Verdict

The call

The clearest difference is price: Bubl ABC at $2.99 against LetterSchool's $9.99. Bubl ABC also leads on review sentiment (67% vs 38%). LetterSchool's advantage is update cadence (every 7 months vs every 143 months) and rating (4.6 vs 4.2). On ads, in-app purchases, monetization model and device support there is nothing between them.

Bubl ABC costs $2.99 and LetterSchool $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

LetterSchool holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: LetterSchool has 340 ratings behind it against 41, so its average is the more settled of the two. Written reviews complicate that: 67% of Bubl ABC's written reviews are positive against 38% of LetterSchool's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Bubl ABC ships an update every 143 months, LetterSchool every 7 months. The most recent releases landed on September 22, 2026 and September 19, 2026 respectively.
