Today, there is an app, website, or software platform for just about anything (including finding someone to walk your dog).
But when it comes to trying to remembering everything there is 1 app I can't live without:
Twos https://www.twosapp.com/ and here's why:
I can keep a running record of everything that comes across my mind during the day on the today page. Whether that is a task, thought, idea, recommendation, links, photos, events it can capture everything.
Unfinished tasks will automatically roll over to the next day. I’ve lost count of how many tasks I have missed because I haven’t been able to do them on the day I had planned and they disappear into eternity.
I have my calendar integrated so I can see within the app if a task I am going to set a reminder for will clash with another event.
You can nest lists and make sub lists within those lists. If you are a GTD or PARA aficionado you can easily keep everything nice and tidy.
The “ Your Week” list is particularly helpful when I do my weekly review. I can look back and see anything I have missed, need to make a note for, want to do something with.
If you want to never forget anything, have a single app to use as an inbox and stop panicking that you’ve lost that important thing, I can't recommend using this app enough.
