What's the best iOS app for splitting rent payments to avoid late fees?

Flex is a specialized payment app designed for tenants who need flexibility with rent payments. The app allows users to split their monthly rent into multiple installments throughout the month, aligning payment dates with personal cash flow. Users can schedule payments according to their pay cycle, reducing the financial strain of a single large payment. The system automatically processes payments and sends reminders, helping ensure timely submissions to landlords. Reviews indicate this feature has helped many users avoid late payment penalties and maintain better budgeting control. Customer service receives consistent praise for resolving payment issues promptly. However, the service requires landlord participation in the Flex network, which may limit availability in some rental situations. Some users note the interface, while functional, could benefit from more visual payment tracking features. For renters living paycheck-to-paycheck or those with irregular income, the app provides a practical solution for maintaining consistent rent payments without incurring late fees.
