The RF Tools App from HUBER+SUHNER AG is a useful tool, which shows the relation between RF specific values like impedance, wave length, return loss (VSWR) and signal delay including their conversion. On top of this, the RF Assembly Calculator provides an easy comparison of H+S RF cables and assemblies in different configurations and in different environments. It offers a straight access to technical specifications such as insertion loss and power rating. Above all, engineers and students will love this handy and helpful tool. Content Tools Reflection measurement (Return loss - VSWR) Frequency wavelength (Wavelength calculation) Signal delay (Signal delay - Dielectric constant - Velocity in % of speed of light) Impedance dimension (calculation of impedance of coaxial line) dB Calculator (dB Ratio / Watt - dBm) RF Assembly Calculator (comparison of up to three HUBER+SUHNER RF cables) Used formulas are explained in detail by meaningful pictures. Products Provides an overview of HUBER+SUHNER products such as cables, connectors, antennas, lightning protectors and passive components with the help of the product catalogues.

Verdict
The clearest difference is rating: GATTBrowser at 4.6 against RF Tools's 3.0. GATTBrowser also leads on update cadence (every 2 months vs every 14 months) and ratings volume (210 vs 3). On price, ads, in-app purchases and monetization model 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.
GATTBrowser holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: GATTBrowser has 210 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 60% of RF Tools's written reviews are positive against 70% of GATTBrowser's.
RF Tools ships an update every 14 months, GATTBrowser every 2 months. The most recent releases landed on June 9, 2026 and September 22, 2026 respectively.
