AppJuice · Native App Development Studio
We build apps
that make a difference.
From enterprise SaaS to polished consumer apps — clean code, thoughtful design, zero compromises.
upstream
The native FTP, FTPS & SFTP client for macOS. FileZilla's power, Apple's elegance.
Pay once, no subscription — built in Swift & SwiftNIO.
Dual-Pane Workflow
Browse your disk and your server side by side, with native icons, breadcrumbs and drag & drop from Finder.
Unstoppable Queue
Concurrent, recursive transfers that resume automatically after interruptions — all powered by SwiftNIO.
Live Remote Editing
Open remote files in VS Code, TextMate or Xcode — Upstream re-uploads instantly on every save.
Secure by Design
Credentials stay in the macOS Keychain, inside the App Sandbox. Nothing ever leaves your Mac in the clear.
inkiostro
The distraction-free Markdown editor for Mac, iPad & iPhone. Write plainly, preview instantly, export anywhere.
Free to download, private by design — no account, no tracking.
A clean page
No toolbars in the way. Careful typography, room to breathe, and nothing between you and the words.
Live preview
See the formatted result as you type, side by side with the text. What you write is what you get.
iCloud sync
Start a note on your iPhone and finish it on your Mac. Your documents follow you, with no account to create.
Export anywhere
PDF, HTML and EPUB in a tap — plus LaTeX math with KaTeX and Mermaid diagrams, rendered properly.
group sms
Send one message to a whole group or list, from your own phone and your own plan. No gateway, no per-message cost.
Your contacts never leave your device.
Groups & lists
Use your phone's contact groups or keep separate distribution lists, imported straight from a CSV.
Personalised
Save the messages you send often and drop each contact's own name into them, so 200 people get 200 personal texts.
Campaigns & scheduling
Plan a send for later or spread thousands of contacts across days, in daily batches your carrier won't throttle.
Private by design
No server in the middle. Groups, lists and contacts stay on the phone — nothing is uploaded anywhere.
Turn a walk into a friendly race: step challenges with live rankings, synced from Apple Health and Google Fit. In development.
Smart employee attendance tracking from any device. In public beta, free to use.
