Hey everyone!
I'm a high school student who recently got into bioinformatics, and I’ve been building an Android app called DNA Companion — a lightweight tool to help with DNA sequence analysis and primer design.
What it does:
• Converts DNA sequences & generates complementary strands
• Flags invalid or non-DNA characters (great for catching copy-paste errors)
• Supports degenerate bases (e.g., M, R, Y – helpful for primer design)
• 100% offline – no internet, no ads, no data collection
• Save and export sequences easily
🧪 I'm running a closed paid beta and need at least 12 testers so I can release it publicly on Google Play:
• Price: $3.59 AUD (~$2.39 USD)
• Just keep the app installed for 14 days (you don’t have to use it daily — Google just requires this)
• Feedback is appreciated but totally optional!
How to test:
1️⃣ Join the tester group:
https://groups.google.com/g/companiondna-testers
2️⃣ Opt into the beta:
https://play.google.com/apps/testing/org.yourname.dnaconversion
3️⃣ Install the app from the Play Store link you’ll get after joining
Thanks so much if you give it a try! I’m still new to all this, so any support from this community means a lot
Feel free to DM me if you have questions or run into bugs!
