Official mail is written for the people who send it, not for the people who get it. Tadah reads a letter, bill, or notice and tells you three things: what it is, why you got it, and what to do next — in plain words, in English, Spanish, or Simplified Chinese. SCAN ANYTHING THAT ARRIVES Point your camera at a bill, a ticket, a school form, an insurance letter, a medical notice, a court or immigration document. Tadah pulls out the amount, the deadline, and the account or reference number you will actually need, and writes a short explanation of what triggered it. A CHECKLIST, NOT A WALL OF TEXT Every document becomes a short list of actions in order. Tap any step to see how and where to do it — the exact page to pay on, what to bring, and what to say on the phone. DEADLINES THAT REMIND YOU Due dates become reminders. Tadah handles the awkward cases: a deadline written as "within 90 days", a year the document never printed, an appointment in another timezone. GUIDES FOR THE THINGS NOBODY EXPLAINS Step-by-step help for moving, renting, a new job, a car, health coverage, and more — written for people navigating a system for the first time, with links to official .gov pages rather than someone's blog. FOR YOUR WHOLE HOUSEHOLD Keep a separate space for each person — a parent's medical letters, a child's school forms — and see all of it in one list, marked by who it belongs to. BUILT TO BE PRIVATE Your documents stay on your phone. When you scan, only the recognized text is sent for explanation — never the photo, and never your name or account. Usage statistics are opt-in: Tadah asks once, and sends nothing unless you say yes. TADAH PLUS An optional subscription that raises the scan and to-do limits, gives each person their own space, and keeps everything in sync across your devices. The core of Tadah is free and stays free — no account required to scan, explain, or set a reminder. Tadah organizes and explains documents. It is not legal, tax, medical, or immigration advice.

Verdict
The clearest difference is ratings volume: e at 21 against Tadah's 2. e also leads on iOS requirement (15.0 vs 17.0). On price, rating, review sentiment and update cadence there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Tadah sells 2 in-app purchases, starting at $6.99 per month and e sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Tadah against 5.0 for e. That said, the two scores are not equally well evidenced: e has 21 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 9, 2026 and October 22, 2026 respectively.
