Verdict

The call

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.

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

AL CHEM ships an update every 4 months, A monthly. The most recent releases landed on October 20, 2026 and October 24, 2026 respectively.
