Encoders and decoders
Base64, URL, HTML entities, JWT inspection. Everything decoded in the page, never posted to a server.

01 / Everyday utilities
One screen, one answer
Converters, calculators, counters, formatters, document scanners, timers. A tool in this group should be usable within two seconds of the icon being tapped, with the thing you came for already on screen.
We spend most of the effort on the part nobody notices: the keyboard that opens with the right layout, the result you can copy with one tap, the last value still there when you come back tomorrow.
What this looks like in practice
- No splash screenThe app opens on the tool, with your last input kept.
- Copy in one tapEvery result is selectable and copyable without a menu.
- Small downloadWe draw interface elements in code and skip the asset packs.
Your records stay yours
- Stored on the deviceRoom, SQLite or a local file. No account needed to start.
- Export to JSON or CSVYou can take your history out at any time and read it in a spreadsheet.
- Import backAn export you cannot restore is a hostage, so we write both halves.
02 / Trackers and logs
Keep the record, keep the file
Habits, expenses, meter readings, workouts, inventory, maintenance. These apps live on trust, because you only find out whether the data was safe on the day you need it.
So we start from local storage and working export, then add syncing only when a person asks for it and understands what it means.
03 / Developer tools
Small helpers for people who build things
The toolkit on our home page is one of these. Short, local, and good enough that you stop keeping a tab open for it.
Formatters
JSON, XML, SQL. Pretty-print, minify, and point at the character where the parse broke.
BrowserRegex workbench
Pattern, sample text, live matches with group names, and an explanation of what each piece does.
BrowserDiff viewer
Side-by-side or inline, with whitespace handling you can switch off when it lies to you.
BrowserTime and ID tools
Unix timestamps, time zones, cron expressions in plain language, UUID and hash generation.
Browser · CLIBuild helpers
Scripts that strip unused permissions, check an AAB against its manifest, and report what shipped.

04 / Offline-first apps
Software for the train, the plane and the basement
A connection is a convenience that disappears exactly when you need it. We design the offline path first and treat the network as an improvement on top.
In practice that means the database is local, the interface never blocks on a request, and anything that failed to send is queued and retried without a dialog interrupting you.
Local database
Room with Kotlin, Hive or Drift with Flutter. Reads are instant because nothing is remote.
Queued writes
Changes made without a connection are kept and sent when one returns.
Honest state
The interface says what is saved locally and what has reached the server.
Working together
Two ways we take on outside work
Contract builds
You have a defined piece of software you want built on Android or the web. We agree the scope, the stack and the date, then build it. We prefer projects small enough to finish than ones large enough to drift.
Fixed scope · Fixed dateRescue work
An app got slow, grew to forty megabytes, or was rejected by a store and nobody is sure why. We audit it, write down what we find, and rebuild the parts that need it. Sometimes the answer is to delete features, and we will say so.
Audit · Report · RebuildTell us what you need built
A paragraph is enough to start. What it should do, who uses it, and when you need it.
