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 AppShift Calendar
Pick your rotation once (3×12, 24/48, Kelly, DuPont, Pitman) and see every shift a year ahead.
iOS AppPunch Clock
One-tap punch in and out by project, with eight clock faces and a Lock Screen timer.
iOS AppWaqt
Locks the apps you choose when a prayer window is about to close, until you’ve prayed.
iOS AppBab Amanah
Saves the gate you came in by at Masjid al-Haram or Masjid an-Nabawi and walks you back to it, offline.
iOS AppShrunk
Scan a grocery barcode to see documented package-size changes and the unit price at your Kroger-family store.
iOS AppDupelganger
Finds duplicate photos, videos and documents; you pick what stays and confirm every removal.
iOS AppAutoCal
Point your camera at a menu and get three ranked picks for your calorie and protein targets.
iOS AppSpacePings
Buzzes a few minutes before the space station passes over you, then points you at it.
iOS AppRateRadar
Scores today’s exchange rate 0–100 against the last 90 days, so you know when to change money.
