Verdict
The clearest difference is review sentiment: Cube Algorithms X at 100% against Building Atoms and Isotopes's 33%. Cube Algorithms X also leads on rating (4.8 vs 3.5) and update cadence (every 3 months vs every 18 months). Building Atoms and Isotopes's advantage is price ($1.99 vs $5.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Building Atoms and Isotopes costs $1.99 and Cube Algorithms X $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Cube Algorithms X holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: Cube Algorithms X has 32 ratings behind it against 2, so its average is the more settled of the two.
