Verdict
The clearest difference is review sentiment: Nullschool at 100% against PredictCurrent's 57%. Nullschool also leads on rating (5.0 vs 4.5). PredictCurrent's advantage is ratings volume (255 vs 27). On price, update cadence, 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. PredictCurrent sells 5 in-app purchases, starting at $15.00 per month and Nullschool sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Nullschool holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: PredictCurrent has 255 ratings behind it against 27, so its average is the more settled of the two. Written reviews point the same way: 57% of PredictCurrent's written reviews are positive against 100% of Nullschool's.
Both ship on a similar rhythm, roughly monthly. Both last shipped on September 23, 2026.
