I was thinking a lot about this problem. And finally, I got a solution. I have developed a free application 'Zihi checklists' to solve such problems. It is available at App Store:
Google Play: https://play.google.com/store/apps/details?id=pro.zihi.zihichecklist
And at the website: https://zihichecklists.com/
What is it? The service allows you to create a check-list (or save a good public check-list from another person) and use it!
Here is a checklist from Galina Vinogradova for international sprint races:
Just save it and use it before the race! Mark point as "done" and you will be sure that everything is under control!
If you want to create a checklist only for yourself - just keep it "Private".
There is an opportunity to create check-lists for 280 sports and activities (such as Travel, Learning, Pets, Health&Wellbeing, Reading, and so on).
Also, you can put a link to other resources (e.g., websites of your sponsors or some information sources) into each check-point!
Pass on your Experience - this is the motto of this project!
Please, download the app and start using it! This is totally free, and I've made it for you, my friends.
