Pricing

One product or twelve — same Erdi.

What changes is how much we go and fetch for you. 14 days with everything switched on, no card.

Solo

You know where your numbers live. You just want them in one place.

€190 / year

€16 a month.

  • One project
  • Your deploys, incidents and purchases arrive on their own — GitHub, Sentry, RevenueCat and Vercel send them to Erdi
  • Send your own numbers — one line from your cron, your database, your script
  • Type in what no API has — an influencer fee, a newsletter slot, a podcast read
  • Look back as far as your data goes
  • Get told when a number moves
  • A public ship log — for a customer watching, or an audience following

1 projects, €9 for each one after that.

Up to twenty-five. More than that? Write to me.

Pro

You'd rather not go and get them yourself.

€390 / year

€33 a month.

  • Everything in Solo
  • Erdi goes and gets your ad spend and store numbers — Apple Search Ads and App Store Connect, connected once, then every day
  • See that spend broken down by country, campaign and keyword
  • Your ship log, without the ErdiKnows line

1 projects, €9 for each one after that.

Up to twenty-five. More than that? Write to me.

Studio

You're running a portfolio, or building for clients.

from €249 / month

ErdiKnows is offered to businesses only. Prices are net, plus VAT where applicable.

EU companies with a VAT ID are billed under reverse charge.

Nothing is charged until you choose a plan. Thirty days after that, fully refundable — no questions.

Included in every plan, including the trial.

Webhooks and the open endpoint

GitHub, Sentry, RevenueCat, Stripe and anything you can POST to a URL. Never counted, never capped — the more you send, the better the timeline reads.

Your numbers, exportable

CSV of everything, any time, on any plan. Nothing you put in becomes harder to get out.

Manual entries

Influencer fees, newsletter slots, a podcast read. No API has these. Type them in and they sit in the same column as Apple’s numbers.

What the price doesn't buy you

  • A reason. Erdi shows what happened around a change. It never tells you what caused it.
  • A comparison to other companies. Benchmarks need thirty independent products per group. Erdi compares you to your own history instead — sooner, and closer to the truth.
  • Attribution beyond Apple Ads. Apple reports which campaign brought which subscriber. No other channel does — an influencer or a newsletter leaves no trace Erdi could follow, so it stays a spend line, not a customer count.
  • Who your customers are. Apple reports age and gender as Low Volume for anything at this scale. That's Apple's limit, not ours — but the number would be empty either way, so it isn't here.

What happens when the trial ends and I don't subscribe?

The account goes quiet. Your webhooks keep arriving and your metric script keeps writing — you just can't open the views. Subscribe later and everything from the gap is there. Accounts that stay quiet for a year get a heads-up by mail before anything is deleted.

Do I need a card to start?

No. The trial starts the moment you connect your first source and ends by itself 14 days later. There's nothing to cancel.

Why is the yearly plan the one you're pushing?

Two reasons, and neither is a trick: it's cheaper, and it means I don't have to run a billing system yet. If you'd rather go month to month, that's what the toggle is for.

I have five apps. What does that cost?

Pro includes 1 project; each one after that is €9, up to twenty-five. Five apps is €75/month on Pro. Studio is not a fixed price — write to me if you need a portfolio for clients.

Do I have to connect Stripe or RevenueCat?

No, and the price doesn't change if you do. Revenue, unit costs and the funnel need a money source to say anything useful — but nothing in the pricing rewards or punishes connecting one.

Who is behind this?

One person in Berlin, trading as 52N34S Group. Support answers come from the same person who wrote the code. There's a DPA, a subprocessor list and a security page if your side needs them.

Connect one source. Your last months are on the axis tomorrow.

Erdi puts your releases, spend and revenue on one timeline. What you conclude from it is yours.
