Verdict

The call

The clearest difference is rating: Credible at 4.4 against Impromptu Topic Generator's 3.2. Credible also leads on update cadence (monthly vs every 26 months) and ratings volume (240 vs 5). Impromptu Topic Generator's advantage is in-app purchases (none vs 8) and ads (none vs shown). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Credible holds the better App Store score, 4.4 against 3.2. That said, the two scores are not equally well evidenced: Credible has 240 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 60% of Impromptu Topic Generator's written reviews are positive against 50% of Credible's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Impromptu Topic Generator ships an update every 26 months, Credible monthly. The most recent releases landed on November 2, 2026 and October 24, 2026 respectively.
