I previously wrote a review where I was unable to connect to sensor via iPhone appI tried it again in the summer of 2022 and it actually worked.Over the winter of 2022-2023, I removed the batteries from both sensors to prevent batteries draining.Reconnected tpms sensors in spring 2023Once again, they connected and appear to be working correctly.I insert the battery after I press the app button to pair sensor and quickly screw sensor onto the valve stem.

Bought this at Daytona bike week because whenever I check tire pressure I have to lay down on the ground and I have to have someone help me line up the valves so I can get to them. Always a pain. So I saw this for $80 and said “wow, I could just go to garage with my cell before a ride, open the app and read the tire pressure.” If only it actually worked. Three weeks is all I have had this for and the app worked maybe 50 percent of the time. Very frustrated with the purchase. very unreliable product. I am asking for my money back. At least when I lay down on the floor with the tire gauge I get a reading

When this app starts up it shows previous readings. It takes awhile to update. There id no indication of previous or current. It would be better if it started up blank, or, if if left running, it blanked when connection to the tpm devices was lost.
