Funf
Read full descriptionHide full description
Funf is a to-do app for people who don't like lists or guilt. Do what actually matters. Nothing else is important. I have tried every to-do app there is. None of them survived real life. They either drowned me in features, or turned into a place where I collected guilt. I needed something that forces me to choose. Something that makes me do the important things, not just whatever lands in my lap. And a place to empty my head before bed, so I sleep better. So I built Funf. Every day has five slots. That is not a setting, it is the whole point. โโโ Here's how it works: tasks live in a small window around today, five days back and five ahead. If a day is full, something has to give. That little bit of friction is the trick: you quickly find out what actually matters. The best part is the calendar. Your five sync straight into the calendar you already use โ Apple, Google or Outlook โ as all-day blocks above your meetings, not below. Meetings fill your hours; your five set the direction. What you decided matters is the first thing you see when the day starts. On iPhone, Funf lives on your Home Screen with a widget you can check off without opening the app. Inside, eleven days are one calm scroll, with a day index along the edge: tap to jump, drag to scrub. Hold a task to lift it, and drop it on another day. Native all the way! On Mac, Funf lives in the menu bar, and the mark up there is the counter: one stroke per completed task, and the slash only at five out of five. โโฅN catches a thought from any app โ type, press Enter, done. The whole keyboard works, and you can drag tasks between days. A proper native Mac app! History is the year in green: twelve months as grids, greener the more you got done. No streaks, no points, no run to break. Just a year you can look back on. And be proud of. Didn't finish something? At midnight it slips quietly out of sight. If it still matters, write it in again tomorrow. Finished? No confetti. Just a quiet nod โ and a history that remembers everything you actually got done. No projects, no tags, no priorities. No ads, no tracking. Just five things. Done and dusted. One download covers both iPhone and Mac. Free. Five is focus. A good handful. All good things come in โฆ funf.

Prubi โ the AI notes app that gets prettier as you write. One line becomes a plan, and Prubi reminds you before you forget. A line a day, in Korean โ write one line about your day and see it as natural Korean phrases: the sentence, how it sounds, and what each part means. Listen, read along, then hide it and write it in Korean yourself. WHY YOU'LL WANT TO OPEN IT โข Share as one card, no link โ today's line turns into a picture card. Anyone can read it, even without the app. โข 16 pixel friends โ as your writing days add up, a new friend drops by and walks along the bottom of the screen. Can you collect them all? โข A desk that grows with you โ 28 papers, tapes, props and friends to decorate every day, nothing to buy. โข One line is enough โ no long entries, and skipping a day is fine. Start light with 7 Days of Gratitude. EVERYDAY PROBLEMS, MADE EASY โข Jot it before it slips away โ write straight from Home. No folder to pick first. โข Notes become plans โ write one line, tap "Let Prubi sort this", and the date and time land on your calendar. โข Check it, color it, remind me โ checklists, 6 colors and reminders. โข Your week at a glance โ weekly planner, a 24-hour day view and D-day. โข "Where did I write that?" โ ask, and the AI finds it in your own notes and shows exactly which notes it read. BUILT TO TRUST, BUILT TO LAST โข A vault only you can open โ passwords, account numbers and ID photos are encrypted on your device before upload; the server keeps only ciphertext. โข Write on your phone, continue on PC โ same account, same notes on phone, PC and tablet. โข 16 languages ยท no ads ยท no data selling ยท your notes are not used to train AI models. โข Export notes to Word, PDF or Excel, and delete your account any time. START WITH ONE LINE TODAY Create your free account now โ every line you write is saved to it, so nothing is lost even if you change phones. Free to start. When you want to go deeper, continue with an annual or lifetime plan inside the app. On a computer, pick up right where you left off at prubi.online with the same account. Made by Gonggansai

Verdict
The clearest difference is in-app purchases: Funf at none against Prubi's 3. Prubi's advantage is update cadence (every 4 days vs monthly) and iOS requirement (16.4 vs 26.0). On price, ads and device support there is nothing between them.
