# iPerf vs TOP

The clearest difference is review sentiment: TOP at 100% against iPerf's 42%. TOP also leads on rating (5.0 vs 4.2) and update cadence (every 2 weeks vs every 9 months). iPerf's advantage is ratings volume (19 vs 1). On ads, in-app purchases and device support there is nothing between them.

iPerf costs $1.99 and TOP $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

TOP holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: iPerf has 19 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 42% of iPerf's written reviews are positive against 100% of TOP's.

iPerf ships an update every 9 months, TOP every 2 weeks. The most recent releases landed on September 24, 2026 and September 8, 2026 respectively.
