# Solves vs Calculator +ㅤ

The clearest difference is review sentiment: Solves at 91% against Calculator +ㅤ's 46%. Solves also leads on monetization model (free with in-app purchases vs subscription) and ads (none vs shown). Calculator +ㅤ's advantage is ratings volume (4.5K vs 381). On price, update cadence, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Solves sells 6 one-off in-app purchases and Calculator +ㅤ sells 6 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Solves holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Calculator +ㅤ has 4.5K ratings behind it against 381, so its average is the more settled of the two. Written reviews point the same way: 91% of Solves's written reviews are positive against 46% of Calculator +ㅤ's.

Solves ships an update every 3 weeks, Calculator +ㅤ fortnightly. The most recent releases landed on September 19, 2026 and September 23, 2026 respectively.
