Pay for what you use

Scores are estimates, and we say so
YouTube doesn’t publish how often a keyword is searched. Instead of inventing a number, Tube Gain scores competition and opportunity from the videos that actually rank: their views, age, speed and channel size.
| Diamonds | What it covers |
|---|---|
| 100 | 10 AI generations, or 20 keyword searches |
| 550 | 10% bonus |
| 1,200 | 20% bonus |
| 3,500 | 40% bonus: enough to unlock everything |
| Cost | Unlock (yours for good) |
| 250 | Premium tag pack (8 niches, e.g. Shorts Growth, Faceless Channels) |
| 400 | Unlimited custom tag sets |
| 300 | Competitor tracker |
| 150 | Colour theme |
Is Tube Gain made by YouTube?
No. Tube Gain is an independent app for YouTube creators. It reads public data through the official YouTube API and is not affiliated with YouTube or Google.
Does it need my YouTube password or account?
You sign in with Google, which is how your diamonds stay attached to you and not to one phone. That sign-in gives the app your name, email and picture only — never access to your YouTube account, your videos or your analytics. Tube Gain reads public videos and channels through the official API.
Why don’t you show search volume?
YouTube doesn’t publish search volumes, and apps that claim exact numbers are guessing. Tube Gain shows competition and opportunity scores worked out from the videos that actually rank, and labels them as estimates.
Is there a subscription?
No. You buy diamonds when you need them and spend them per use. Unlocks like tag packs, themes and the competitor tracker are yours for good.
What happens if a lookup fails?
Your diamonds come back automatically. If YouTube or the AI service is down, or a video turns out to be private, you are not charged.
I reinstalled the app. Where are my diamonds?
Sign in with the same Google account and they are there: balances live on our server, not on the phone. If something still looks wrong, open the support chat in the app, or write to tubegain.online@gmail.com with the account ID shown in Profile.
Your next video, better prepared.
