You get a clickable prototype on your phone after three two-week sprints. Change anything before we start the next sprint, no extra cost. Most agencies bill by the hour for revisions; we bake two free rounds into the fixed price.
We host the backend on your AWS account so you own the infrastructure from day one. One client in San Andreas was shocked when their old vendor charged $0.03 per API call; our client pays only for AWS compute, about $14 per month for 5,000 daily users.
Altaville’s mountain roads lose signal. Our apps keep working when the network drops, syncing automatically once you’re back in range. A client running a tree farm cut their daily reconciliation time from 90 minutes to 12 minutes because the app stored every transaction locally.
Flutter lets us ship to both app stores from the same Dart code. When Apple changed the in-app purchase rules in March 2024, we updated the shared code once and released to both stores the same day. No separate iOS and Android teams means lower risk and faster fixes.
A clear process, no surprises.
We spend the first week on the ground (remotely) with the people who will use the app. For a Murphys boutique, that meant standing behind the counter during a Friday night rush to see how clerks switched between inventory, booking, and a paper loyalty card. The insight became the app’s first screen: a single swipe between product lookup and customer history.
Before we write code, we sketch every screen on paper and test it with sticky notes. A client in Avery who runs a Christmas tree lot needed to see the inventory count drop as a sale was entered. We built a physical slider with post-it notes so the owner could feel the interaction before we touched a computer.
We build the Dart frontend and Firebase backend in parallel. While the India team writes the sync logic, our QA engineer tests on an iPhone 13 in airplane mode to simulate the spotty Wi-Fi on the way to the wineries. Every build is pushed to TestFlight and Google Play Beta the same day.
We hand the app to a small group of power users, usually 10% of the full user base, and watch the crash reports roll in. A client in Arnold’s restaurant ran the beta for two weeks during brunch shifts; we fixed three bugs before the public launch and improved the table-selection algorithm based on real reservation patterns.
After launch, we switch to a monthly retainer for fixes and minor features. One client in Copperopolis asked for a new loyalty tier six weeks after launch; we delivered the update in two weeks because the codebase was already theirs. No extra licensing, no vendor lock-in.
