Note: I am a dinosaur that deliberately has no browser on smartphone.
Landing page is giant photo of person using computer in uncomfortable and dangerous position, and no clear info how this actually works ( https://taskratchet.com/ )
https://app.taskratchet.com/ has massive amount of unused space and still no clear explanation
“24 hours after that, the charge will be captured.” is completely unclear technical term - is it about reversibility of charge and how refund is done on a technical side? (from https://docs.taskratchet.com/faq.html )
https://docs.taskratchet.com/faq.html is not answering how TaskRatchet “knows” about whatever goal is completed. Is it just manual data entry? If yes, then it is basically interface to quickly create oneshot Beeminder goals (it may be still useful for people! Interface may be a difference between DOS and Windows 3.1).
BTW, your ToS forbids opening more than one tab with TaskRatchet or entering any data on the site, even registering is violation of ToS as it not only viewing page (“Permission is granted to temporarily download one copy of the materials (information or software) on TaskRatchet’s website for personal, non-commercial transitory viewing only.”).
" Can I try TaskRatchet out without adding my payment details?
Currently you can" - it seems to not be possible
