# Fixed Line vs FastCaller

The clearest difference is in-app purchases: Fixed Line at none against FastCaller's 4. Fixed Line also leads on ads (none vs shown) and rating (5.0 vs 4.7). FastCaller's advantage is ratings volume (15 vs 1). On price, update cadence and device support there is nothing between them.

Both are free to download. FastCaller sells 4 in-app purchases, starting at $0.99 per month. Fixed Line asks for nothing beyond the download.

Fixed Line holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: FastCaller has 15 ratings behind it against 1, so its average is the more settled of the two.
