Built for the unexpected.

The laptop is back at your desk. The problem is right in front of you. BitAnvil puts practical IT tools on your Android phone, so you can investigate the connection, check the configuration and get on with the job.

Made for IT professionals, network engineers, MSP technicians and hands-on troubleshooters.

CHECK FROM WHERE YOU ARE
Run network checks directly from your device. Investigate reachable hosts on the network you are using, including internal hosts when your network or VPN allows it.

NETWORK TOOLS
• IP Calculator: work with IPv4 and IPv6 networks, masks and address ranges.
• Subnet Planner: split a network into equal subnets by count or host requirements.
• CIDR List Builder: merge IP addresses, ranges and CIDRs into compact allowlists or blocklists.
• DNS Lookup: query A, AAAA, MX, TXT, NS, SOA, CAA, SRV and PTR records using DNS-over-HTTPS.
• HTTP Headers: inspect response status, redirects, timing and security headers.
• Port Reference: find common service ports without digging through browser tabs.

SECURITY AND TEXT UTILITIES
Inspect TLS certificate trust, expiry, subject alternative names and certificate chains. Estimate password strength, decode JWT headers and claims, generate hashes, encode or decode Base64, test regular expressions and work with logs.

Offline calculators and text utilities keep working without a connection. Network checks need access to their targets. JWT decoding does not verify a token's signature.

START WITH THE CORE TOOLS
Use the core utilities plus HTTPS and FTP/FTPS connection tests. Pin frequently used tools, customize quick actions and revisit your 30 most recent saved results.

GO FURTHER WITH BITANVIL PRO
• Advanced connection tests for SMTP, IMAP, POP3, SSH, RDP, SMB, database ports, VPN gateways, DNS and custom TCP/TLS targets.
• Optional mail login tests over a trusted TLS connection.
• Bulk DNS lookups, certificate expiry checks and IP calculations for up to 100 entries per run.
• Export results and history as text, CSV or JSON.
• Save connection-test profiles for repeat visits.
• Generate CIDR output for iptables, nginx, Cisco ACLs and Windows Firewall.
• Unlimited history.

Pro is available through monthly or annual subscriptions, or a one-time lifetime purchase. Connection tests vary by protocol; a reachable port alone does not establish that an entire service is healthy.

YOUR WORK STAYS YOURS
No BitAnvil account required. No ads or analytics. History and settings stay on your device. Network tests contact the targets or DNS resolvers you select; purchases use Google Play.
