# 科学通用calculator vs 音频转文字

The clearest difference is in-app purchases: 科学通用calculator at none against 音频转文字's 4. 科学通用calculator also leads on ads (none vs shown) and iOS requirement (8.2 vs 15.0). 音频转文字's advantage is rating (4.6 vs 4.2). On price, review sentiment, ratings volume and device support there is nothing between them.

Both are free to download. 音频转文字 sells 4 one-off in-app purchases. 科学通用calculator asks for nothing beyond the download.

音频转文字 holds the better App Store score, 4.6 against 4.2. Both are backed by a comparable volume of ratings — 11 and 31 respectively.
