“Buoyancy” app brings to you a guided tour to acquaint yourself with the lab experiment that demonstrates the buoyancy. The app brings to your finger tip the step by step protocol for the experiment. The “Buoyancy” exhibits all the apparatus required for the experiment. Also, the app illustrates the entire procedure for the experiment to show the buoyancy. Let us explore the offerings of the “Buoyancy” app. The user first gets acquainted with various glassware and apparatus used in the experiment. The user is then guided by the app to perform the experiment with explicit instructions. The experimental procedure is followed by interpretation of the observation and conclusion. This robust application is a great teaching and learning tool for students, educators and teachers wanting to study or teach about the buoyancy. FEATURES: - 3D models that you control, each structure clearly labeled with useful all apparatus information. - Audio guide available about buoyancy. - Rotational models (views from different angles) - Tap and Pinch Zoom - zoom into and identify about the buoyancy.

Verdict
The clearest difference is update cadence: Touch Fluids at every 13 months against The Buoyancy's every 56 months. Touch Fluids also leads on price ($0.99 vs $1.99). The Buoyancy's advantage is iOS requirement (12.0 vs 17.2). On ads, in-app purchases and device support there is nothing between them.
