# GUGA vs BBnotes

The clearest difference is review sentiment: BBnotes at 100% against GUGA's 70%. GUGA's advantage is rating (4.7 vs 4.4) and ratings volume (163 vs 8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. GUGA sells 3 one-off in-app purchases and BBnotes sells 8 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

GUGA holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: GUGA has 163 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 70% of GUGA's written reviews are positive against 100% of BBnotes's, so the app with the better star average is not the one people write more warmly about.

GUGA ships an update every 4 days, BBnotes every 3 days. The most recent releases landed on July 3, 2026 and September 13, 2026 respectively.
