Acorns

Acorns automates investing for retirees through round-up savings, where everyday purchases round up to the nearest dollar and the difference flows into a diversified portfolio. The app offers retirement-specific accounts (IRAs) with automatic deposits and employer match where applicable, plus goal-based investing tied to specific milestones. A financial advisor algorithm manages your portfolio based on your age and risk tolerance.

This works well for seniors new to investing or those who prefer hands-off management. Acorns removes the friction of actively buying and selling; instead, your savings accumulate gradually in low-cost, diversified investments suited for long-term growth in retirement.
