Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Any.do

  • Bare-bones free plan: lacks recurring tasks and third-party integrations available only in paid plans
  • Short planning window: only allows planning up to seven days ahead, limiting long-term project planning
  • Limited desktop performance: web and desktop versions struggle with functionality and responsiveness
  • Slow customer support: email support takes approximately 48 hours to respond
  • Missing drag-and-drop: inability to drag tasks between lists creates workflow friction

Cassandra

  • No support for joins across tables
  • No ACID transactions across multiple rows
  • Data model must be designed around query patterns upfront, making schema evolution difficult
  • Partition key misconfigurations can cause uneven data distribution and hotspots that degrade performance
