Discount Calculator Sale Price

Read full description

The tag says 40% off. What actually comes out of your pocket at the register — and how much stays in it? PercentOff answers before the queue moves: type the price, slide to the discount, and the final price is just there, with sales tax on top if you want it. No signal needed — it works entirely offline, in the middle of any store. PercentOff also knows the maths shops hope you'll get wrong. Stacked coupons multiply, they don't add: 30% off then an extra 20% off is 44% off, not 50%. When a stack mixes percentage coupons with money-off vouchers, the order changes the total — and PercentOff spots when a cheaper order exists and reorders the stack for you. Deal comparisons are judged on real, rounded prices, with an honest tie when both come to the same amount. WHAT YOU GET • Type 59.99, slide to 40% — see 35.99 and exactly what you saved, before you reach the register • Sales tax charged on the discounted price, so the number on screen matches the receipt • "Extra 20% off clearance" decoded: the price after every step of the stack, and the true effective discount • Mixing a % coupon with a money-off voucher? A banner warns when a cheaper order exists and applies it in one tap • Two racks, two offers — 80 at 30% off vs 100 at 50% off — one straight verdict on which costs less • Paid 42 on sale and curious what it started at? Reverse mode works the original sticker price backwards PERFECT FOR • Clearance and rack shoppers who want the register price before they commit • Online checkouts where promo codes and vouchers stack in unclear ways • Resellers and thrifters checking an item's real markdown against its original price • Anyone who freezes when the sign says "extra 30% off already-reduced items" WHY NOT JUST THE PHONE CALCULATOR? It can do one percentage. But tax on the discounted price, three chained coupons in the right order, and a fair verdict between two deals turns into a fragile string of Ɨ0.7 Ɨ0.8 you'll mistype under pressure. PercentOff shows the working at every step, remembers what you saved, and never needs a connection. PRIVATE BY DEFAULT No account, no ads, no tracking. Every price you type and every calculation you save stays in a local database on your phone. Currency and decimal format follow your device automatically. FULL ACCESS PercentOff Pro unlocks the whole app: the discount and tax calculator, coupon stacking, side-by-side deal comparison, and saved history with notes. Choose a Weekly or Yearly auto-renewing subscription, or a one-time Lifetime purchase that never renews. Download PercentOff and know the register price while the tag is still in your hand.

About

RandomTimer

Read full description

Random Timer is a countdown timer that runs for a time you set, or picks a random length within a range you choose. You can also hide the clock so you don't know when it will end. Two modes • Basic: enter hours and minutes and count down. • Random: set a minimum and maximum, and the timer picks a length between them in whole minutes. You don't have to know what it picked until it goes off. Hide the time Turn on "Hide current time" before you start, or tap to hide and show the remaining time while it runs. When hidden, the display shows only --:--:--. When time is up If the app is open when time runs out, sound and vibration repeat until you tap Stop. If you've left the app, on iOS 26 or later a system alarm rings if you've given alarm permission; otherwise you get a single notification. Pause, resume and stop anytime. The countdown keeps running even if you close the app, and reopening it shows the time left. Your last mode, times and hide setting are remembered. Good to know • Times are set in hours and minutes (no seconds). • Available in English, Korean, Japanese, Simplified Chinese, Spanish, French, German, Portuguese, Russian and Hindi. • A banner ad shows at the bottom of the screen, and a full-screen ad appears every 10th launch. Each time your total timer use passes another 2 hours, an ad plays when you next start a timer; if you close that ad before it finishes, the timer won't start. • Tap Subscribe to start a monthly auto-renewing subscription that removes all ads. Subscription details • Subscribe (ad removal): 1-month auto-renewing subscription • Payment is charged to your Apple ID account. • It renews automatically unless you cancel at least 24 hours before the current period ends. • Manage or cancel it in Settings > Apple ID > Subscriptions. • Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ • Privacy Policy: https://timer.vnamu.com/privacy.html
