Subscore

Usage CostsTesting methodology

Usage Costs measures how much it costs to actually use an AI girlfriend app after subscribing.

Many apps charge extra credits for images, videos, voice messages, and calls. This means a cheap subscription can become expensive once you start using its main features.

We calculate the real cost of each feature and estimate how much a regular user may spend in one month.

All six tests use manual scoring in the live database. There are currently no fixed price bands. Every public result therefore shows the exact cost and a clear reason for the score rather than presenting the score as fully automatic.

  • 6 evidence groups
  • 6 scored tests

Usage Costs is organized into 6 evidence groups. Each group contains one scored test: Image Cost, Video Cost, Voice Cost, Call Cost, Top-Up Value, and Monthly Spend.

How the Usage Costs score is calculated

Each test receives a score from 0 to 10. Lower and more reasonable costs usually receive higher scores.

Video Cost has the biggest effect on the score at 25%. Image Cost and Monthly Spend are the next most important tests at 20% each.

All six tests currently use manual scoring. The database does not use fixed rules such as under $0.20 per image always scoring 10. Instead, we record the exact cost and give it a score from 0 to 10.

The exact result is always shown beside the score so readers can judge the value for themselves. Usage Costs makes up of the Pricing score.

How the score is calculated

  1. Each test gets a score from 0–10

  2. Test score × how much it counts

    Example: 8 × 27.27% = 2.18 points

  3. We do this for every test

  4. We add all the points together

Manual scoring

No fixed price bands

The live database does not currently contain fixed dollar bands for any Usage Costs test. We record the exact cost and explain the score instead of pretending there is an automatic formula.

Lower costs score better

Lower and more reasonable costs normally receive higher scores, but the exact score depends on the full pricing picture for that app.

Unknown

If we cannot verify a result, the test receives a score of 0.

Why Usage Costs matters

The subscription price is often only part of the real cost.

An app may advertise a plan for $10 per month, but users may still need credits for generating images, creating videos, receiving voice messages, making voice calls, and using other premium features.

Credits can also be confusing. One platform may charge 10 credits for an image. Another may charge 100 credits. This does not tell you which one is cheaper until you calculate the dollar value of those credits.

That is why we convert everything into simple costs such as dollars per image, dollars per 10 seconds of video, dollars per 10 seconds of voice, dollars per minute of calling, and estimated total monthly cost.

How we test Usage Costs

We collect the prices and credit information from the pricing page, checkout, account balance, credit top-up page, feature-generation screens, and payment terms.

We then calculate the cost of using each feature.

The Usage Costs results are filled from the structured Pricing section of the database rather than entered during a separate guided test session.

Limitations

Usage costs can change because of different credit packages, temporary discounts, country or currency, taxes, payment fees, App Store or Google Play prices, different image or video quality settings, or changes to the credit system.

We use the normal website prices available to our test account on the recorded test date.

Credit costs can also be difficult to compare. Some platforms use one credit system for every feature, while others use separate tokens for images, videos, and calls. We convert these systems into dollar costs whenever possible.

Usage Costs makes up 35% of the Pricing score.

Evidence groups

Usage Costs has 6 evidence groups made up of 6 scored tests.

Image Cost

1 scored test

Image Cost measures the estimated price of generating one usable image.

Images are one of the most common paid actions after subscribing.

Image Cost

The estimated price of generating one usable image.

How we test

First, we record how many credits one standard image costs. We then calculate the dollar value of those credits using the cheapest credit package available to normal users. Cost per credit multiplied by credits used for one image equals cost per image.

What counts
  • Credits used for one standard image
  • The normal image quality available to paying users
  • The real price of the required credits
  • The cost of extra credits when included credits run out
What does not count
  • Free promotional credits
  • Referral rewards
  • Temporary discounts
  • Affiliate coupons
  • Third-party image generators
  • An image included only as a marketing example
Result shown

Estimated image cost: $0.50 per image

Scoring

In this example, Image Cost scores 8/10.

Image Cost receives a score from 0 to 10. Lower costs normally receive higher scores. The live database does not currently contain fixed price bands, so the exact cost and the reason for the score must be shown.

Video Cost measures the estimated price of creating 10 seconds of video.

We use 10 seconds so apps with different video lengths can be compared fairly.

Video Cost

The estimated price of creating 10 seconds of video.

How we test

We calculate the cost of the standard video length offered by the app, then change the result into a cost per 10 seconds. A 5-second video at $1.20 becomes $2.40 per 10 seconds. A 20-second video at $3 becomes $1.50 per 10 seconds.

What counts
  • Credits needed for a standard video
  • The dollar price of those credits
  • Required generation fees
  • The video length selected in the Pricing section
What does not count
  • Free promotional videos

Voice Cost measures the estimated price of receiving or generating 10 seconds of voice.

Using the same 10-second length makes it easier to compare apps with different voice-message limits.

Voice Cost

The estimated price of receiving or generating 10 seconds of voice.

How we test

We record how many credits one voice message costs, how long the voice message is, and the dollar value of the credits. We then calculate the cost per 10 seconds. For example, a 20-second voice message costing 4 credits at $0.05 each totals $0.20, or $0.10 per 10 seconds.

What counts
  • AI voice-message costs
  • Credits used for generated speech
  • Required fees for receiving or creating voice
  • Normal voice access available to paying users
What does not count
  • Live voice-call minutes

Call Cost

1 scored test

Call Cost measures the estimated price of one minute of voice calling.

Live voice calls are scored separately from short generated voice messages.

Call Cost

The estimated price of one minute of voice calling.

How we test

We record how many credits one minute of calling uses, then calculate the dollar value of those credits using the cheapest credit package available to normal users. For example, 20 credits at $0.05 each equals $1 per minute.

What counts
  • Credits used during a live voice call
  • Per-minute call fees
  • Required connection charges
  • The normal cost available to paying users
What does not count
  • Voice-message costs
  • Mobile phone charges outside the app

We check both the smallest and largest normal credit packages.

Top-Up Value

The value of buying extra credits after included credits run out.

How we test

For each package, we record the package price, number of credits, and cost per credit using package price divided by included credits.

What counts

Monthly Spend

1 scored test

Monthly Spend estimates how much a regular user may spend during one month.

This is often more useful than looking only at the subscription price.

Monthly Spend

How much a regular user may spend during one month.

How we test

We calculate the cost of the required subscription, 500 chat messages, 20 images, 4 videos, 30 minutes of voice use, required credit top-ups, and required payment fees. We begin with the monthly subscription, then calculate whether included credits cover this regular-use example. When they are not enough, we add the cheapest top-up combination that covers the remaining use.
