This is the comparison most families actually face, because it starts from the teen’s request rather than the parent’s research. Both apps are free and both admit 13-year-olds — but the public records behind them tell very different stories, and this page walks through the three that matter: the insurance path, the complaint file, and what each product builds for the teen by 18.
Cash App vs Step: the app they want vs the account they need
Most teens arrive at this choice from opposite directions: they ask for Cash App because their friends use it, and parents discover Step while researching. Both are $0. The records separate them fast.
Step is built as a teen account: purpose-built oversight, and the secured Step Visa Card that builds credit history before 18 — a structural head start no peer-payment app offers. Cash App’s teen mode is an access layer on an adult product: a sponsor can view activity and pause the account, but there are no category controls, no chores, no credit building.
The two lines parents should read twice
First, insurance: Step routes deposits through Evolve Bank & Trust (FDIC certificate 1299, active per BankFind). Cash App’s FDIC coverage is conditional — it applies in specific configurations, per the terms of its active CFPB prepaid agreement — which is a meaningful difference for money that sits in the app rather than passing through it.
Second, the complaint file: our latest pull of the CFPB Consumer Complaint Database shows 67,086 complaints against Block, Inc. and zero under Step Mobile, Inc. Block’s scale explains part of that number; it does not explain it away.
The pragmatic setup many families land on
Step as the primary account (balance, savings, credit building), Cash App as a sponsored secondary for peer payments — with the balance kept near zero. That uses each product for what its record supports, and both fiches on this site track the fee schedules and FDIC status so the setup can be re-checked yearly.
What each builds by age 18
The forward-looking difference: a teen who runs Step from 14 to 18 exits with up to four years of credit history from the secured Step Visa Card — an on-ramp to adult credit that most banks cannot offer minors at all. A teen who runs Cash App over the same years exits with a payment habit and no record. Neither app charges for those years, so the cost of choosing is invisible until it isn’t. Our teen ranking weighs this build-something dimension across all seven programs we track, and each fiche’s evidence trail — CFPB agreement, FDIC certificate, complaint breakdown — stays current as the products change.
