## Abstract (arXiv)

Reliable mobile GUI agents must retain and reuse information across actions, applications, and repeated interactions. However, current benchmarks systematically underrepresent these memory demands: only 5.2-11.8 percent of their tasks are memory-related, and none evaluates cross-session learning. We introduce MemGUI-Bench, a comprehensive memory-centric benchmark that assesses both short-term information retention and long-term experience accumulation through pass@k protocols and staged LLM-as-judge evaluation. Our contributions include: (1) a systematic taxonomy of short- and long-term memory based on 11 agents across 5 architectures; (2) a snapshot-based suite of 128 tasks across 26 applications, organized into 64 mirror pairs, where 89.8 percent require cross-temporal and cross-spatial retention; (3) MemGUI-Eval, an automated 3-stage Progressive Scrutiny pipeline with 7 hierarchical metrics spanning memory fidelity, learning effectiveness, and execution efficiency; and (4) an assessment of 11 state-of-the-art agents guided by 6 research questions. Our experiments reveal substantial memory deficits across all evaluated systems, including 4-10x capability gaps on memory-intensive tasks. They further show that short-term memory is indispensable, while explicit long-term memory improves cross-session learning by 21.9 percentage points, with cross-application transfer and computational cost remaining major bottlenecks. We additionally identify 5 distinct failure modes and synthesize 5 actionable design implications for future memory-enhanced agents. All resources, including code, benchmark, and evaluation results, will be fully open-sourced and continuously maintained at https://memgui-bench.github.io/.
