RostamVPN vs NetMaster

RostamVPN now does two jobs. It carries your traffic through a private tunnel, and it checks where that traffic is going. PROTECT MODE While the VPN is on, Protect Mode checks the places your phone connects to against our threat list. Known malware and phishing destinations are blocked before your phone reaches them. It looks at network destinations. It does not scan your phone, your photos or your files. - See every blocked destination, when it happened, and why it was flagged. - Turn on block profiles for ads and trackers, adult content, or whole countries and regions. - A traffic view shows where your phone connects, busiest first. - Ask a plain question about your own traffic and get a plain answer. - One switch on the Home screen turns all of it off. YOU AGREE BEFORE ANYTHING IS CHECKED Protect Mode explains what leaves your phone before it leaves. While the VPN is on, the destinations your phone connects to and a device identifier are sent to RostamVPN so they can be checked. They are used for that check. We keep no browsing history. You can decline and keep using the VPN, and you can turn Protect Mode off at any time on the Home screen. THE VPN - One tap. No account, no email address, no password. - Connects on Wi-Fi, cellular and public networks. - Recovers on its own when a connection drops, and finds another route if one stops working. - Choose which region you come out in, or let the app pick the fastest one that works. - No ads, anywhere in the app. WHAT IT COSTS Your first three days are free. After that, RostamVPN Premium is a subscription billed monthly or yearly, at the price shown in the app in your own currency before you confirm anything. In Iran, Russia, Cuba and Syria the app is free. No payment screen is shown, nothing is counted, and there is nothing to decline or dismiss. The app works this out by itself — you do not have to ask, prove anything, or enter a code. That is a standing decision rather than a promotion; subscribers elsewhere cover it. If the app is meant to be free where you are and it asks you to pay, tell us. We would rather fix it than take the money. NOTHING TO HAND OVER No account, no email, no phone number, no name. We do not keep a record of the sites you visit. There is no sign-up to undo and no profile to delete. Removing the app removes everything on your phone. Privacy Policy: https://www.rostam.app/en/privacy/ SUBSCRIPTION DETAILS Payment is charged to your Apple ID when you confirm. It renews automatically unless auto-renew is turned off at least 24 hours before the current period ends. Manage or cancel it in Settings > Apple ID > Subscriptions. The Terms of Use and the Privacy Policy are both inside the app, on the subscription screen, so you can read them without leaving the app and without waiting for a website to load. Lost Premium after changing phone? An account code restores it. It creates no account and asks nothing else about you. iPhone and iPad. Requires iOS 15.6 or later.

NetMaster helps explain slowdowns, instability, and intermittent dropouts without an account, ads, analytics, or tracking. RUN A COMPLETE NETWORK SCAN • Measure download and upload goodput with parallel HTTPS requests • See HTTPS latency, adjacent response-time variation, request failures, and a second latency vantage point • See confidence ranges and a p95 only when enough observations support it • Check direct UDP DNS response delivery across two providers, including bursts • Check latency under load and receive a bufferbloat grade • Compare everyday and first-time DNS response times • See the DNS transport observed for NetMaster’s measured request and compare resolver performance • Test real IPv4 and IPv6 reachability • Time the router hop and see whether added delay is local or farther upstream • Review public IP, ASN, egress region, TLS, HTTP, Wi-Fi security, captive-portal evidence, and tunnel indicators • Optionally install the bundled NetMaster Shortcut for connected iPhone Wi-Fi channel, standard, RSSI, noise, and RX/TX PHY rates — no compatible router or controller required • Watch live signal/noise, negotiated PHY rates, passive device traffic, and access-point changes • Compare the OS route gateway, Apple, Cloudflare, Google, and selected public-service latency graphs, rotating one probe at a time • Optionally select an M-Lab server for a separate single-flow route cross-check NARROW DOWN CONNECTION PROBLEMS Quick Diagnosis checks the path, router, internet, DNS, and responsiveness in sequence, then gives one likely explanation and a practical next step. INVESTIGATE INTERMITTENT DROPOUTS Run a 5-, 15-, or 30-minute monitor. On iOS 26, a user-started finite session can request lock-screen continuation; earlier versions must keep NetMaster visible. NetMaster records route changes, HTTPS heartbeats, gateway/DNS controls, IPv4/IPv6 evidence, latency changes, unknown gaps, and optional AP-roaming evidence. ESTIMATE ACTIVITY NEEDS Cautious assessments cover calls, 4K streaming, gaming, browsing, and uploads while naming the measured evidence and its limits. Protected history compares the same network over time, with a metrics-only mode. WATCH YOUR MAC FROM IPHONE Pair one iPhone to your Mac through private iCloud. See processor, memory, thermal, battery, and Mac traffic updates, 30-day history, eligible alerts, and PDF/CSV reports. Storage and low-storage findings remain visible only on the Mac. Remote speed tests require confirmation. BUILT FOR HONEST RESULTS A payload budget controls data use. Replenished parallel transfers target a stable window; when the cap ends a fast test too soon, the result is a lower bound, not a claimed maximum. Full-scan HTTPS timing is not ICMP ping; the separate live-latency board uses explicitly labeled ICMP echo. HTTPS adjacent response variation is not packet jitter; HTTPS request failures and UDP DNS response loss are not raw packet loss. PRIVACY BY DESIGN History stays in protected on-device storage. Optional Mac monitoring uses your private CloudKit database and no developer monitoring server. Reports leave only when you choose Share, with address redaction on by default. Important: Direct iOS app APIs omit exact radio values. The optional user-installed Shortcut uses Apple's Get Network Details action for connected RSSI, noise, channel, standard, and PHY rates; derived band can be ambiguous. Channel width, RF spectrum health, and cellular dBm are never invented. Wi-Fi identity needs permission. Balanced allows about 54.5 MB of throughput payload plus small requests and protocol overhead. Results are evidence, not proof that a router, carrier, VPN, or service is defective.
