# Call Recorder・Voice Memos Pro vs iSign

The clearest difference is review sentiment: iSign at 100% against Call Recorder・Voice Memos Pro's 26%. iSign also leads on monetization model (free with in-app purchases vs subscription) and rating (5.0 vs 4.5). Call Recorder・Voice Memos Pro's advantage is ratings volume (181 vs 1) and iOS requirement (16.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Call Recorder・Voice Memos Pro sells 4 in-app purchases, starting at $5.99 per 7 days and iSign sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
