Mail piling up? Snap it. Whatify tells you what each letter, bill or form is, whether you need to do anything, by when, and what happens if you don't. Then it reminds you until it's done. POINT, SNAP, KNOW • What it is: "Renewal notice: car insurance (Harbor Mutual)" • Do I need to act? Yes or no, with one plain sentence on why • What to do: up to three concrete steps, using only what the letter says • By when and how much, each with the exact line it came from • If you ignore it: only what the document actually says. Otherwise, "The letter doesn't say." • Keep or recycle EVERY NUMBER SHOWS WHERE IT CAME FROM Tap a due date or amount and Whatify highlights the line on your scan where it was printed. If a number can't be confirmed in the document, Whatify says so instead of guessing. CLEAR THE PILE IN MINUTES Scan a stack, one page per letter. Whatify sorts it into "needs you", "just FYI" and "safe to recycle". REMINDS YOU UNTIL IT'S DONE One tap for a reminder a few days before and the morning it's due, a gentle check the day after, and a Sunday "Your week" summary. Home and Lock Screen widgets show what's due next. Add a due date to your calendar, mark it done, or just file it. Reminders are always free for everything you've decoded. EXPLAINED IN YOUR LANGUAGE Have any US letter explained in Spanish, Chinese, Vietnamese, Tagalog, Arabic, Korean, Russian, Haitian Creole and more. ASK ABOUT IT "Can I dispute this?" "Write an email asking for a payment plan." Ask follow-up questions, and get draft replies and call scripts based on the document. PRIVATE BY DESIGN • Text is read on your iPhone. Card, account and Social Security numbers are hidden before anything is sent. • Your scans and results stay on your iPhone and in your own iCloud. We don't keep your documents on our servers. • No ads, no tracking, no account required to start. • Share a screenshot or PDF from any app straight into Whatify. Try it with the built-in sample letters, no mail needed. WHATIFY PLUS Free: 5 decodes a month and one follow-up question. Whatify Plus: up to 300 decodes a month, unlimited follow-ups and pile mode, with a 7-day free trial: $3.99/month or $29.99/year (US prices). Payment is charged to your Apple ID at confirmation or when the trial ends, and renews automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel in Settings → your name → Subscriptions. Whatify explains documents. It is not legal, tax or financial advice: always check important details against the original document. For court, IRS, collections or eviction letters it points you to free help.

You asked Claude for a workout plan. ChatGPT wrote you a 12-week study guide. Gemini drafted your meal prep. Then they vanished into chat history. Nudge is where those plans live. Paste the markdown once, tell it when and where you need it, and it finds you at the right moment — not a notification you swipe away, but the whole plan, ready to use. Monday 6am, on your way to the gym. Saturday morning at the grocery store. Friday afternoon when you connect to the office Wi-Fi. Three days without opening your study plan. Nudge notices, and brings it back. Five trigger types, stackable: - Schedule — days of week + time window - Location — geofencing with adjustable radius - One-time date — a specific day and time - Inactivity — resurface if you haven't checked in - Wi-Fi — trigger when you connect to a network Your workout plan can fire at 6am on weekdays and when you arrive at the gym. Your budget review can appear every Friday at noon and if you haven't looked at it in a week. Plans render the way the model wrote them. Full markdown — tables, headers, code blocks, blockquotes. Interactive checkboxes and inputs you can fill in as you go. A table of contents for long plans. Scroll position memory so you pick up exactly where you left off. Everything stays on your device. No account. No cloud. No tracking. Your plans — and whatever you generated them with — never leave your phone. Dark mode. Haptic feedback. Native iOS feel — large titles, peek preview, context menus. Categories with custom emojis. Archive, search, share, bulk organize. Free to start. Nudge Pro unlocks all five trigger types, location geofencing, and unlimited triggers for a single payment — no subscription, no recurring charges. Once. Forever.

Verdict

The call

The clearest difference is ads: Whatify at none against Nudge's shown. Nudge's advantage is update cadence (every 3 weeks vs every 16 months) and iOS requirement (16.4 vs 18.0). On price, in-app purchases and device support there is nothing between them.
