AMSS
Acute Mountain Sickness Score — right in your pocket
AMSS is a practical digital companion to the 2018 Lake Louise Acute Mountain Sickness Score (AMSS) Questionnaire (NCBI reference). Acute mountain sickness (AMS) is a syndrome affecting non-acclimatised individuals who ascend to high altitudes, typically above 2,500 metres, caused by decreased atmospheric oxygen partial pressure inducing hypoxia. AMSS puts the validated clinical tool at your fingertips — whether you are a hiker, mountaineer, expedition medic, or wilderness guide.
- Based on the validated 2018 Lake Louise AMS Score framework
- App settings persist across sessions for uninterrupted use
- All data processed and stored locally — nothing leaves your device
- No account, no tracking, no advertisements
Upa Intervals
Sequence training timer for sports, yoga & wellness
Upa Intervals is a fully customisable interval timer built for sequence training across sports and wellness disciplines — including yoga, rehabilitation, and meditation. It serves as a companion to an upstream app, scheduled for release in late 2026. Activities labelled "Rest" are highlighted in a distinctive red colour so you never lose your place in a sequence. A built-in metronome that runs at 50 bpm supports rhythmic, mindful practice.
- Create and edit unlimited custom activity sequences
- Rest activities highlighted in red for instant visual cue
- Export & import sequences to share with other users
- Mattro metronome at 50 bpm (1.2 s intervals ≈ 1 mātrā)
- Automatic backup of application settings across sessions
- No data collected or transmitted — fully offline
Pubbr
The EPUB reader Android deserved — with real JavaScript support
In the digital age, an increasing number of educational resources are published in the universal EPUB-3 format, taking advantage of the interactivity that JavaScript enables. On Android, however, most EPUB readers offer minimal JavaScript support — leaving interactive textbooks, simulations, and educational tools inaccessible on mobile. Pubbr was built specifically to fill that gap. Its intentionally clean and minimalist interface keeps the focus on the content, while under the hood it handles a wide range of JavaScript features that bring EPUB-3 documents fully to life.
- Extensive JavaScript support for interactive EPUB-3 documents
- Open .epub files directly from your file manager
- Keyword search, bookmarks, themes, and font-size adjustment
- Bundled Demo.epub showcasing JS capabilities
- External links disabled by design for security
- Open source sample EPUB documents — available on GitHub (lavrentius-dev/pubbr)
Poteca
The resync of Dynamic Signaling Maps™ — on Android
Poteca is an app inspired by a remarkable chapter in the history of bioinformatics. In the early 2000s, a web-based software called Dynamic Signaling Maps (DSM) was developed by Hippron Physiomics Inc. for the dynamic visualization and analysis of biological cell signaling pathways. DSM used 3D layered directed graphs to visualize complex biological networks, and was cited in scholarly work alongside databases such as KEGG and BioCarta. Now, the core functionality of this application is available as a native Android app, under the name Poteca.
- DSML Syntax Checker — validates custom signaling pathway events encoded in the symbolic language DSML, covering five fundamental classes of signaling events
- SigMap Converter — processes DSML documents via a custom layered graphics engine, producing editable and scalable vector pathway maps
