Subi vs Appstle
Appstle charges a flat monthly fee with no transaction fee at all. Subi charges a lower monthly fee plus a percentage. On the monthly bill alone, Appstle is cheaper at every volume their published plans cover. The question is what happens when you outgrow that coverage.
The short version
Appstle's published ladder stops at $100,000 a month of subscription revenue. Past that you negotiate. Subi's ladder has no revenue cap.
Appstle gives 14 days to trial; we give 7 plus a 3-month money-back guarantee. Both are month to month.
The trade-off is straightforward: a lower monthly bill now against a pricing structure that does not cap out as you grow.
What you would actually pay
Monthly cost at different volumes of subscription revenue processed, each on the plan that fits that volume. Subi figures from our own billing configuration; Appstle figures from their public App Store listing. Both checked 1 September 2026.

Where Appstle is the better choice
We would rather you pick correctly than pick us.
- →Your monthly bill is what matters most and your subscription revenue is under $100,000 a month. Appstle's flat tiers with no transaction fee are cheaper at every volume in the table above.
- →You want a longer trial window. 14 days beats our 7, even with the money-back guarantee behind it.
- →You are already running Appstle and it is working. Migration is real work and inertia is a legitimate answer.
Where Subi is the better choice
The cases where the terms point our way even when the table does not.
- ✓Your subscription revenue is approaching or past $100,000 a month and you want pricing that scales without a negotiation.
- ✓You want a 3-month money-back guarantee on top of the trial. If it does not work out in the first three months, you get your money back.
- ✓You want subscriptions, memberships and bundles from one app rather than assembling them.
If you do decide to move
Subscription migration is not a CSV import. Existing contracts have to keep billing on their own schedules, with their own discounts, without asking your customers to re-enter anything.
Talk to us first with your numbers. We will tell you which plan fits and what it will cost.
We map your existing plans, discounts and billing dates before anything moves.
Contracts transfer with their schedules intact, subscribers do not re-subscribe and do not re-enter payment details.
We stay on it through the first billing cycle, which is the one where problems actually surface.
Questions merchants ask
Will my subscribers have to sign up again?
No. Contracts move with their existing billing dates and discounts. Asking subscribers to re-enter payment details is how a migration loses customers, so the process is built to avoid it.
Is Subi cheaper than Appstle?
No. At every volume in the table above, Appstle's flat tiers are cheaper. Subi's advantage is not on the monthly bill but on the pricing structure: our ladder has no revenue ceiling, and we include a 3-month money-back guarantee.
What happens when I pass $100,000 a month on Appstle?
Their listing says to contact them for Enterprise or API pricing. We do not know what those terms are because they are not published. Subi's Subi Plus plan covers that volume at $479 plus 0.40%, no negotiation needed.
