About this app

SafeDriveBD is a smart driving assistant for Android phones, tablets and compatible Android car players. It works alongside navigation apps and adds road alerts, GPS speed awareness, OBD-II vehicle data, driving score, voice assistance, trip information and SOS support.

YOUR ROAD, YOUR ALERTS

No alert database can know every dangerous point on your daily route. SafeDriveBD lets you create your own alert zones for:

• School zones
• Sharp turns and accident-risk points
• Road work and narrow bridges
• Toll plazas and no-horn zones
• User-added speed camera points
• Rail crossings and other road hazards

Create an alert using your current location or enter latitude and longitude manually. Direction-aware filtering helps warn you as you approach the point.

Custom alert zones are stored locally on your device.

SPEED AWARENESS

• Live GPS speed display
• Voice and on-screen speed warnings
• Speed difference monitoring with OBD-II
• Highway and expressway driving support
• No Limit mode for open-road driving

OBD-II VEHICLE MONITORING

Connect a supported Bluetooth Classic ELM327 or KW902-compatible OBD-II adapter to view useful live vehicle data.

Depending on vehicle and adapter compatibility, data may include:

• Engine RPM and OBD speed
• Coolant temperature
• Throttle position and engine load
• Intake air temperature and MAF
• Fuel-related data where supported
• Vehicle/battery voltage

SafeDriveBD can warn about high coolant temperature and low vehicle voltage and includes OBD connection diagnostics and logging.

LIVE SAFETY DASHBOARD

View key information together:

• GPS speed and OBD speed
• SPEED DIFF
• Coolant status
• Vehicle voltage
• OBD connection status
• SOS and Voice status

DRIVING SCORE & REWARDS

SafeDriveBD analyses each trip using real driving conditions. Scoring can consider smooth acceleration and braking, traffic conditions, city or highway driving and driving consistency.

Track your R-Score, safe-driving points, badges and trip history over time.

SOS & ACCIDENT ASSISTANCE — BETA

SafeDriveBD can use phone sensors and driving information to identify unusual events such as heavy shock, sudden stop, sudden direction change or possible rollover/collision conditions.

A countdown gives you time to cancel an accidental SOS activation. If not cancelled, SafeDriveBD can help contact a trusted person and share your location.

Accident Detection is a sensor-based beta assistance feature. It does not guarantee crash detection and is not a substitute for emergency services.

VOICE ASSISTANCE

Supported voice commands allow hands-free interaction while driving. Spoken alerts can provide speed, road-zone, vehicle-condition and reminder information.

TRIP RECORD

Review trip time, distance, average speed, maximum speed and a shareable trip report.

VEHICLE CARE & SAFETY REMINDERS

Helpful reminders may include:

• Headlight and door-lock reminders
• Coolant and tyre-pressure checks
• Wheel-nut checks
• Engine oil, steering oil and brake-fluid reminders
• Vehicle battery and coolant warnings

BUILT FOR DIFFERENT VEHICLES

Driving modes support cars, motorcycles, pickups, microbuses and vans. Bike Mode includes rider-focused reminders such as helmet awareness and applicable road restrictions.

DESIGNED FOR PHONES & ANDROID CAR PLAYERS

SafeDriveBD adapts to regular Android phones and compatible larger Android car-player or head-unit displays. Split-screen support and the SDB floating button help keep important information accessible alongside your navigation app.

IMPORTANT

SafeDriveBD is a driving assistance tool. It does not replace official road signs, traffic laws, emergency services or your own safe-driving judgement. OBD-II features require a compatible adapter, sold separately. Feature availability may depend on device, vehicle, Android version and permissions.
