Screen2Speech is the easiest way to get spoken audio from PDF files and text. Paste a link to a PDF file, upload a PDF from your Files, or paste text in. Then let the app read to you. Screen2Speech lets you pause and play your audio content as you need to. Feel free to navigate away from the app; the app will keep talking to you! Tip: if your iPhone is connected over Bluetooth to, for example your Mac laptop, then you can copy on your laptop and paste it directly in the app. Rest assured that Screen2Speech does not store any of your data. Screen2Speech supports the following languages: Arabic, Bulgarian, Bengali, Czech, Danish, German, Greek, English (US), English (UK), Spanish, Estonian, Finnish, French, Hebrew, Hindi, Croatian, Hungarian, Indonesian, Italian, Japanese, Kazakh, Korean, Lithuanian, Latvian, Marathi, Malay, Burmese, Norwegian, Dutch, Punjabi, Polish, Portuguese, Romanian, Russian, Sindhi, Slovak, Slovenian, Serbian, Swedish, Swahili, Tamil, Telugu, Thai, Turkish, Ukrainian, Urdu, Vietnamese, Cantonese, Yiddish, and Chinese.

Verdict
The clearest difference is update cadence: Crescent Keys at fortnightly against Screen2Speech's every 6 months. Crescent Keys also leads on iOS requirement (11.0 vs 16.4). On price, ads, in-app purchases and device support there is nothing between them.
