Hank
Tech Partnership
Consumer IoT / BLE Tracking
6 Months
- Tag finds phone, phone finds tag
- Multi-item tracking dashboard
- One-button pairing with BLE Low Energy
Key Outcomes
Delivered a consumer-grade BLE tracking tag with bidirectional functionality — the tag locates the phone and the phone locates the tag — in a compact, keyring-attachable form factor
Built native iOS and Android companion apps with one-button pairing, multi-item dashboard, and audible alert triggering even when the phone is on silent
Launched in Nigeria and Australia markets with localized e-commerce distribution and sub-$20 price positioning
The Challenge
Before partnering with Iottive, Hank was facing several issues:
Bidirectional Communication Complexity
Most Bluetooth trackers only work one way — phone finds tag. Hank required reverse functionality where pressing the tag button triggers an audible alert on the phone, even if the phone is on silent mode, demanding deep OS-level integration on both iOS and Android.
Cost-Sensitive Market Positioning
Targeting emerging markets like Nigeria required a retail price under $20 (approximately ₦14,800), constraining component selection, PCB complexity, and manufacturing processes while maintaining reliable BLE range and battery life.
Multi-Item Management UX
Users tracking keys, wallet, bag, and pet need a dashboard that makes it immediately obvious which item is nearby and which is out of range — without requiring technical understanding of Bluetooth signal strength or connection states.
Cross-Platform Parity
iOS and Android handle BLE background processes differently. Maintaining consistent location tracking,alert delivery, and tag communication across both platforms required platform-specific engineering with a unified user experience.
Our Solution
Iottive delivered a complete AIoT solution under a full-cycle product development model.
Bluetooth/IoT Expertise
Implemented bidirectional BLE communication where the tag advertises its presence to the phone and the phone can trigger the tag’s speaker, while the tag can independently command the phone to ring at maximum volume regardless of silent mode settings.
Design Thinking Approach
Designed the app for users with varying technical literacy, common in the target emerging markets. One-button pairing eliminates Bluetooth settings navigation. The item dashboard uses color-coded proximity indicators (green/yellow/red) instead of signal strength numbers.
Project Planning & Execution
Compressed development to meet seasonal e-commerce launch windows in both Nigeria and Australia. Parallel firmware and app development streams converged in a two-week integration and testing phase.
Functionalities Delivered
One-tap pairing, bidirectional ring (phone finds tag and tag finds phone), multi-item dashboard with proximity indicators, last-known-location map view, separation alerts, silent-mode override on phone ring, and shareable item links for family members.
Implementation Highlights
Sensors & Hardware
BLE SoC with integrated antenna in a compact keyring-attachable housing. Coin-cell battery (CR2032) with 6–12 month life depending on alert frequency. Waterproof to IPX4 for rain exposure.
Edge & Connectivity
BLE advertising with optimized intervals — fast advertising (100ms) when actively searching, slow advertising (1s) when idle — extending battery life 3x compared to constant-rate competitors.
Firmware & Performance Optimization
Tag firmware runs a minimal RTOS kernel consuming <10μA in idle state. Button-press detection uses hardware interrupt rather than polling, eliminating unnecessary wake cycles.
Data Analytics & Visualization
App-side signal strength averaging and Kalman filtering provide smoother proximity estimates than raw RSSI values, reducing false separation alerts in noisy RF environments.
Dashboard & UX
Clean card-based interface showing each tracked item with name, icon, proximity status, and last-seen timestamp. Map integration displays last known GPS coordinates when the item goes out of range.
Security & Compliance
BLE pairing with bonding prevents tag hijacking. User data stored locally on-device with optional cloud backup. Compliant with Australian consumer electronics regulations and Nigerian import requirements.
Results & Impact
- Successfully launched in Nigeria and Australia e-commerce channels within the target price range
- Bidirectional find-my functionality differentiated Hank from lower-cost one-way-only trackers in the market
- One-button pairing achieved >95% first-attempt success rate in user testing across both iOS and Android
- Battery life exceeded 8 months average in real-world usage through adaptive advertising intervals
- Multi-item support enabled users to track an average of 3.2 items per account
“We needed a Bluetooth tracker that worked both ways — not just the phone finding the tag, but the tag finding the phone, even on silent. Iottive’s firmware team solved the silent-mode override on both iOS and Android, which was the feature our customers asked for most. The onebutton pairing was critical for our market — our users don’t want to navigate Bluetooth settings menus.”

Lessons & Best Practices
Design for the Least Technical User
In emerging markets, many users interact with Bluetooth for the first time through a product like Hank.One-button pairing and visual proximity indicators eliminated every technical barrier identified in user testing.
Optimize Advertising Intervals Aggressively
Switching from constant 100ms advertising to adaptive intervals (100ms when searching, 1s when idle) tripled battery life without perceptible impact on discovery speed.
Test Silent-Mode Override Across OS Versions
iOS and Android handle audio override permissions differently across versions. Regression testing across 15 OS versions was necessary to maintain the ring-on-silent feature reliably.
Localize for Each Market
Nigeria and Australia have different e-commerce expectations, currency displays, and customer support patterns. Market-specific onboarding flows improved activation rates.
