Blocksi on my PC's and Xblock on my iPad. Both support password protection against any changes, so I am using that. But I would refer you to this thread. There are many, with more functions than the ones I am using. I am fine with those two I mentioned so not in a need of more functions.
Well I fucked up. Day 0 again. Focusing on not counting days this time. Just knowing the date of the relapse. Will update if I achieve some major breakthrough this way ✌
