Read full description

MorseCipher is a Utility app that works completely offline. The app has the following features: 1. Allows users to translate any alphanumeric text to and from Morsecode (International). 2. Allows sharing Morse encoded messages either as a text via the iOS message app as an SMS or iMessage. 3. Provides option to play and download the Morse encoded message as a standard Morsecode audio (short/long beeps). 4. The Downloaded audio file can then be shared to another user for decoding in the app or using any online Morsecode audio decoding tools. The app also has an advanced mode that provides the following features: 1. Allows a pair of users to create a matching randomised cipher key secret, using a key exchange protocol. 2. This cipher key then allows the pair of users to scramble/unscramble any body of text e.g. confidential information which they can share securely with one another. 3. The app allows sharing the scrambled messages either using copy/paste commands or directly linking to the iOS message app to send the message as a standard SMS or iMessage to the recipients’ contact number. 4. Provides option to play and download the Morsecode "encrypted" message as a standard Morsecode audio (short/long beeps). 5. This Morsecode audio file is named morseoutput.wav, is downloaded and saved to the users Documents folder. 6. The downloaded Morsecode audio file can then be shared to the other user that has the matching cipher key for unscrambling in the app. Note that the Morsecode audio file has to be manually transcribed by the recipient into Morsecode text format before using the app to translate. Note that to provide extra layers of security, once a message is scrambled, it can only be unscrambled in the app on the device of either one of the users that generated the cipher key used to scramble the original message, and only during an active key-exchange session.  If the key-exchange session is terminated either by closing the app or clicking the reset button in the Cipher Keygen tab in advanced mode on both users devices, then the message can never be unscrambled, even using the app and the cipher key on another device, or using online Morsecode decoding tools. This is done so as to provide a high-level of security for confidential information that is scrambled/unscrambled using the app. Lastly to reiterate, this app is a Utility tool that works completely offline and does not connect to the internet. You are responsible for sharing any Morse-encoded or scrambled message you generate to the recipient using available sharing tools as mentioned above. All necessary caution must be taken when using the app particularly for encoding/scrambling sensitive/confidential information.

Sound Amplifier picks up the voices and sounds around you with your phone's microphone and plays them into your earphones in real time — so a soft-spoken friend, the TV across the room or a lecture from the back row comes through more clearly. Missed what someone just said? Tap Replay last 10s to hear the last 10 seconds again. Want the sound shaped for your own ears? Take the short Hearing Test and a personal EQ is built from your answers. Please note: Sound Amplifier is an everyday assistive listening tool. It is not a medical hearing aid and it does not diagnose hearing loss. LISTEN • Live amplification from 0 to +40 dB, with a live level meter • Replay the last 10 seconds — kept in memory only and cleared when you stop • Voice leveller that evens out loud and soft voices automatically • Noise reduction that cuts low rumble from air conditioning, traffic and wind TUNE • 3-band equalizer: bass, mid and treble, each ±12 dB • Presets for Speech, Music, Outdoor and Flat • A Personal preset created from your Hearing Test • Left/right balance for when one ear needs more HEARING TEST • Soft tones at 250, 500, 1,000, 2,000, 4,000 and 6,000 Hz, one ear at a time • Turn the result into a personal EQ with one tap • Hearing over time: compare later tests with your first one (changes under 10 dB are shown as no change) • Earphones or headphones are required, because each ear is tested separately MY SETUPS • Save up to 8 named setups — TV, restaurant, lecture — and bring one back with a tap SAFETY • A safety limiter caps loud peaks at a level you choose (-18 to 0 dBFS) • The app will not amplify through the phone's own speaker, where the microphone would pick the sound up again and howl • If your earphones disconnect, amplifying stops and a card explains why; reconnect them and tap Resume GOOD FOR • TV dialogue without turning the room volume up for everyone • Conversations in cafés, restaurants and family dinners • Lectures, sermons, meetings and guided tours • Birdsong and quiet sounds on a walk Tips: start with low amplification and raise it slowly. Wired earphones have the shortest delay; Bluetooth earphones work too but add a little lag. If you are worried about your hearing, please talk to a hearing professional.
