In short

Slash Digital Lab develops iOS and Android apps from Bogotá, and a production app is more than a companion: onboarding, notifications, offline, analytics and a release cycle. We publish to the App Store and Google Play and keep the app alive with your team.

Evidence: the official app of Colombia Tech Fest and the full Flutter app for Réseau Mazette (iOS and Android). For AI on the phone itself: small models on device. The rest of the product: digital products and web applications.

What we deliver

What a Slash app includes

We choose the stack by the case: Flutter when it sustains the product, native when the device demands it.

01

Cross-platform Flutter

One codebase, two stores; native-grade performance for community products.

02

Native when it matters

Native iOS/Android for advanced capabilities: camera, sensors, payments.

03

Embedded AI

Copilots, recommendation and moderation inside the app.

04

Stores & releases

Publishing, versioning, review cycles and an update plan.

How we work

From idea to the stores

  1. Discovery

    Users, use cases and store constraints, defined in writing.

  2. Prototype

    The flow tested with real users before building everything.

  3. Build & beta

    Sprints with TestFlight and Play Console internal testing.

  4. Launch

    Publication, analytics, notifications and a release plan.

Frequently asked questions

The questions we hear often

Native or cross-platform?

By case: Flutter for community products with sustainable budgets, native for specific capabilities.

Do you publish to the stores for us?

Yes: listings, screenshots and the review process included.

PWA instead of an app?

When the case allows it (see Peoplesnap); a web app skips stores entirely.

Post-launch support?

Yes: two months of support included after delivery; after that, releases, hotfixes and a priority-driven roadmap on the support plan you choose.

Notifications and chat?

Yes: segmented push and messaging, as in the Tech Week app.

How long does store publishing take?

Leave weeks, not days. Apple says it reviews most submissions in under 48 hours, but on Google Play a personal developer account created after November 13, 2023 first needs a closed test with at least 12 testers for at least 14 days.

How do users get in, and what happens to their data?

Through controlled access. In the Colombia Tech Fest app, every account starts from an invitation code and the guest accepts the privacy policy; in Réseau Mazette, members sign in with their website credentials. If the app lets people create accounts, it must let them delete them in the app: Apple and Google Play require it.

How long does it take to build an app?

It starts with a two-week discovery that sets the scope; then we work in two-week sprints with a demo, so you see the app grow on your phone. Add store review time and, after delivery, two months of included support.
