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. ## Key features - Measures exact LPG propane fill level - Displays tank empty status - Works with RVs, heaters, and grills - Wireless sensor data transmission - Magnetic sensor attachment ## Recent user reviews (10 of 112) All indexed reviews: https://appshunter.io/ios/app/mopeka-tankcheck/id981959807/reviews.md ### 1/5 — Out of date!! App needs revamp and update *2026-06-10, version 2.5.71* I’ve purchased 4 of these because of either failure or the battery is dead. The technology needs to match the expensive price. ### 1/5 — Mopeka *2026-05-03, version 2.5.71* N’a jamais bien fonctionné ### 2/5 — Funktioniert *2026-04-02, version 2.5.71* Funktioniert soweit gut, aber ich verstehe nicht essen man da keine Statistik einbaut? Einfach ein Diagramm mit den Zeiten der Messungen und wann es alle ist. Total easy Riesen Mehrwert. Oder zusätzlich noch eine Berechnung der Restlaufzeit aus dem Verbrauch der letzten 2/24/48 Stunden. Ich kann nicht programmieren, aber dafür bräuchte ich nicht mal nen paar Stunden … Gerät gut, App absoluter ….. ihr wisst schon ### 1/5 — No 15lb tank option *2026-02-18, version 2.5.71* This doesn’t make any sense. Most folks have 15lb tanks and the smallest selection on the app is 20lbs. They have an arbitrary option to input the height of your tank in to circumvent that issue, however, IT DOESN’T WORK. When I put in my Blue Rihno 28” tank that was just filled, it showed it at 57% full no matter how many times I reservoir zero’d it. Then when I selected back to 20lbs it showed 100% capacity. So what’s accurate? This is terribly advertised and horribly implemented for something that cost this much money. ### 1/5 — Junk *2026-01-23, version 2.5.71* Tank sensor What a piece of junk! Replace battery and they won’t since back up! The app will keep running! App will drain your battery! ### 3/5 — Ist zu verbessern *2026-01-16, version 2.5.71* Grundsätzlich funktioniert alles. Leider ist die App nicht auf Deutsch umstellbar. Ist aber zu verschmerzen. Leider keine Auswahl von 5 kg Flaschen. Eine Anzeige des Füllstandes in Kg wäre durch einfache Umrechnung der Prozentualen Füllung auch möglich. Eine Statistische Auswertung ist auch eine schöne Sache „ Bei derzeitigen Gasverbrauch hält die Flasche noch X Stunden“. ### 2/5 — Meh *2026-01-13, version 2.5.71* They work great, when they work. I don’t know why I keep buying them but I do. I’m on my 4th one and this one barely made it a month before it stopped working. You’d think for what they charge for them they would be better quality but sadly they’re not. Trying to contact them is another nightmare so this will be the last one I will buy, they’re $70 worth of junk. ### 1/5 — Kills phone battery *2025-11-24, version 2.5.71* Please enable a way to conserve battery life and increase tank level check time to 1 time per day. A maximum length of 30 second intervals is ridiculous, too short of an interval, and a waste of resources. In the last 10 days, your app has consumed 9% battery usage. That’s a complete waste. ### 3/5 — Nur Englisch *2025-11-13, version 2.5.71* Leider kann die App nicht auf deutsche Sprache umgestellt werden ### 1/5 — Braucht kein Mensch , weil es nicht funktioniert *2025-11-10, version 2.5.71* Viel zu teuer für diese Ungenauigkeit. Er macht leider nicht was er soll und nervt mit seinen Alarm , die Flasche wäre leer, dabei ist sie voll . ## Frequently asked questions about Mopeka TankCheck ### What does the Mopeka TankCheck app do?

To pair the sensor, press the 'Sync' button on the back while the app's main screen is visible. For the first use, you need to press the 'Sync' button five times in a row to wake up the sensor. Then, place the sensor on the center underside of your propane tank. ### Is the Mopeka TankCheck app free to use? Yes, the application itself is free to download and use.

This app is designed for use with tanks containing LPG propane. It is suitable for tanks found in RVs, heaters, and BBQ grills, among other common propane-powered appliances. ### How accurate are the readings?
