Verdict
The clearest difference is review sentiment: Functional Groups at 100% against Physics Equations and Terms's 0%. Functional Groups also leads on rating (4.9 vs 1.0) and ads (none vs shown). Physics Equations and Terms's advantage is monetization model (ad-supported vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement 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
Both are free to download. Functional Groups sells 1 one-off in-app purchase and Physics Equations and Terms sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Functional Groups holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: Functional Groups has 23 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Functional Groups's written reviews are positive against 0% of Physics Equations and Terms's.
Functional Groups ships an update every 4 months, Physics Equations and Terms every 20 months. The most recent releases landed on November 3, 2026 and November 12, 2026 respectively.
