02 Featured work

Built, shipped and out in the wild.

We designed, built and publish the TraiLink app, the companion to TraiLink's off-grid group trackers.

Your whole crew on one live map, with no cell service.

TraiLink trackers form their own off-grid network. Our app pairs with each device over Bluetooth to put everyone's live position, trails and messages on one map, even where the cell service ends.

  • Live mappingPositions every 2 seconds, with breadcrumb trails
  • Offline mapsSatellite and topo tiles, KML/KMZ overlays

03 Why us

How we do it

Innovative strategies

Gain a technical advantage

We apply the latest technologies in ways that fit each project. You're never limited by our comfort zone: we push the boundaries as far as it takes to reach the goal.

Strategic insights

Results-oriented solutions

We learn something on every project, and that experience lets us predict and measure the outcome of our solutions before you commit to them.

Uniquely tailored

From science to art

We treat every project as a work of art. The paint may be the same, but the result is always unique. No cookie-cutter solutions just to save time.

04 Process

From idea to launch, in the open.

Clear steps, frequent demos and no surprises. You'll always know where your project stands.

  1. Discover

    We dig into the problem, the people and the goal, then agree on scope, budget and what success looks like.

  2. Prototype

    A clickable design or working proof of concept, fast, so you can test the idea before committing to the full build.

  3. Build

    Short iterations with regular demos. You see real progress every step of the way, not just at the end.

  4. Launch & grow

    We take care of the App Store, Google Play and hosting, then keep improving based on real-world use.

05 About us

Passionate. Agile. Experienced.

We are the decisive factor behind your success.

Our team brings deep experience to every project we touch. We have built robots from the ground up and software infrastructure for hospitals. We founded AppPlusPlus to bring our combined skills together and do what we love: build creative solutions without limits.

We're the kind of people who stay up all night to solve a problem, the ones you'd find in the garage or the lab tinkering just for fun. We'll get your project done right, and love doing it.
