FT8 Decoder vs Vouch.io EVC
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
FT8 Decoder
This application decodes FT8 digital signals from amateur radio bands. It can process audio from external sources or directly from an SSB radio or SDR. The app also generates FT8 modulated audio for experimentation.
- Decodes FT8 8FSK modulated signals
- Processes external audio or SDR sound
- Supports standard callsigns and 13-character messages
- Generates FT8 message audio
- Experiment with sending and receiving FT8 audio

An FT8 decoder. FT8 is a weak signal digital mode, currently very popular in the amateur radio HF shortwave bands. The ft8d app allows decoding FT8 8FSK modulated signals contained in externally provided audio or sound from an SSB radio or SDR. The app supports Level 1 decoding of messages with standard callsigns or 13 character free text messages. The app can also generate standard FT8 message audio, so can be used to experiment with sending and receiving FT8 encoded and modulated audio. The app does NOT perform Auto-sequencing, or decode long hashed callsigns.
Vouch.io EVC
This app allows EV charger owners to securely access and manage their charging stations offline. It also enables owners to grant temporary or limited access to friends and family via AirDrop.
- Secure offline charger access
- Share access with friends/family
- Set time/usage limits for shared access
- Biometric and SMS validation
- NFC device enrollment
- BLE and peer-to-peer TLS connection

An Electric Vehicle (EV) charging application, working in conjunction with Vouch.io EVC hardware, that provides EV charge station owners secure offline access to their chargers and provides a secure and seamless method to share access to friends and family. For best results and experience, we recommend using iPhone 11 and later. The owner access is secured by first setting up the iPhone as a representative for the owner via SMS validation code, biometric check, and Vouch.io cryptographic proofs. The Vouch.io EVC hardware ownership is established during enrollment of a Vouch.io EVC device. The owner has a method where the device's NFC antenna is scanned to retrieve a unique identifier for that device, then the device is enrolled with the Vouch.io cloud to establish the owner's cryptographic proof over this device. Once established, the owner can connect offline via a secure BLE, peer 2 peer, TLS connection to the EVC unit. Once securely connected, the owner is able to charge a vehicle to the desired amount. Once charge is completed, the app is disconnected from the Vouch.io EVC. In addition to providing a secure method to connect and charge for the owner, the EVC app also provides a mechanism for sharing access to the owner's EV charger for friends and family. Sharing access to a friend or family member is done via Air Drop. The information shared has a deep link to the app so the receiving user can download, onboard (same as the owner), and use the application. The access to a specific EVC unit is also conveyed with the share allowing the friend or family user the same secure, cryptographic, offline access to the Vouch.io EVC enabled charging station. The application can apply limits to the share, for instance time or usage limits, providing full control for the owner over the owned EV charger. The application is an iOS native app, using BLE to communicate with the Vouch.io EVC devices and friend iPhone devices.

Verdict
The clearest difference is price: Vouch.io EVC at Free against FT8 Decoder's $1.99. Vouch.io EVC also leads on rating (5.0 vs 4.3) and update cadence (every 4 months vs every 18 months). FT8 Decoder's advantage is ratings volume (8 vs 2). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
