Not an answer to your software question, but you will very likely struggle with overheating since your phone will almost necessarily be in direct sunlight for hours at a time. If you really need to do this, avoid mounting your phone with a case and try to use a mount that does not cover too much of your phone's rear surface- cases and mounts can make it harder for your phone to dissipate heat.

I have two bikes that I ride frequently- commuting or otherwise. I have a saddle bag with a quick release latch that makes it easy to switch between bikes depending on which one I'm going to be riding. I keep two tubes (I run 28mm tires so the tubes aren't huge), a small pump, tire levers, a multi tool, a small tubeless plug kit, and a little shop rag.
My nicer bike is set up tubeless so I don't need to deal with flats often, but I have needed to stop and put in some extra air after a persistent leak before. My other bike runs tubes and I do get flats sometimes despite running Continental GP 4 Seasons tires.
The worst part is the pump. It takes forever and it's physically awkward. Electric pumps are getting smaller and cheaper, but I worry I'll forget to keep it charged.
I had about 110 when I first best the main story. Since then I've been picking it back up in bits to unlock the rest of the depths map and explore islands I've missed. Guessing I'm around 130 or so at this point.
There are still a ton of shrines and side quests I haven't done, but I doubt I'll ever 100 percent it.
