Date Calculator
Read full descriptionHide full description
How many days between two dates? Get the exact answer in one tap ā no counting squares on a calendar, no math in your head. Pick a start date and an end date, and DateDiff breaks the gap down into every unit at once: years, months, weeks, and days, plus total days, total weeks, total months, and total hours. It works the other way too ā add or subtract days, weeks, months, or years from any date to land on the exact day you need. Every result is calculated on-device and stays accurate across leap years and century rules. WHAT YOU GET - The precise span between any two dates in years, months, weeks, and days, all shown together - Add or subtract time to find a future or past date instantly - Business-day counting that skips weekends and imported holidays - Country holiday packs plus your own custom days off, so workday counts match your calendar - Saved date pairs with upcoming milestones and live countdowns to the days that matter - A plain-text export of your saved calculations to share or keep PERFECT FOR - Planners counting down to a trip, wedding, or big event - Anyone working out an exact age from a birth date - Project managers tracking deadlines in real working days - Curious minds settling "how long ago" and "how far away" questions WHY NOT JUST COUNT ON A CALENDAR Flipping through months and tallying days is slow and easy to get wrong ā one skipped weekend or forgotten leap day throws the whole number off. DateDiff does the counting for you and stays exact every time, including the weekend and holiday skips that hand-counting always misses. PRIVACY Everything stays on your device. No account, no ads, no tracking ā the app works fully offline. FULL ACCESS DateDiff Pro unlocks workday and business-day counting, country and custom holiday packs, saved date pairs, upcoming milestones, and export. It is available as a weekly or yearly subscription, or a one-time lifetime purchase. The date difference and add/subtract calculators are free to use. Stop counting on your fingers ā get the exact answer in one tap.

Moonflower gives every website a beautiful dark mode in Safari ā designed to feel like it was always meant to be there. Create your own themes with exactly the colors you want, and fine-tune every website individually: its own theme, its own on/off rule, its own exceptions. Most sites still don't offer a dark theme. Moonflower fixes that: its engine reads each page's actual colors and generates a tailor-made dark theme on the fly, so text stays crisp, images stay natural, and nothing looks washed out or inverted. DARK MODE, DONE PROPERLY ⢠Works on every website, automatically ⢠Dynamic colors: a custom dark theme generated per site ā not a crude filter ⢠Respects sites that already have a dark mode (or override them if you prefer) ⢠Smart image handling: photos stay untouched, bright diagrams and logos are gently adapted ⢠Flash-free page loads ā pages paint dark from the first moment DESIGN YOUR OWN THEMES ⢠Six hand-tuned themes to start: Black, Dark, Gray, Sepia, Paper, Focus ⢠Create unlimited custom themes ā pick your exact background and text colors ⢠Fine-tune image brightness, grayscale, and sepia per theme ⢠Edit with a live preview on a real article, so you see every change instantly FINE-TUNE EVERY WEBSITE ⢠Auto, On, or Off ā globally or per site ⢠Give each website its own theme ⢠Pause a site until tomorrow with one tap ⢠Ignore a site's built-in dark mode when yours looks better ⢠Keyboard shortcuts for toggling, cycling themes, and pausing A READER BUILT IN ⢠One tap turns any article into a clean, beautiful reading view ⢠Apple Books-style themes ā each with a light and dark variant ⢠Adjustable text size, and your custom reader themes come along EVERYWHERE YOU BROWSE ⢠iPhone, iPad, and Mac ⢠iCloud sync keeps your themes and site settings identical on all your devices PRIVATE BY DESIGN Moonflower collects no data. Which sites you visit never leaves your device ā all darkening happens locally, with no accounts, no analytics, and no tracking of any kind. FAIR PRICING Free for 3 days, full-featured.

Verdict
The clearest difference is update cadence: Moonflower at every 6 weeks against Date Calculator's every 3 months. Moonflower also leads on device support (3 vs 1). Date Calculator's advantage is iOS requirement (17.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.
