You can preset intervals of 30 minutes, 60 minutes, 90 minutes, 2 hours, and 3 hours. The watch has an inbuilt proximity sensor and only sounds alerts when it is worn so no need to turn it off at night. How smart is that?
Promising review: “Obsessed!! My 4-year-old has been potty-trained for well over a year. Around the time the pandemic started, she started having accidents. It got to the point of needing new underwear two to four times almost every day. Since getting this watch almost a week ago, the accidents have completely stopped! She’s worried we’ll return it if it doesn’t work so she both goes when the timer goes off (every two hours for us) as well as when she feels the urge. We keep it on vibrate so there’s no issue in school. And we purposely set it for a time frame that it never goes off during circle time or story time so she never has a reason to ignore it. Best $20 I’ve ever spent. Worth every penny! Hope the results last.” —NJ Mom
Promising review: “We were having the HARDEST time with potty training. After this purchase my L.O. loves when the music goes off and asks ‘Mom, what time is it?’ Every time it goes off. Wish we would have purchased sooner!” — Womanonamission
