Reciprocal Android testing
Better testing starts
with both sides showing up.
TestDuo helps Android developers build reliable, reciprocal testing partnerships — one clear request, one shared routine, and a record of what each side has completed.
Reciprocal by designDevelopers test for each other — not into a void.
Evidence with contextDaily progress can be shared and reviewed inside the test.
Reputation that mattersConsistency is visible without turning collaboration into noise.
How TestDuo works
A shared testing loop, made easier to keep.
TestDuo is designed around a simple exchange: find a compatible developer, agree to test, keep a consistent routine, and make progress visible to the person doing the same for you.
Keep the day visible
Use the test timeline to see what each side still needs to complete and what is waiting for review.
Build trust over time
Evidence, decisions, and reputation help the next testing partnership start with more context.
The TestDuo approach
A testing exchange should not depend on memory, luck, or endless reminders.
TestDuo gives two developers a shared place to coordinate their own work. It does not promise store approval, downloads, rankings, or a particular testing outcome — it makes the collaboration itself clearer and easier to follow.
Built for responsible collaboration
Share carefully. Test fairly. Keep control of what you upload.
Only publish apps and upload evidence you are authorised to share. Do not include passwords, payment information, private keys, intimate content, or another person’s personal information unless you have a lawful right to do so and it is genuinely necessary.
Your app, your responsibility
Each publisher remains responsible for their own app, listing, test build, permissions, and compliance obligations.
People may see shared proof
Evidence and messages you share in a test are visible to the relevant test participant. Avoid uploading anything you would not want them to see.
Fair use protects everyone
We may limit, remove, or investigate activity that appears abusive, fraudulent, unsafe, or inconsistent with the service rules.
