Verdict
The clearest difference is monetization model: Second Line Calling/Texting at free with in-app purchases against WiFi Calling App's subscription. Second Line Calling/Texting also leads on ratings volume (2K vs 190). WiFi Calling App's advantage is rating (4.6 vs 4.2) and update cadence (every 9 days vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. WiFi Calling App sells 11 in-app purchases, starting at $2.99 per 7 days and Second Line Calling/Texting sells 8 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
WiFi Calling App holds the better App Store score, 4.6 against 4.2.
