What's the best Android app for selling unwanted household items quickly with minimal hassle?

Mercari is particularly well-suited for users looking to quickly convert household clutter into cash without extensive back-and-forth negotiations. The platform's automated seller rating system, which posts favorable feedback after three days if buyers don't respond, streamlines the selling experience significantly. This feature proves especially useful for casual sellers who want to avoid the constant monitoring required by some competing platforms. The app regularly offers site-wide holiday sales and category-specific discounts that help move inventory faster. However, some interface quirks occasionally surface—reviews indicate the messaging system can be problematic, with text boxes sometimes obscured by keyboards during typing. The mandatory 'Buyer Protection' fee (which some users argue functions more as a general service fee) provides transaction security but adds to overall costs. Despite these minor issues, Mercari's balance of seller-friendly policies and broad buyer base makes it a practical choice for decluttering efforts.
