GSafe for Watch allows you to track your GHB/GBL doses directly from your wrist, from your Apple Watch, without your phone. It records the history of your doses and displays a big timer since your last dose, limiting the risks of mistakes and reducing harm. A complication also allows you to see in a glimpse the time elapsed since your last dose, without having to open the app. It avoids that you take G too early by mistake. Note that this app is currently not synchronised with the GSafe app on your phone. If you don't see the app on your watch after buying it, search it from the App Store app directly from your Apple Watch to download and install it on the watch.
