Independent software studio
Most software wants
your attention.
Ours gives it back.
MekongApps is a small studio making calm, focused tools — no engagement traps, no dark patterns, no noise. Just apps that do their job and get out of your way.
What we make
Three apps. Each one kills a specific kind of noise.
SideArc — Chrome extension
80 tabs open, and you
still find everything.
Chrome turns a busy day into a row of unreadable favicons. SideArc puts your tabs in a readable vertical list, splits them into spaces for each project, and saves the rest into folders — so nothing important gets buried.
- Full tab titles, always readable
- A separate space for every project
- Saved folders you reopen in one click
- Pin what matters, hide the rest
Zen Social — iOS app
Keep the people.
Ditch the machine.
Instagram is built to keep you scrolling. Zen Social strips out the parts designed to hijack your attention — reels, suggested posts, explore-page garbage — and leaves you with the feed from people you actually chose to follow.
- Reels blocked before they load
- Suggested posts replaced with calm
- DMs, stories, and your real feed stay intact
- No tracking, no ads, no algorithm
Topnote — macOS app
Tiny notes.
Always one click away.
Topnote puts a fast scratchpad in your Mac notch or menu bar. Capture a thought, checklist, or link without opening a full notes app or losing your place.
- Lives in the notch or menu bar
- Fast notes, checklists, and links
- Works quietly over every app
- One-time purchase, no account needed
Topnote How we build
We make the kind of software we wanted to use.
Calm by default
No badges screaming for taps, no infinite feeds, no manufactured urgency. Our apps stay quiet until the moment you actually need them.
No dark patterns
Nothing engineered to trap you, upsell you, or quietly waste your time. If a feature only serves our metrics and not your day, it doesn't ship.
You're the user, not the product
No ad tracking, no selling your data, no algorithm deciding what you get to see. You're paying with money or nothing — never with your attention.

Bug reports, feature ideas, or just want to say something — we read everything and reply to most of it. A real person, usually within a day.
