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.

Verdict
The clearest difference is price: Tracker at Free against GSafe Watch's $5.99. Tracker also leads on update cadence (every 2 days vs every 3 months). GSafe Watch's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.6). On ads and in-app purchases there is nothing between them.
