# Standard Form Calculator vs PicSolve

The clearest difference is review sentiment: Standard Form Calculator at 100% against PicSolve's 39%. PicSolve's advantage is rating (4.5 vs 3.7) and ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Standard Form Calculator sells 1 one-off in-app purchase and PicSolve sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PicSolve holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: PicSolve has 7.5K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Standard Form Calculator's written reviews are positive against 39% of PicSolve's, so the app with the better star average is not the one people write more warmly about.

Standard Form Calculator ships an update every 8 months, PicSolve every 9 days. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
