Most apps do one of these. Acornlog connects them, so the time you log also keeps your habits and streaks going.
Start a live timer when you begin, or log activities afterwards. Tag them, see daily totals and find out where your hours really go. A running timer syncs across your phone and computer.
Daily, weekly or monthly habits with a target, one-tap check-offs and undo. Link a habit to a tag and logged activities count automatically.
Star the tags you care about and follow them on your dashboard as a year-long heatmap with your current streak and total hours.
Write the questions you want to answer every day, week, month, quarter or year, like “What am I grateful for?”, and let a pool of rotating questions keep it fresh.
Finally finished the chapter I was stuck on, and the evening walk by the river was beautiful.
Group tags like Running and Swimming under Exercise, and archive the ones you no longer use.
Add it to your home screen and log an activity in seconds, wherever you are.
Follows your system setting, or pick the look you like.
Tell Acornlog what you did in your own words, typed or dictated. It turns your story into activities with start times, durations and tags. Check them, tweak anything, and save.
Try itI worked on the app from 9 to half past 11, then had lunch with Anna until 1. In the afternoon I went to the gym for an hour.
Say what you learned today, whether it's a fact, a word or an idea from a book. Acornlog writes it up as a note, files it under a topic and makes flashcards for it.
Today I learned that in Postgres you can put a WHERE clause on an index, so only the rows you actually query get indexed.
An index with a WHERE clause only covers the matching rows, so it stays small and fast.
In Postgres, what is a partial index?
An index with a WHERE clause, so it only covers the rows you query.
No forms, no passwords. Your journal is ready right away.
Start a timer, describe your day, or say what you learned.
Streaks, heatmaps and totals show how you're really spending your time, and reviews keep what you learned.
Yes. Sign in with your Google account and you can use every feature without paying.
No. Acornlog runs in your browser on your phone, tablet and computer. On your phone you can add it to your home screen and it opens like a regular app.
Yes. Start a timer on your laptop and you'll see it ticking on your phone, so you can stop it from wherever you are.
Link a habit to a tag or a group of tags, for example Exercise. Every day you log a matching activity, like a run or a swim, counts toward the habit automatically.
You write or dictate what you did in your own words. Acornlog uses AI to turn it into activities with times and tags, and you check and edit everything before it's saved.
Say or write what you learned, and Acornlog turns it into a note filed under a topic, with flashcards to go with it. You can also write notes yourself and only let AI suggest the flashcards. When you review, you rate how well you knew each card, and cards you know well come back less and less often, right before you'd forget them.
Only you. Your activities, habits, diary entries and notes are tied to your account and aren't shared with anyone. When you use an AI feature, like describing your day, the text you enter is sent to OpenAI to process it and isn't stored there.
It takes a minute to set up, and a few seconds a day to keep going.
