Verdict
Sensi and ViewLink both sit at 4.6 stars, but that hides the real split: 36% of Sensi's written reviews are positive against 0% of ViewLink's. Sensi also leads on update cadence (monthly vs every 6 months) and ratings volume (244K vs 20). ViewLink's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 16.0). On price, rating, 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. Neither carries in-app purchases, so what you see is what you pay.
ViewLink holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Sensi has 244K ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 36% of Sensi's written reviews are positive against 0% of ViewLink's, so the app with the better star average is not the one people write more warmly about.
Sensi ships an update monthly, ViewLink every 6 months. The most recent releases landed on October 16, 2026 and October 3, 2026 respectively.
