Verdict
The clearest difference is price: DayLight at Free against TornadoSpy's $1.99. DayLight also leads on rating (4.6 vs 3.8) and ratings volume (218 vs 12). TornadoSpy's advantage is review sentiment (69% vs 45%) and chart position (#83 vs unranked). On update cadence, ads, in-app purchases 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
DayLight is free to download; TornadoSpy costs $1.99 up front. TornadoSpy sells 2 one-off in-app purchases and DayLight sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
DayLight holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: DayLight has 218 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 69% of TornadoSpy's written reviews are positive against 45% of DayLight's, so the app with the better star average is not the one people write more warmly about.
TornadoSpy ships an update every 2 months, DayLight every 6 weeks. Both last shipped on October 21, 2026.
