HeyFolks! detects a handheld that was forgotten in the dark or left idle, and sounds an alarm so the operator can retrieve it. While another HeyFolks! device is nearby, the alarm stays quiet.
Free trial version: 1.12.38 · Android 8.0 or later
A simple sequence, checked again every time the handheld is idle.
After the screen has been off for a set time, HeyFolks! starts checking the environment.
If the ambient light stays below the threshold for several readings in a row, the device is probably inside a pallet sleeve or a closed place.
The app looks for another HeyFolks! device nearby by Bluetooth Low Energy and/or sound, for a set search window.
If a neighbor is found, the device waits and searches again. If none is found, the alarm sounds with vibration until the operator picks the device up.
Teams that depend on handhelds every shift, and anyone who has already lost a phone.
Warehouses, distribution centers, cross-docking hubs and third-party logistics (3PL) operations move handhelds through picking, put-away, receiving, dock, yard and returns (reverse logistics). A device left in a pallet sleeve, a returns cage or a dock lane means lost productivity, inventory discrepancies and SLA breaches. HeyFolks! sounds an alarm when a handheld sits idle at those points, so it is found before it causes a discrepancy, an SLA breach or a shipping mistake.
If you have ever lost a phone on a bus, in a taxi or in a drawer at the office, you know the cost: lost contacts and data, locked accounts and hours spent looking for it. HeyFolks! is made for that moment. When the device is left behind in the dark, the alarm sounds until someone picks it up, so you do not have to go through that again.
Everything the app does, and the settings you can change on each device.
Reads the ambient light sensor and triggers the search when the light falls below the threshold for a set number of readings. Threshold, reading interval and screen-off time are all configurable.
Each device advertises an identifier and looks for the others. You set the signal strength (dBm) that counts as nearby, how long a sighting stays valid, the scan mode and the advertising power. A live list shows which devices are seen as neighbors.
As an alternative to Bluetooth, each device plays a short tone sequence and listens for others at a configurable frequency and volume.
Detects a handheld that stays with the screen on, dark and without movement for a set number of minutes. The accelerometer defines what counts as still. Movement stops this alarm.
Uses the accelerometer to detect a fall (free fall followed by impact, or impact only). The threshold can be calibrated with a simulated fall. Optionally, the alarm can only be stopped with a PIN.
If the device has no light sensor, the app says so and uses only the idle time with the screen locked as the trigger. The time is configurable, so long idle periods can be allowed.
Pick one or more alarm sounds, or add your own audio files. The alarm can sound at maximum volume and vibrate, and you can turn the sound off and keep only the vibration.
A permissions screen shows what is OK and what is missing: battery optimization, Bluetooth, location for BLE, microphone, notifications and the light sensor. It also shows live charts for light, microphone and movement, with minimum, maximum and average values.
Every event is recorded in a CSV file on the device: alarms, searches, neighbors found, screen changes and status. You can view a summary in the app and share the file. The file is capped at 50 MB; when it is full, the oldest lines are removed.
The app is available in English, Portuguese and Spanish, and the language can be changed in the settings.
