A new App has been released that can help parents automate child support payments, track child-related costs, upload receipts, and send medical expense invoices. The maximum functionality would require both parents to download and use the application, but it can also be useful if only one parent uses it for tracking purposes.
The free version stores six months of information, the premium version ($120/year) allows long-term storage of documents, and a “legal” version ($156/year) allows parents to make the records available to their attorneys.
