compressive strength for the rock specimen. This app also allows the measurement of Ultrasonic P-Wave Velocities when paired with a ULT-2 or ULT-200.

Turn any PDF — or web article — into audio you'll actually listen to. PDF2Audio reads your PDFs aloud with natural AI voices — word for word, or as a lecture or a two-host podcast. Books get their own chapters, so a whole book plays like an audiobook. Paste a link, or share a page from Safari, and listen to the article instead of reading it. WHY PEOPLE USE IT • Read aloud: every word of your PDF, narrated clearly. • Book mode: whole books, with chapters you can jump between. • Lecture and podcast styles that explain the material. • Web articles: paste a link or share from Safari — the article, not the menus and ads around it. • Starts playing in about a minute — listen while the rest is made. • Mini player: audio keeps playing while you move around the app. • Continue listening: pick up where you stopped, right from the Library. • Quiz, key terms and section summaries to help you study. • Read along with the full transcript. • Sleep timer, adjustable speed, and your place saved — on iPhone and on the web. • Page range: convert just the pages you need. • Scanned PDFs work too — text recognition runs on your device. • 13 voices, 18 languages. • Library, playlists and downloads for offline listening.

Verdict
The clearest difference is in-app purchases: Point Load Test at none against PDF2Audio's 4. Point Load Test also leads on iOS requirement (12.2 vs 17.0). On price, update cadence, ads and device support there is nothing between them.
