Test our apps before
anyone else can.
Every Android app we build goes through a closed test on real phones before it reaches Google Play. Testers install it, keep it for 14 days and tell us what breaks — and in return get free access to every paid app we release.

What testers get
You are doing us a favour, so the deal is meant to be worth your while.
Free access to paid apps
Anything we later charge for is free on your account — not a trial, not a discount.
Every build first
New features land on your phone weeks before the public Play listing sees them.
Your feedback ships
One tester message has changed a release more than once. Small list, real weight.
Nothing to pay
No fee, no subscription, no card, no ads pushed at you for taking part.
Real apps, not surveys
Downloaders, gaming tools and utilities people use every day — installed from Google Play.
Leave whenever
Uninstall and you are out. No lock-in, no account to close, no follow-up mail.
How it works
Four steps, and only the third one asks anything of you.
Send us your Play Store email
Use the form below — it has to be the Google account signed into the Play Store on the phone you will test on.
Accept the invite
We add you to the tester list and send back a private join link. One tap, then install from Google Play like any other app.
Keep it for 14 days
Google needs 12 testers running the app for 14 continuous days before it can go public. Uninstalling early can reset that clock for everyone, so leave it on the phone.
Tell us what broke
A screenshot or a single line is plenty. If nothing goes wrong, you do not have to send anything at all.
In testing right now
Five apps are on test right now. Tap one to open it on Google Play.
Riplox TT
Save any TikTok without the watermark, or pull its audio as MP3. Anyone can install this one — no invite needed.
Riplox IG
Share a reel, story or carousel from Instagram and it saves itself to your gallery. One link takes every video.
JFF Crosshair Pro
A crosshair overlay that sits on top of your game, with sizes, colours and profiles you can switch mid-match.
JFF Stylish Name
Turn your gamer name into stylish fonts and symbols, then copy it straight into the game.
Cipherly
Lock a message behind a password and send it anywhere. Only someone with the key can read it back.
Riplox TT is an open test — install it straight away. The other four are closed tests: "Join the test" only works once your email is on the list, so send the form below first, then join and install.
Apply for Android app testing
Fill this in and we will send your join link. Usually the same day.
Must be the account signed into the Play Store on your phone — a different address cannot open the tester link.
Only so we can reach you faster than email if a build needs a quick check.
Prefer email? hello@xniperbuilds.com
Your email is used for one thing: adding you to the Google Play tester list and sending the join link. It is not sold, not shared and not added to any mailing list — ask us and we will remove it.
Questions testers ask
Does testing cost anything?
No. Nothing to pay, no subscription, no card. The apps you test are free, and so is the programme.
Why do you need my Gmail address?
Google Play closed testing works by email. Your address goes on the tester list for the app, which is what makes the private install link work on your phone. It has to be the exact Google account signed into the Play Store on the device you will test on.
What does "free access to paid apps" mean?
When we release an app or a pro unlock that other people pay for, testers get it at no cost on the Google account they test with. It stays free for that account — it is not a trial and not a discount code.
Why 14 days?
Google requires an app to run a closed test with at least 12 testers for 14 continuous days before it can be published to everyone. If people uninstall early the clock can reset, which is why we ask you to leave it on the phone for the two weeks.
Do I have to write reports?
No. A screenshot or a one-line message when something looks wrong is plenty. If nothing breaks, you do not have to send anything at all.
Can I leave the programme?
Yes, any time. Uninstall the app and reply once to say you are out. There is no lock-in and nothing to cancel.
Will a test build damage my phone?
No. Test builds install from Google Play like any other app, run in their own sandbox and uninstall the same way. They are the same builds we run on our own phones.
Found a bug? Want a feature?
Tester or not — if one of our apps misbehaves, or you want it to do something it doesn't, tell us here.
Prefer email? hello@xniperbuilds.com
Reports go straight to us. Nothing is published, and an email address is only used to reply to you about this report.
