We continually sharpen our skills and ensure that we stay abreast with the latest technologies. .
Hi, we’re Rietek (pronounced “ree-tech”). The name comes from our Dutch family name “van Riet” + “tek” — because family heritage matters to us, even in technology.
With over 30 years combined experience in project management, telecommunications, geographic information systems (GIS), web development, and now mobile apps with Flutter, we bring big-company expertise with small-team heart.
Every line of code, every pixel, and every submission to the App Store or Google Play is handled personally by us — no outsourcing, no middlemen.
One codebase, native speed and feel on both iOS and Android. Proven with FullAlert — live on both stores.
Clean, intuitive interfaces that users love. We design with your users (and App Store guidelines) in mind from day one.
Real-time tracking, geocoding, geofencing, safe zones — exactly what we built into FullAlert and can build for you.
End-to-end encryption, secure authentication, privacy by design — because some apps (like family safety) can’t afford shortcuts.
When real lives depend on your app (like they do with FullAlert), security isn’t a feature — it’s everything. We implement industry-best practices from day one: encrypted Firebase/Realtime DB, secure auth (Apple/Google/Biometrics), offline-first design, and regular penetration testing.
Firebase, AWS, custom Linux VMs, real-time databases — scalable and rock-solid from the start.
We write your store listings, create screenshots, handle reviews and get your app approved fast — just like we did with FullAlert.
We didn’t just build FullAlert for the stores — we built it for our own families first. That same care goes into every client project.
See where your loved ones are at any moment with accurate, battery-friendly tracking.
One tap sends instant alerts with location to all emergency contacts.
Get notified the moment someone arrives at or leaves school, home, or work.
AI-powered driving insights—all in one modern, privacy-conscious app.
Automatic alert if the phone detects a possible vehicle collision.
Invite only the people you trust — end-to-end encrypted and no data selling, ever.
We work with fixed-price quotes for most projects (from R150 000 / ~$8 500 USD upwards) or time & material for evolving ideas. Every quote is tailored — contact us for yours.
A typical MVP (like the first version of FullAlert) takes 3–5 months from start to live stores. Complex apps with GIS or real-time features: 5–9 months.
No! FullAlert is our last, but we love consumer apps, enterprise tools, IoT companions, GIS solutions — anything that needs to be fast, beautiful, and reliable.
Absolutely. Your idea stays 100% confidential.
Yes — we offer monthly retainers or ad-hoc support. FullAlert itself is still updated every 2–3 weeks.
We’ve done it many times (including FullAlert). We handle everything: listings, screenshots, keywords, review responses, and compliance.
You talk directly to the people building your app, pay far less overhead, and get senior-level expertise on every line of code. Plus we actually care — your success is our reputation.

“FullAlert has already given me peace of mind I didn’t know I needed. My teenage daughter walks home from school and I can see the moment she arrives safely — every single day. Thank you Rietek for building something you clearly use yourselves.”
“As a single dad with shared custody, knowing exactly when my son leaves his mom’s house and arrives home has removed so much stress. The app is simple and just works.”
