Verdict
The clearest difference is rating: Antenna Tools at 5.0 against RF Calculators's 3.0. Antenna Tools also leads on ratings volume (7 vs 1). RF Calculators's advantage is in-app purchases (none vs 1) and update cadence (every 4 days vs every 4 months). On price, ads, device support and iOS requirement 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. Antenna Tools sells 1 one-off in-app purchase. RF Calculators asks for nothing beyond the download.
Antenna Tools holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: Antenna Tools has 7 ratings behind it against 1, so its average is the more settled of the two.
RF Calculators ships an update every 4 days, Antenna Tools every 4 months. The most recent releases landed on September 24, 2026 and October 16, 2026 respectively.
