Daa! turns the messages you already get — school notes, class payments, birthday parties, subscription renewals — into gentle reminders you'll actually see. And it quietly keeps track of what the family spends, and what you save when you cancel something. Built for busy parents. No account. No cloud. Nothing leaves your phone. CAPTURE IN ONE TAP Share a message from any app straight to Daa!, or paste it into Quick add. Daa! reads the date, the amount and what it's about, then shows you a card to check. One tap and it's saved. Typing it in yourself is always there as a fallback. TODAY, AT A GLANCE Today shows what's happening now, what's due soon, and what's coming up. Tap Daa! on a card once it's handled. Nothing scheduled? Quiet days count as wins too — Daa! will never make you feel behind. MONEY, WITHOUT LINKING A BANK Payments and subscriptions land in Money as you confirm them: spent this month, broken down by category and by family member, plus what you've saved this year by cancelling things no one uses any more. Both numbers come from your own taps — nothing reads your bank. GENTLE REMINDERS, NOT ALARMS A short morning digest of the day ahead, and an evening look at tomorrow. Optional nudges for the small things you keep meaning to do. Warm, quiet, never nagging. EVERYTHING STAYS ON YOUR DEVICE No account to create. No sign-in. No analytics, no tracking, no servers. Your family's reminders and amounts live on your phone and nowhere else — which is also why Daa! works with no connection at all. Export a backup whenever you like. ENGLISH AND RUSSIAN The whole app in both languages, switchable any time. Don't forget what matters.

Verdict
The clearest difference is in-app purchases: Daa! at none against PDF Book Reader's 2. Daa! also leads on ads (none vs shown). PDF Book Reader's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price and update cadence there is nothing between them.
