Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Dionz

It's designed for those who find traditional journaling difficult and prefer a more interactive, visual approach to memory keeping.

Your story becomes a tiny asteroid. You talked to Omo. Somehow, your whole day stayed with you. Omo is a scruffy little alien who crash-landed on a tiny asteroid while trying to reach Earth. All Omo has is an old radio and a chat window that stays open for your day. Tell Omo what happened today—the funny part, the comment that stayed with you, or the story that feels too small to tell anyone else. As you chat, Dionz organizes the moments from your day. Keywords from your stories become tiny asteroids. At the end of the day, they come together as a satellite, while your daily log is saved to your calendar. No blank page. No long entry. Just chat with Omo and let your day take shape. ### Features - One-on-one AI chat with Omo - Automatic daily logs based on your conversations - Keyword asteroids created from everyday stories - A daily satellite made from your collected asteroids - Review and edit automatically generated records - Revisit past days through the calendar ### Dionz is for you if you - Want to keep a diary but struggle to stay consistent - Find chatting easier than writing on a blank page - Like characters, collecting, and visual journaling - Want an easy way to remember everyday moments - Want to keep your day in pictures rather than paragraphs ### Please note - Dionz is not a therapy, counseling or diagnostic service. - Omo is a friendly character who listens without defining or diagnosing your emotions. - You can review and edit automatically generated records. - Conversations and records can be deleted in Settings. - There is a daily limit on how many messages you can exchange with Omo. - Omo's replies are generated by AI and may not always be accurate. If you have been looking for an AI diary, chat journal, daily log or visual journaling app, tell Omo about your day and watch your memories form a tiny universe.

"A baby fox like a purple cloud, who loves the stars." Say it out loud — and a one-of-a-kind creature is born from your very words. ◆ Born from your words Describe a creature in a sentence, and Moonchi comes to life. Its shape, texture and colors follow your words, rendered in living, breathing real-time 3D. No sentence is ever the same — so no Moonchi is ever the same. ◆ A friend who remembers Moonchi remembers what you share. Yesterday's presentation, next week's trip, the little things you said you loved — they come back in tomorrow's morning greeting. ◆ Three beats a day In the morning, Moonchi greets you first. Through the day you feed, wash and tuck it in, and on good days it sets off on little adventures of its own. At night it returns with stories to tell and treasures it found along the way. ◆ The night general store Dress up your Moonchi with stardust — a star horn, a cloud-soft mane, a moonlit cape. Nothing on the shelf ever disappears; everything stays, for whenever you're ready. ◆ Our promises · Moonchi never dies. Away for a few days? It takes care of itself, and welcomes you back. · Its heart is not for sale. Bond, memory and growth come only from time spent together. · No rushing. No timers, no fear of missing out. · No auto-renewing subscriptions. Only what you want, when you want it. ◆ Good to know · Chatting and caring are free every day. Stardust (in-app purchase) unlocks longer story time and decorations. · Long-press any chat bubble to report inappropriate content instantly.
