Most impulse buys regret themselves — if you just wait. ColdWallet puts a 48-hour lock between you and your next impulse purchase. The moment you want to buy something, add it. The clock starts. 48 hours later, most urges are gone. The ones that survive? You probably actually needed them. What you get: - 48-hour impulse lock — every want sits in a cooldown queue before you can act on it - Color-coded daily budget — green, yellow, or red at a glance so you always know where you stand - No-spend streak — tracks consecutive days without unplanned spending; planned expenses don't break it - Money-saved total — every resisted impulse adds up; watch your savings grow - Weekly summary with chart — see your spending patterns at a glance - Local notifications — daily check-in reminder and an alert when your 48-hour wait is up - 100% on-device — all data lives on your device; no account, no sync, no cloud - No third-party SDKs — zero trackers, zero analytics, zero ads ColdWallet is not a budgeting spreadsheet. It's a friction device. It slows you down just enough that your future self gets a vote.
