Web · iOS (in browser) · Windows · macOS · Linux · Android

First-launch notes & iOS

macOS: pick the Apple Silicon (M1+) or Intel build above. It isn't notarized, so right-click the app → Open → Open the first time to get past Gatekeeper.

Windows (direct): an installable MSIX outside the Store — pick x64 for a regular PC, ARM for an ARM-based Windows PC (e.g. Surface Pro X). It's signed with our own certificate rather than a paid one, so Windows may block the install as untrusted; the Microsoft Store version above installs without that hassle.

Linux: a self-contained binary — chmod +x it, then run.

Android: one universal APK — works on Android 7.0+ (both older 32-bit and modern 64-bit devices), no need to pick a variant. Download it, then allow "install unknown apps" for your browser/file manager when prompted.

iOS: no App Store build needed — open the web version in Safari, then Share → Add to Home Screen to install it like an app.

Timezone Watch — live analog and digital clocks for cities around the world
Utilities

Timezone Watch

Live analog & digital clocks for any city — day/night at a glance, time-zone offsets, and your own saved list. Installs like a native app and works offline.

Web · Windows · macOS · Linux · iOS (sideload) · Android

First-launch notes & install as a web app

macOS: a universal build (Apple Silicon & Intel). It's ad-hoc signed rather than notarized, so right-click the app → Open → Open the first time to get past Gatekeeper.

Windows (direct): unsigned — no code-signing certificate, so SmartScreen may warn on first run. The Microsoft Store listing (coming soon) will install without that hassle.

Linux: an AppImage — chmod +x it, then run.

iOS (.ipa): not an App Store build — a sideloadable package signed with a free Apple developer identity via a tool like AltStore. Installs like a real app, but expires after about 7 days and needs re-signing to keep using — the simplest option is usually just installing the web version below instead.

Any platform, as a web app: open Timezone Watch in your browser, then use the browser's Install app option (desktop Chrome/Edge) or Share → Add to Home Screen (iOS/Android Safari/Chrome). Runs in its own window and works offline, no download required.

Microsoft Store: coming soon — the app is built as an installable PWA, ready for Store packaging.

Meet Zone — red, amber, and green meeting-time grid across timezones
Utilities

Meet Zone

Add everyone's timezone and instantly see red, amber, and green across every hour of the day — find a meeting time that actually works, without the mental math. Installs like a native app and works offline.

Web · Windows · macOS · Linux · iOS (installable)

Install as an app

Any platform, as a web app: open Meet Zone in your browser, then use the browser's Install app option (desktop Chrome/Edge) or Share → Add to Home Screen (iOS/Android Safari/Chrome). Runs in its own window and works offline, no download required.

Share a meeting: add your participants, tap Copy share link, and send it — whoever opens it sees the same grid without overwriting their own saved list.

macOS (direct download): Apple Silicon only, unsigned — right-click the app → Open → Open the first time to get past Gatekeeper.

Windows (direct): unsigned — no code-signing certificate, so SmartScreen may warn on first run.

Linux: an AppImage — chmod +x it, then run.

FlightDeck — live flight tracker on a real-time world map
Travel

FlightDeck

Track flights live on a real-time world map — status, gate, timeline, and telemetry, all in one place. Installs like a native app and works offline.

Web · Windows · macOS · Linux · Android · iOS (installable)

Install as an app

Windows / macOS / Linux (desktop Chrome or Edge): open FlightDeck, then click the install icon in the address bar (or menu → Install FlightDeck…). It runs in its own window and works offline.

Windows (sideload, no browser needed): download the ZIP above, unzip it, then right-click install.ps1 → Run with PowerShell. It trusts the package's certificate, installs the app, and launches it — no Store, no browser.

Android: open FlightDeck in Chrome, then menu → Add to Home screen / Install app.

iOS: open FlightDeck in Safari, then Share → Add to Home Screen.

Microsoft Store: the name is reserved and the install package is built — listing goes live once it's submitted and clears certification.

Doorstep — package tracker showing active parcels with carrier and delivery status
Package tracking

Doorstep

Paste a tracking number and Doorstep works out the carrier automatically, then keeps checking in the background — so you find out it's out for delivery from a notification, not by refreshing a carrier site.

About the studio

Solo Apps Studio is one developer, building complete software end to end — from the first line of code to the store listing or the enterprise pitch. That spans cozy consumer apps, arcade and narrative games, and AI-powered business software like ApprovalIQ. The goal is simple — small, polished, honest software, with no dark patterns and offline-friendly wherever it can be.

Some titles are still finding their final home. Apple builds ship as direct, self-signed installs for now (a paid Apple Developer account is on the roadmap), and a few games are mid-build. Everything here is made by hand.
