Dots Tracker 4+

This is exactly (almost) what I was looking for. A simple interface that isn’t cluttered with extra fluff. Thank you for NOT requiring registration and trial periods!! I usually delete the apps that do. I would have rated this 5 stars if it had the following features: 1. Let me go back in time to add data before “todays date”. 2. Show me a column of dots or symbols (below) in one sheet so I can see multiple trackers at once. 3. Use multiple symbols like dots, squares, triangles, emojis so that I can easily distinguish between multiple tracker on that one sheet. I would gladly pay for these updates. Would you consider adding them? Thank you again for creating such a clean and usable interface.

I am experiencing the app force closing on its own, and when it reopens, the trackers I create are gone. If I make a tracker and close the app myself, when I reopen they are gone. I want this to work because I love the idea. I tried going through the app support link before writing a review, but the page that links to gives a 404 error. I wonder if the developer no longer supports the app 🙁
