I actually do get some of my questions sent to me by text When you sign up and subscribe, you can choose to receive your questions by either email or text.
For graphs, I actually don't personally use them much as most of my manual questions are for text replies - I've found the accountability of answering the questions every day helps keep me on track every day. For the two questions I mentioned, it's really helpful for me to periodically review my answers every few weeks and see how far i've come on various projects. It's easy for me to get stuck in the weeds, and being able to quickly review weeks or months of progress is really valuable for me.
One graph that I do like is the line graph for my "how was the day (1-10)" question. It's encouraging to me to look back at the troughs, remember the struggle, and see how I overcame it days later. With more complicated or objective data, i might graph more, but for the subjective stuff I measure a simple line graph over time is plenty for me.
