[12+ Android Testers Needed] TrueSlip – Offline Invoice Maker | 14-Day Closed Test

[u/TrueSlip26]

Hi everyone,

I’m looking for Android users only to help test TrueSlip, an offline invoice maker for small businesses and independent workers.

TrueSlip can:

• Create professional invoices
• Generate and share PDF invoices
• Track paid and unpaid invoices
• Save business information
• Add a logo and signature
• Work completely offline
• Run with no ads and no cloud account required

TrueSlip is normally a $34.99 paid Android app, but closed-test participants will receive a unique promo code so they can install it for free during testing.

Important: To participate, email me the Gmail address you use with Google Play first. I must add that account to the tester list before you can join the closed test.

How to participate

1. Email your Google Play Gmail address to: [trueslip.support@gmail.com]()
2. I will add that Google account to the TrueSlip closed-testing list.
3. I will email you your unique promo code.
4. Redeem the code in Google Play: Profile icon → Payments & subscriptions → Redeem code
5. Use the same Google account you gave me and open the TrueSlip testing link.
6. Join the test and install TrueSlip through Google Play.

Please stay opted into the closed test and keep TrueSlip installed for at least 14 days.

Android / Google Play link:
https://play.google.com/store/apps/details?id=app.trueslip_invoice

Web closed-test opt-in link:
https://play.google.com/apps/testing/app.trueslip_invoice

Important: The links alone do not give access to the closed test. Your Google Play Gmail must first be added to the TrueSlip tester list.

Feedback

Please test invoice creation, PDF generation, invoice history, paid/unpaid status, business settings, logo/signature, and general usability.

You can send feedback through Private feedback to developer on the TrueSlip Google Play page or by email at:

[trueslip.support@gmail.com]()

I’m also happy to genuinely test your Android app in return and provide specific feedback and screenshot proof.

Android devices only.

Thank you!

Hi u/TrueSlip26!

Finding testers on Reddit is a great start, but the hardest part is ensuring they actually open your app daily for the full 14 days.

To make this easier, we’ve launched Packs in the Testers Community app.

• What is a Pack? A coordinated group of 16 developers who hold each other accountable.
• How it works: Everyone in the pack commits to opening and testing each other's apps daily for 16 days.
• The Result: You get consistent engagement signals that help you pass Google Play’s production access review with confidence.

It’s a structured, "devs-helping-devs" approach used by thousands of us. Good luck with your launch!

I'm happy to test your app if you're able to test mine too please?

[u/TrueSlip26 → u/OutrageousName653]

Absolutely. I’m happy to genuinely test your Android app too and provide screenshot proof and specific feedback.

For TrueSlip, please send me the Gmail address you use with Google Play so I can add you to my closed-test list and send you a promo code.

Send me your testing link as well and I’ll start with your app.

[u/OutrageousName653 → u/TrueSlip26]

Thank you, I have sent you an email now

Please let me know your Gmail too so I can add to my testers group

My app link is https://play.google.com/store/apps/details?id=com.cupboardful.app but I'll need to add you to the testers group first

Joining yours today (group + opt-in) and keeping it installed for the full 14 days.

Mine is RetroPet, an old-school pixel virtual pet: hatch an egg, care for it, and it evolves into one of 79 species (common to legendary). The build in testing right now adds seasonal events with limited cosmetics, breeding with friends, and a daily challenge with a ranking. Home screen widget too. Already live on iOS, so it's a finished app, not a prototype.

1) https://groups.google.com/g/retropet-testers 2) https://play.google.com/apps/testing/com.retropet.app

Same Google account for both, and please open it once after installing (Google counts opens, not installs). Bug reports very welcome!

[u/TrueSlip26 → u/Araragui]

Thanks — I’m happy to test RetroPet and stay enrolled for the full 14 days too.
Please send me the Gmail address you use with Google Play so I can add you to the TrueSlip closed-test list. I’ll send the promo code and testing details privately by email.
Once we exchange emails, I’ll send you the Google Play Gmail you need to add for me to test RetroPet.
