# Kioki vs Hello Nabu

The clearest difference is review sentiment: Hello Nabu at 100% against Kioki's 33%. Hello Nabu also leads on ads (none vs shown) and monetization model (ad-supported vs free with in-app purchases). Kioki's advantage is rating (4.7 vs 4.3) and update cadence (every 5 days vs every 2 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Kioki sells 2 in-app purchases, starting at $9.99 per month and Hello Nabu sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

Kioki holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Kioki has 46 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 33% of Kioki's written reviews are positive against 100% of Hello Nabu's, so the app with the better star average is not the one people write more warmly about.

Kioki ships an update every 5 days, Hello Nabu every 2 weeks. Both last shipped on November 5, 2026.
