There is a shift happening in how AI companion apps charge you, and it is worth flagging because it changes the math on whether an app is worth it. The clean, predictable monthly subscription is slowly giving way to credit systems, and while that is not automatically a bad thing, it does mean the price on the landing page is increasingly not the price you actually pay.
What is actually changing
The older model was simple. You paid a flat fee, you got the app, done. The newer pattern, which more apps are reportedly moving toward, meters the expensive stuff, mainly image and video generation, through credits. You get a monthly allotment, and when it runs out you top up. On paper this is fairer, because heavy users cost these companies far more to serve than light ones.
Why the apps are doing it
Generating images and especially video is genuinely expensive to run at scale. A single flat fee that covers a light chatter and a power user equally does not work when one of them is generating hundreds of images a month. Credits let the app charge in rough proportion to what you consume. That logic is sound. The problem is what it does to the buyer’s experience.
The catch for users
The catch is that the headline number stops meaning much. An app can advertise a low monthly price, and then the features that made you want it in the first place quietly burn through your credit balance far faster than you expected. I see this most in the visual-heavy apps. In my OurDream review the video generation is a real differentiator, and it is also exactly where the budget disappears fastest. The same pattern shows up in my Candy AI review, where image generation is the main draw and the main cost.
This is not a reason to avoid these apps. It is a reason to go in with clear eyes about the effective monthly cost, which is usually higher than the sticker.
How to not overpay
The approach that has saved me the most money is boring and it works:
- Start on the free or entry tier. Never buy the largest credit pack before you know your own usage.
- Run one normal week. Use the app the way you actually would, not a cautious trial, and watch how fast the balance drops.
- Do the real math. Multiply your week out to a month. That number, not the headline plan, is what the app costs you.
- Only then commit. If the real cost is fair for the value, buy the bigger pack or the yearly plan. If it is not, move on.
The flip side
To be fair to the apps, some of the flat-plan options are genuinely good value, particularly the text-first and memory-first ones that do not lean on expensive generation. Those are where a simple subscription still makes sense, and where you can mostly ignore the credit-anxiety entirely. My best free AI girlfriend apps roundup is a good starting point if you want to keep spending low or zero while you figure out what you actually value.
Where this is heading
I expect the split to harden. Visual and video apps will lean further into credits because the economics push them there, and conversation-first apps will keep offering flat plans because they can afford to. The practical takeaway does not change: judge an app by what a normal month of your usage costs, not by the number on the ad. My main ranking factors real cost into every placement for exactly this reason.
