That vape habit is quietly costing you hundreds — maybe thousands — a year. Vapend does the math you've been avoiding, then turns every skipped puff into real money back in your pocket. No lectures. No "quit today or else." Vapend meets you where you are and helps you move at your own pace. SEE WHAT IT REALLY COSTS Log what you spend and Vapend shows the shocking yearly total — in money you get, like "13 pairs of headphones" or "521 tacos." Once you see the number, it's hard to unsee. QUIT WHEN YOU'RE READY Most apps demand you stop on day one. Vapend doesn't. A gentle 14-day program builds insight and motivation first, so quitting feels like your decision — not a punishment. MARK YOUR LAST PUFF When you're ready, a simple last-puff ritual turns the moment into something you'll remember. It's the line between "before" and "after." WATCH YOUR SAVINGS GROW Quit Mode counts every vape-free day and every dollar you keep. A breathe button for the hard moments, health milestones to look forward to, and a number that only goes up. WHAT YOU GET ◆ Real-cost dashboard - your habit translated into things you actually want ◆ 14-day insight program - one small, motivating step a day ◆ Last-puff ritual - a meaningful way to draw the line ◆ Quit Mode counter - vape-free days + money saved, growing daily ◆ Health milestones - see what your body reclaims over time ◆ Shareable savings card - show friends what you've kept YOUR DATA STAYS YOURS Vapend works fully offline. Your purchases, prices, and progress live only on your device — never uploaded, never sold. No account, no sign-up, no tracking across apps.

Verdict

The call

The clearest difference is in-app purchases: Vapend at none against Sleep Calculator App's 1. Vapend also leads on ads (none vs shown) and update cadence (every 5 days vs every 8 months). Sleep Calculator App's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 18.0). On price there is nothing between them.
