Verdict
The clearest difference is review sentiment: PerfectLine at 88% against PATANAVI's 43%. PerfectLine also leads on update cadence (every 9 days vs every 3 weeks) and ratings volume (6 vs 1). PATANAVI's advantage is rating (5.0 vs 3.7) and ads (none vs shown). On price, in-app purchases, monetization model and device support 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. PATANAVI sells 2 in-app purchases, starting at $4.99 per month and PerfectLine sells 10 in-app purchases, starting at $9.90 per month. Whichever you choose, the download price is not the number that matters.
PATANAVI holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: PerfectLine has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of PATANAVI's written reviews are positive against 88% of PerfectLine's, so the app with the better star average is not the one people write more warmly about.
PATANAVI ships an update every 3 weeks, PerfectLine every 9 days. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
