A family activity app
Kids log reading, math practice and workouts, earn points and trade them for rewards their parents approve. For iPhone and Android.
Websites and apps for small and medium businesses
We build the websites and apps small businesses run on.
Northline Studio LLC is a software studio in Pittsburgh. We design, build and support websites, web apps and mobile apps for small and medium businesses, and we run apps of our own.
What we build
Four kinds of work, each built to be maintained after launch.
Websites
A fast, clear site that explains what you do and makes it easy to reach you. Your team can update the text and photos without calling us.
For Company sites, service pages, menus and price lists
Web apps and portals
Browser-based tools for your customers or your staff: booking, orders, quotes, client portals and internal dashboards.
Replaces A shared spreadsheet, a paper form or an inbox full of requests
Mobile apps
iPhone and Android apps from one codebase. We take them through App Store and Google Play review and publish them under your company's own store accounts.
For Customer apps, loyalty and ordering, field and staff tools
Support after launch
Fixes, updates for new phone and browser versions, and the yearly changes Apple and Google require to keep an app in their stores.
For Sites and apps we built, and ones we take over
How a project runs
A written plan first, then working software in small steps.
Scope
We write down what the software must do, what's included and what isn't, and the cost and dates. Nothing gets built until you approve it.
Build
The work happens in small pieces. You see each piece working before the next one starts.
Check
Every change is reviewed and tested before it reaches your customers.
Launch
We publish the site or app, hand over the accounts and logins, and stay on for fixes.
Our own apps
We build and run products of our own.
Running our own apps keeps us honest about what software takes to maintain. Two are in development now.
Bookkeeping for online resellers
Pulls in sales from the places a reseller sells and shows the true profit on each item after fees, shipping and sales tax.
How we handle data
The same rules for our apps and yours.
No ads, no tracking tools
Our apps show no ads and send nothing to analytics or advertising companies. This website doesn't use cookies or tracking either.
Only what the software needs
We collect the minimum information each feature needs. Apps used by children are designed around U.S. children's privacy law (COPPA).
Your accounts stay yours
Client domains, hosting and app store accounts are set up in your company's name, so you're never locked in to us.
