HT Tracker is used to maintain the track of humidity and temperature readings and display the fluctuation of the same in both real and historical time (days, weeks, months and years). Both readings are displayed in numbers and graphs with respective units i.e. Humidity in % and Temperature in Celsius or Fahrenheit as selected by the end user. In addition to the monitoring current environmental conditions and time series displays, the graph view gives you an instant insight what temperature and humidity levels are widespread in a location and what were the extremes for the previous hour, day, week, month and year respectively. By dragging the slider of humidity and temperature you can set the optimal range for any situation. Then when your iOS device is within that range of the sensor (150+ foot line of sight), it will be continuously monitoring conditional changes. ———— About data sends by BLE Sensor————— The BLE Sensor will continuously monitor conditions although when you are away and pushed the data seamlessly to our device so that we can see the changes and will notify if there are any problematic condition i.e. readings beyond the certain limit set by you. High and low temperature/humidity alerts are set up by the user. Alerts will be sent to the smartphone when readings are outside the ranges set by the user from settings. HT Tracker has the ability to re-calibrate humidity readings if necessary. Also, you can set the alert time for the notifications. ———— Bluetooth Background ————— It is important for the app to stay connected with Bluetooth so the BLE sensor throws the temperature and humidity changes and the user can use their phone for other tasks while the sensor is throwing data to the phone. ## Key features - Real-time and historical data tracking - Graph visualization of fluctuations - Customizable optimal ranges - High/low temperature and humidity alerts - BLE sensor data synchronization - Humidity re-calibration ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/ht-tracker/id1316520962/reviews.md ### 5/5 — Excellent humidity tracker *2025-12-08* I have been using the HT Tracker for just over 2 years. I had to reinstall / resync one time. Otherwise it’s been extremely reliable and accurate. It doesn’t look like it is available anymore. Too bad. I was hoping for an Android version. ### 2/5 — Seems abandoned *2024-11-14* The app has not appeared to be updated in 5 years. I purchased the BT device last year and it has already failed. The temperature in my guitar case is reading 140 degrees. Would like to see an ipad version or at least the ability to zoom in on the data since the print is so small. Also a percentage of battery level would be nice. ### 4/5 — Ok, could be better *2023-11-29* It actually works pretty well and I get alerts when the humidity drops too low. The app could definitely use some bug fixes. One particularly is it won’t let you rename your tracker. It freezes and never completes. ## Frequently asked questions about HT Tracker ### What is HT Tracker used for? HT Tracker is used to monitor and track humidity and temperature readings.
