Verdict
The clearest difference is price: A at Free against AL CHEM's $11.99. A also leads on update cadence (monthly vs every 4 months). AL CHEM's advantage is rating (5.0 vs 1.0) and ratings volume (8 vs 1). On ads and in-app purchases 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
A is free to download; AL CHEM costs $11.99 up front. AL CHEM sells 2 one-off in-app purchases and A sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
AL CHEM holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: AL CHEM has 8 ratings behind it against 1, so its average is the more settled of the two.
AL CHEM ships an update every 4 months, A monthly. The most recent releases landed on October 20, 2026 and October 24, 2026 respectively.
