Oversec
APK
Oversec transparently encrypts and decrypts any text in any app You can use it to exchange private encrypted and covert chat- or email messages or store your own encrypted notes on your phone. See our demo videos: * Introduction * Encrypting Emails * Encrypting Images Oversec is completely agnostic of the subjacent app, it works with Whatsapp™, Line™, Snapchat™, Instagram™ or any other chat app. It also supports sending and receiving PGP encrypted messages with the Gmail™ or any other Email app. End-to-End Encryption was yesterday. Oversec introduces "Eye-to-Eye" encryption. Encrypted data is only decrypted while it is shown on the screen! No clear text is ever persisted and thus cannot be extracted from the file system or accidentally be backed up into the cloud. We also carefully designed Oversec so that it doesn't require internet access. Because of that, you can rest assured that no decrypted information can ever leave your device. How it works: Oversec constantly monitors the text on your screen. When it finds an encrypted text, it tries to decrypt it and then shows the decrypted text as an overlay in place of the encrypted text. Conversely, it can read text out of an input field, encrypt it, and then put the encrypted text back into the input field. In order to encrypt a text, Oversec shows a button next to an active input field. After having entered the secret text, tapping that button makes Oversec read the text, encrypt it and put back the encrypted text into the field. It is now ready to be sent in the subjacent app as usual - the app doesn't even know that it is sending encrypted data! Oversec also features a unique way of encoding the encrypted messages. It stores the encrypted text in invisible (zero-width) characters and let's you add decoy text at the end. That way, a message will just show e.g. "The sun is shining!" with no visible sign of any encryption, whereas in reality it contains a hidden encrypted message. You may also encrypt and send photos through Oversec - its unique camera mode even allows you to take and send an encrypted photo without ever storing the original photo on the device. Oversec encrypts your data either using symmetric keys (using ChaCha20 cipher + Poly1305 MAC ) or using asymmetric PGP encryption (making use of the OpenKeychain app). The code is open source and can be found here. This app uses Accessibility services.

PAIesque
APK
PAIesque helps athletes and fitness enthusiasts monitor their training through a simple three-step logic: 1. Measure training impulse (TRIMP) — The faster and longer your heart beats, the higher your daily score. 2. Analyze patterns over time — Track how your TRIMP accumulates and distributes 3. Monitor your body's response — Compare how your body reacts to training load PAIesque is different from commercial fitness apps (e.g. Garmin, Whoop, Polar). Every metric comes from published, peer-reviewed research with transparent methods that can be calculated from heart rate data alone. The app only includes metrics we can verify and reproduce from first principles — no proprietary black boxes, no undisclosed algorithms. And, all your data stays on your device. 1. TRIMP: • Banister TRIMP — The original exponential model with sex-specific coefficients (a=0.64/0.86, b=1.92/1.67) [Banister, 1991; Morton et al., 1990] • iTRIMP — Individualized TRIMP with customizable b coefficient (1.5-4.0) [Stagno et al., 2007; Akubat et al., 2012] • LT-TRIMP — Lactate Threshold-based model with β coefficient (0.04-0.11) and smooth transition at LT [Cheng et al., 1992; Mader et al., 1976; Gaesser and Poole, 1986] • PAI-esque — PAI-inspired metric using EWMA (not the official commercial algorithm) [Nes et al., 2017; Kieffer et al., 2021] 2. Patterns over time: • Intensity zones — Time and TRIMP spent in low/moderate/high zones (polarized training model) [Seiler and Tønnessen, 2009; Stöggl and Sperlich, 2014] • EWMA — Exponentially Weighted Moving Average for rolling loads (more sensitive than simple averages) • ACWR — Acute:Chronic Workload Ratio for injury risk monitoring (0.8-1.3 = sweet spot) [Murray et al., 2017; Griffin et al., 2021; Gabbett, 2016] • Polarized Training Score — 0-100 measure of how closely your distribution matches your targets 3. Body's response: • Resting Heart Rate (RHR) — Calculated from your defined sleep window (adaptive percentile: 5th-15th) • Heart Rate Variability (HRV) — Daily RMSSD averages during sleep [Task Force, 1996; Plews et al., 2013; Buchheit, 2014] • EWMA trends — Exponentially weighted moving averages for both RHR and HRV (acute and chronic windows) • Combined interpretation — RHR ↓ + HRV ↑ = positive adaptation; RHR ↑ + HRV ↓ = possible fatigue Data Management: • CSV export/import • Complete backup/restore (db) • All data stays on your device — no accounts, no cloud uploads, no tracking Creative Use Cases: • Coach analyzing athletes — Import athlete exports, analyze charts, provide feedback • Research analysis — Export CSV files for custom analysis in R, Python, or spreadsheets • Switch between athletes — Use "Delete All Data" + CSV import to analyze multiple individuals Requirements: • Google Health Connect installed on your device • Heart rate (and HRV) data in Health Connect from your wearable device (Gadgetbridge, Garmin, Polar, Samsung, etc.) • Android 8.0 (API 26) or higher Note on PAI: Our PAI-esque implementation is NOT the official commercial PAI® algorithm (which is proprietary). It uses EWMA and scaled TRIMP values to provide a similar intensity-weighted weekly score. The 100 PAI target remains the evidence-based health outcome from the HUNT Study research.

PDF Inspector
APK
PDF Inspector opens a PDF and shows what is actually inside it. Like a browser's developer tools, it parses each page's content stream into a navigable tree of elements (text blocks, vector paths and images) so you can find any single element, select it on the page or in the tree, and edit it. Edits go to a saved copy; your original file is never touched. Highlights: * DevTools-style element tree: every page is parsed into a structured tree of text, path and image nodes, grouped the way the PDF draws them. Switch between friendly labels and the raw content-stream operators. * Two-way selection: tap an element on the page or tap its row in the tree, and the other side highlights to match, with a clear bordered outline on the canvas. * Edit in place: move and resize an element, recolor its fill or stroke (entered as hex, with the element's color space shown), and retype text. When the original font lacks a character, re-encode the line with a fallback font, bundled or taken from your device or imported. Changes are written straight back into the content stream, with full undo and redo. * Surgical delete: remove exactly the element you picked by rewriting just its part of the content stream, leaving the rest of the page untouched. * Save a copy: write your edited PDF to a new file through the system file picker; the source document is left unchanged. * Smooth viewing: pan and pinch-zoom, fit to width or height, a global zoom that carries across pages, and a full-screen mode. * Dockable inspector: the inspector panel docks to the side in landscape or the bottom in portrait, can be resized, and can be made transparent to see the page through it. * Material You: Material 3 design with dynamic color on Android 12+, light / dark / system themes and a choice of accent colors. Private and open: * Open source, no accounts, no telemetry. * No network access and no storage permission: files are opened and saved through Android's Storage Access Framework, so the app only ever touches the documents you explicitly pick. PDF Inspector works with the drawing primitives a PDF already contains: select, move, resize, recolor, retype and delete them. It is not a word-processor-style text editor, so lines do not reflow, but when the original font is missing a character you can re-encode the text with a fallback font, bundled or taken from your device or imported.
