Intensity is a workout and fitness tool designed to assist you with both conditioning and strength training. It's suitable both for time based exercises such as interval training or circuits, and for reps based exercises such as those common in strength training programs. Being able to mix and match those two modes results in challenging, effective and fun workout programs! With Intensity, you can use the same tool for so different training regimens as stationary Tabata intervals and body weight circuits or running intervals, while keeping track of all the workouts in the same place. Each workout you complete is added to your workout log, for you to revisit later to review your training or to find that great workout you did last week and want to do again. With the "intensity control", you can adjust the difficulty of exercises by changing the duration or number of reps. This lets you increase the intensity as you get more and more fit, adding to the challenge. Intensity comes with a number of sample workouts to get you started and inspired: 6 different circuits (including the 7 minute workout), 2 high intensity interval schemes including Tabata, 2 isometric workout programs, 2 pyramid workouts and 1 maintenance program. You can easily change those programs to fit you even better, or create your own workouts.

About

Stellar

Read full description

Stellar is a motion comfort app designed for passengers who feel unwell during rides, flights, or boat trips. It combines real-time visual guidance with optional 100 Hz based audio to help reduce the sensory mismatch that often appears during travel. As your device senses motion, Stellar turns acceleration changes into calm, responsive visuals. Instead of leaving your eyes disconnected from what your body feels, the app gives you a stable visual reference that moves with the journey. Choose from three visual modes: Minimal offers clean peripheral guidance with a lightweight look. Interstellar turns motion into a spacious field of particles and stars. Live View uses the camera viewfinder with subtle edge effects, helping you stay visually connected to the real world. Audio support is optional. Research shows that sound at 100Hz might help alleviate motion sickness. You can choose a gentle melody calibrated around G2 = 100 Hz, a 100 Hz mono tone, or no audio. For the best experience, use headphones at a comfortable volume and enable transparency mode when available. Stellar is built to stay simple and local. It does not require an internet connection, does not collect or upload health data, location data, audio, or usage history, and only stores your preferences on device. Motion sensor access powers the core visual guidance, and camera access is used only for Live View. Please use Stellar while seated comfortably and holding your phone steadily. Do not use it while operating a vehicle. Results may vary from person to person. Stellar is not a medical product, has not been clinically validated, and should not be considered medical advice. If you experience discomfort, headache, tinnitus, or any other adverse symptoms, stop using it immediately. Stellar supports Chinese and English for the time being.
