User guide
How to use FightNode
Use this guide to set up the BagNode sensor, connect it to the FightNode app, start a training session, record video, use heart rate, save history, compare rankings, and manage your profile and settings.
Before you start
Check first
Charge or power the BagNode sensor, enable Bluetooth on your phone, and keep the phone close to the bag during setup.
First setup
Install FightNode
Open the app page, install FightNode on Android, and allow Bluetooth permissions when the phone asks.
Turn on BagNode
Power on the BagNode sensor and make sure it is mounted firmly on the punching bag before connecting.
Scan and connect
Open FightNode, scan for Bluetooth devices, select your BagNode sensor, and wait until the app shows it is connected.
Start a round
Choose your training mode, start the timer, and begin punching after the start signal.
Main app screen
CONNECT
Scans for a compatible BagNode Bluetooth sensor and connects the app to live punch data. Use DISCONNECT before switching sensors.
START and STOP
START begins the selected round or quest. STOP ends the active session and saves the result when session data is available.
TARE
Zeroes the BagNode sensor before training. Use it while the bag is still, before the first punch.
RESET
Clears the current live counters on the app screen so you can begin fresh.
Reading the numbers
Live power
The current impact value from the bag. Use it to compare punch intensity during the round.
Max hit
The strongest registered hit in the current session.
Hits
The number of valid hits detected by BagNode during the round.
Heart rate
If enabled and connected, this shows pulse data for training feedback. FightNode is not a medical device.
Training modes
Knockout mode
Uses 8-count and knockout style rules. This is useful when you want fight-style pressure and clear round results.
Fitness mode
Tracks training without knockout counts. Use this for general bag work, conditioning, and repeated rounds.
Camera mode
Arms video recording and adds a FightNode overlay with round time, hits, max hit, total work, and heart rate when available.
Quest length
Choose sessions such as 10s, 30s, 1 min, 2 min, 3 min, 5 min, 3x2 min, 5x3 min, 12x3 min, and 3x5 min.
Camera and video
Open Camera Setup
Use CAMERA SETUP to position the phone before recording. A tripod or wall mount gives the best result.
Choose quest and mode
Select the round length and training mode, then start recording. The app gives a countdown and records the session.
Save mode
Use SAVE MODE if you want camera recording to stay enabled for future sessions.
Share video
After recording, use SHARE VIDEO or the share button in history to send the saved FightNode session video.
Heart rate monitor
Connect monitor
Tap CONNECT HEART RATE MONITOR and select a supported Bluetooth heart rate device.
Live pulse
When connected, the app shows heart rate during the round and can save start, average, max, and end heart rate.
History graph
Saved sessions can include a heart rate graph so you can compare cardio response across training sessions.
Medical note
Heart rate is for training feedback only. FightNode is not a medical device.
History and rankings
History
HISTORY shows saved sessions, total hits, total kilograms, best hit, calories, impact graphs, and heart rate graphs when available.
Details
Open session details to inspect the impact graph and session stats. You can delete a single session or clear history.
Ranking
RANKING compares results by max hit or total kilograms. You can filter by quest, age group, gender, and weight class.
Public upload
If Public ranking is enabled in Settings, saved sessions can upload to the online ranking. Turn it off to keep results local only.
Profile and account
Login or guest
You can create an account, log in, or use guest mode. An account keeps ranking identity clearer across sessions.
Profile
PROFILE stores username, age, weight, height, gender, country, and gym. These values help history, calories, and ranking filters.
Account status
The ACCOUNT OK or GUEST MODE button shows whether you are using a logged-in account or a guest account.
Logout
Use LOGOUT when changing user or ending a shared device session.
Settings and extra buttons
Settings
SETTINGS lets you choose Knockout, Fitness, or Camera mode, enable camera recording, and turn Public ranking on or off.

Troubleshooting
BagNode does not appear
Check that Bluetooth is on, restart the sensor, keep the phone nearby, and scan again from the app.
No hits are counted
Make sure the sensor is firmly mounted, the round has started, and the bag is not moving before setup.
Numbers look wrong
Stop the round, let the bag settle, reconnect BagNode, and start a new session.
App loses connection
Move closer to the sensor, reduce Bluetooth interference, and reconnect before continuing the session.
Safety
Warm up thoroughly before training. We recommend using hand wraps and proper boxing gloves when hitting the bag. Keep the bag area clear, train with control, and stop immediately if you feel pain, dizziness, or unusual discomfort. FightNode is for training feedback only and does not replace a coach, doctor, or medical device.
