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.
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.
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.
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.
Topnote Got a question?
Just email us.
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.
