FOSS
Release apps source code or conduct and post the results of a 3rd party audit. It's sad to say but there's only 1 maybe 2 FOSS SMS/MMS apps and they don't have many features. I feel like you apps would be great candidates for open source. You offer your apps free of charge so it doesn't seem like you're trying to monetize them. If you change the licensing and released the source this would exponentially accelerate the entire of the open source SMS/MMS application market. The features offered by both Textra and Chomp are so far ahead of the current FOSS SMS/MMS apps available your source code could be the driving force to push other devs to offer features of same caliber. Your apps would instantly reign supreme and if you wanted to monetize you could offer the basic app for free and then keep the most desired features behind a pay wall as well as accept donations from your users. It's just a thought but QKSMS or Fossify SMS just aren't cutting it anymore. I would love to be able to use your apps. But, without being able to review the code for potential security risks I'm a bit apprehensive to use them.
Thank you for your time. I hope you honestly consider my suggestions today.
