This application is designed to be used with the Mopeka TankCheck sensor. The Tank Check application can measure the LPG propane level to tell you the exact fill level and when your tank is empty. It can be used on tanks found in RVs, heaters, BBQ grills, etc. The Tank Check sensors are magnetically stuck to the bottom of your propane tank and will periodically measure and wirelessly send the fill level or percentage to the Tank Check app. Stick it on the bottom of your tank and know exactly when you are running low on propane! This technology is patent pending. More info about the TankCheck Sensor and links to purchase the sensors can be found on the Mopeka website at http://www.mopeka.com Usage: 1. To pair your Tank Check sensor to the phone, simply press the "Sync" button on the back of the sensor while the app's main screen is visible. The first time you use your Tank Check sensor you must press the "Sync" button 5 times in a row in order to wake up the sensor. 2. Place the Tank Check sensor in the center of the underside of the tank. Most tanks have a small "flat" spot on the center and this is the nominal location for the sensor. 3. Flip the tank over. Once the fluid has settled the app will display a reading. Note that the LPG fluid will be sloshing around in the tank for a few minutes and the quality of the measurements will be low until this has stabilized.

ReceptionRating · Positive reviews · Number of ratings

Renogy holds the better App Store score, 3.8 against 2.9. That said, the two scores are not equally well evidenced: Renogy has 799 ratings behind it against 58, so its average is the more settled of the two. Written reviews complicate that: 24% of Mopeka TankCheck's written reviews are positive against 11% of Renogy's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Mopeka TankCheck ships an update fortnightly, Renogy every 2 weeks. The most recent releases landed on September 14, 2026 and September 23, 2026 respectively.
