Engineering Process

How we engineered
Guardian Bubble

A complex safety system reduced to a calm, elegant experience - built in 14 weeks using Ailoitte's AI Velocity Pod methodology.

Discovery & Safety Architecture

We mapped every edge case in child safety - geofencing logic, SOS escalation trees, data privacy for minors. COPPA and GDPR compliance was baked in from day one, not bolted on.

Real-Time Location Engine

Built a WebSocket-driven GPS pipeline with sub-3-second latency. Smart battery optimisation keeps location active without draining the child's device - a key parent complaint with competing apps.

AI Predictive Safety Layer

Trained a behavioural model on anonymised usage patterns to flag anomalies - unusual routes, sudden stops, extended time in unrecognised zones - before parents need to ask.

SOS & Emergency Protocol

Engineered a multi-channel SOS - push, SMS, ambient audio capture - that triggers in 2.4 seconds and routes to all linked guardians simultaneously with live location.

Dual-App Experience Design

Two distinct apps: a friendly, mascot-driven child interface that feels like a companion, and a calm, information-dense parent dashboard that surfaces the right data at the right moment.

Core Features

Three pillars.
One seamless platform.

Always-on location,
zero anxiety.

Real-time GPS with geofenced safe zones - parents get instant arrival alerts when their child reaches school, home, or any custom location. No manual check-ins needed.

Sub-3s location updates via WebSocket - not the 30-second polling used by most competitors

Unlimited custom safe zones - school, grandparents, friend's house - each with its own alert rules

Battery-smart tracking - adaptive polling intervals reduce child's device drain by 60% vs always-on GPS

Location history timeline with full route replay - always know where your child was, not just where they are

to parents and investors.

14wks

Zero to live on both stores

From initial discovery session to App Store and Google Play approval - using Ailoitte's AI Velocity Pod methodology to compress a typical 9-month build.

2.4s

End-to-end SOS response

Time from a child pressing SOS to all linked guardians receiving a push alert with live location - across 3G, 4G, and WiFi networks in testing.

98%

GPS accuracy in urban testing

Validated across 6 cities with varied building density. Adaptive precision mode maintains accuracy in underground car parks and dense urban corridors.

50k+

Families on platform at launch

Grew to 50,000 active families within the first 90 days - driven by organic referral loops and strong App Store ratings averaging 4.8 stars.

60%

Reduction in battery drain

Our adaptive GPS polling engine consumes significantly less power than always-on competitors - a key differentiator in app store reviews.

4.8★

Average store rating

Consistently rated 4.8 across iOS and Android. Top reviews cite the SOS response speed, clean UI, and reliability as primary reasons for recommending to other parents.

Client Voice

“We came to Ailoitte with a complex brief - real-time safety, AI behaviour prediction, and a consumer-grade UX that parents would actually trust. They delivered all three, in 14 weeks, on budget.”
