Orientation Lock is a simple open source app to lock the screen orientation, for Android 5.0+.Features:Minimalist and lightweight: less than 100KB in size;Clean design: easy-to-use interface;Open source: no dependencies, no ads, no trackers.Why Orientation Lock?When using an Android tablet, you might find that some applications do not support landscape mode or specific orientations. This was quite troublesome for me. I tried several screen orientation locking apps available on the market, but they were overloaded with features. I simply needed an app to lock the screen orientation, so I decided to create one myself.The principle behind locking the screen orientation is very simple: it involves using a floating window to render a view in a specified orientation. This is just a straightforward application, and I wanted to keep it lightweight. Therefore, I implemented it using native methods without any third-party libraries. Pretty cool, isn’t it?

PAIesque helps you to track and improve your cardiovascular health using your heart rate data. It calculates a personalized activity score and monitors your Resting Heart Rate, giving you clear, actionable insights into your fitness progress—all on your device, with no subscriptions or data sharing.Prerequisite To get started, you must first install and configure Gadgetbridge to collect heart rate data from your compatible fitness tracker or smartwatch.How It Works: PAIesque is inspired by public research from the NTNU Cardiac Exercise Research Group (CERG). Their foundational studies on the PAI (Personal Activity Intelligence) metric demonstrates a powerful finding: "Our research shows that those who achieve 100 PAI or more every week over time live on average eight years longer than others." While PAIesque does NOT use the official PAI® algorithm (that is not known anyway), it applies this same, powerful principle: Your score rises faster when your heart works harder - so long both brisk walks and vigorous workouts move you toward your goal.Key Differentiators: Open & Transparent: Unlike “black box” scores, every calculation is based on the disclosed Karvonen Heart Rate Reserve (HRR) method in combination with a simplified Training Impulse Calculation (TRIMP). You always know how your score is determined. Universal & Consistent: Use it with almost any fitness tracker supported by Gadgetbridge (Amazfit, Garmin, Xiaomi, Fitbit, 100+ devices). Your scoring method stays the same even if you change devices. Privacy-First & Local: Everything is processed on your phone. Your heart rate data never leaves your device, and no internet connection or account is required. Note: This is an independent, community-developed application. It is based on public scientific principles and foundational exercise physiology methods but is not affiliated with or endorsed by NTNU CERG, and its score is distinct from the proprietary Personal Activity Intelligence (PAI®) metric.
