Why people look for something beyond Loop
Loop only runs on Android. The moment your day involves a work laptop, an iPad or an iPhone, there is no version of it to open, and the habits you tracked this morning are on a device in another room.
The second reason is that there is no account behind it. That is a genuine privacy advantage, and it is also why your data does not appear on a second device unless you export a file and move it yourself. If your phone is lost, so is the history you did not export.
The third is scope. Loop tracks habits, deliberately and well. It does not hold the weekly goals, the longer-term plans or the small daily tasks that sit around those habits.
