The collection

Four products, one workshop.

01 / 04

The main project Android

IronPulse

A workout logger that keeps the numbers straight.

A dark-themed workout logger for strength training and calisthenics, built for the gym: offline by default, no account, no tracking, and a 1,333-movement catalogue whose animations stream on demand instead of being shipped inside the APK.

  • 1,333 exercises with streamed animations
  • A routine is a whole week, not a list
  • Autosaved sessions that survive a crash
  • Volume, estimated 1RM and weigh-in analytics
  • Optional AI coach with your own key

Project 02 Android

Calculator Suite

Sixty-six calculators, one Android app.

A fast everyday keypad, a full calculus workbench, an electrical circuit editor that works out the circuits you draw, and an AI that reads a photograph of a problem. Every tool computes for real and shows its working rather than a bare number.

  • 66 tools across algebra, calculus, finance and more
  • A calculus workbench with 14 focused tools
  • An electrical circuit editor that solves what you draw
  • Exact arithmetic, with numerical answers marked ≈
  • Works with the network off

Project 03 Android

Discount Hunter

Every game discount from Steam, GOG and Epic in one feed.

A native Android app that pulls live discounts from the Steam Store, GOG and the Epic Games Store, merges them into a single daily feed, and lets you save games so you hear about them when the price drops.

  • Three stores merged into one daily feed
  • One deduplicated result per game when you search
  • Prices converted honestly, never just relabelled
  • Deal alerts that arrive with the app closed
  • A “Where to buy” comparison on every game

Project 04 Windows

CodeScope

A native Windows front end for the scc engine.

A native Windows desktop application that analyses a codebase with the pinned, frozen scc engine and presents the result either as a rich in-app dashboard or as scc’s own self-contained HTML infographic. It never makes a network request.

  • Metric cards, language breakdown and a per-file table
  • Hotspots, coupling, authors and bus factor from real Git history
  • Every optional report section has a switch that works
  • One self-contained HTML file to export
  • The last thirty runs, reopenable without re-running the engine

About

One developer, four applications, no company behind them.

JuggyBob is the name I build and ship under. Everything on this site is independent software I design, implement, test and release myself — Android applications written in Kotlin with Jetpack Compose, and a native Windows desktop tool written in WPF on .NET.

The apps share a set of values, because I wanted them for myself first: they work without an account, they work without a network, they do not carry analytics or advertising, and the data you put into them stays on your device. Where a feature genuinely needs the internet — live store prices, exchange rates, an AI provider — it is opt-in, and the app says plainly what it sends.

The source code for all four is public, issues and pull requests are welcome, and every release ships with a checksum so you can verify what you downloaded.

Method I design the architecture, write the specifications and domain models, do the API and prompt-engineering work and run the testing and quality assurance — and the code itself is written with AI assistant workflows. It is worth knowing before you read the source.
