We build products
people actually use.
Stack Curious is a product studio with 24 products live: 4 web apps and 20 iPhone apps on the App Store.
Featured
Three web apps we build and run: for security gates, for studying, and for bookkeeping.
GateLog
gateloghq.com
Manned access control for any guarded post: gate, lobby, reception or loading bay. The guard taps entries on a tablet instead of writing in a book, and it logs without a network. Head office sees every post live, and every entry stays searchable.
Klarrity
klarrity.app
A Chrome extension that turns a web page, a PDF or a YouTube clip into flashcards. It writes only the cards you still need, and can quiz you first so the deck covers what you missed. Free every day, with export to Anki, CSV or the clipboard.
StatementVision
statementvision.com
Converts bank CSV and PDF statements into QBO, OFX, QIF, IIF or CSV for QuickBooks and other ledgers. CSV files convert entirely in your browser and are never uploaded; PDF statements are read by AI in memory and never stored. Free preview, no account, no subscription.
iPhone apps
A selection of the 20 iPhone apps we’ve designed, built, and shipped.
iOS AppPunch Clock
One-tap punch in and out by project, with eight clock faces and a Lock Screen timer.
iOS AppShift Calendar
Pick your rotation once (3×12, 24/48, Kelly, DuPont, Pitman) and see every shift a year ahead.
iOS AppExpiro
Every iqama, Emirates ID, visa and passport in the household on one Hijri and Gregorian renewal calendar.
iOS AppDupelganger
Finds duplicate photos, videos and documents; you pick what stays and confirm every removal.
iOS AppWaqt
Locks the apps you choose when a prayer window is about to close, until you’ve prayed.
iOS AppNomadFit
See today’s workouts, run clubs and drop-in gyms in whichever of 50+ cities you just landed in.
