# Gen Max 4D vs TopGuru

The clearest difference is rating: TopGuru at 3.5 against Gen Max 4D's 2.3. TopGuru also leads on update cadence (every 3 weeks vs every 26 months) and ratings volume (404 vs 3). Gen Max 4D's advantage is in-app purchases (none vs 29) and review sentiment (50% vs 29%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. TopGuru sells 20 in-app purchases, starting at $9.99 per month. Gen Max 4D asks for nothing beyond the download.

TopGuru holds the better App Store score, 3.5 against 2.3. That said, the two scores are not equally well evidenced: TopGuru has 404 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Gen Max 4D's written reviews are positive against 29% of TopGuru's, so the app with the better star average is not the one people write more warmly about.

Gen Max 4D ships an update every 26 months, TopGuru every 3 weeks. The most recent releases landed on September 12, 2026 and September 23, 2026 respectively.
