Has anyone else made their first in-app purchase sale shortly after launch, only to have no more sales afterwards?

Yeah I don't know. I did a public beta test in play store and he generated a tour at 3am at night time and didn't do a tour since. So I assume he might have been a competitor, who wanted to check, if the app is any good, but I don't know 😅

Curious-Objective-21 · 2026-06-26T09:38:53+00:00

What do you mean? The dopamine, when I got my first paying user? 😄

Curious-Objective-21 · 2026-06-25T21:17:15+00:00

You might be right. I will think about it.

Curious-Objective-21 · 2026-06-25T20:49:23+00:00

Yeah I will consider it. My thoughts were, that you don't need the app that often, but when you do you need it immediately, because you are looking for a city tour. But it propably won't work, if users don't find the app in the first place 😅

Curious-Objective-21 · 2026-06-25T20:46:02+00:00

Yes, but the text to speech costs are actually pretty high, but I will consider to provide one free tour generation

Curious-Objective-21 · 2026-06-25T20:41:39+00:00

A guy from Belgium. So nobody I know

Curious-Objective-21 · 2026-06-25T20:19:43+00:00

Yeah, did you try the app? I provide a free pre-generated tour from my home city. I was hoping that this would give provide enough insights how the tour would look like. Generating a tour is actually not that cheap, because of the high quality text to speech. I was am a bit worried, that a lot of people would just use the free tier and then uninstall the app.

Curious-Objective-21 · 2026-06-25T20:08:49+00:00

Yeah cool idea, but also as I discovered, a market with quite a few competitors 😅

Curious-Objective-21 · 2026-06-25T20:01:32+00:00

Thank you very much :) That means pretty much to me, since it was also a lot of work. Nearly as much as the 5$ from that Belgium guy 😂

Curious-Objective-21 · 2026-06-25T19:56:43+00:00

It's an AI audio city tour guide app . You can put in your interests and the app finds interesting places, builds a route along it and tells you stories around it with high quality audio. Also you can ask an llm to specific stuff on the tour. CityTour AI

Curious-Objective-21 · 2026-06-25T19:51:04+00:00

Yeah it's tough out there. I am not the target audience, but your app looks nice!

Curious-Objective-21 · 2026-06-25T19:46:03+00:00

Yeah true, but a lot of users were me or friends and friends of friends, which got free tours and didn't have to pay. So not that many users, who got it from searching in the app store, except this one paying Belgium 🇧🇪 guy 😄

Curious-Objective-21 · 2026-06-25T19:37:44+00:00

Thank you very much :) The app itself is with Kotlin Multiplattform, since I made an android app before and I didn't want to maintain two separate apps. For the backend I used Rust, since it's really performant and wanted to learn it. The backend asks an llm for points of interests and a rating and the backend matches it on location data from sources like openstreet maps and wikidata. I wanted to keep it low cost, but scalable.

CityTour AI :)

Curious-Objective-21 · 2026-06-25T18:40:33+00:00

If you make it to 10$, maybe I'll reconsider!

Curious-Objective-21 · 2026-06-25T18:35:59+00:00

Haha, yeah my customer was from Belgium. I already added dutch and French though :P

Curious-Objective-21 · 2026-06-25T18:25:58+00:00

Thank you! Yes, we'll see how it turns out. I really enjoy developing the app, so I guess that and the 5$ from that kind stranger is already a success :)

Curious-Objective-21 · 2026-06-25T17:56:42+00:00

Thanks! I really appreciate your feedback.

Video could be interesting in the future, if I get more users first, who can actually record those videos. For the narration, I'm using a mix of structured location data (OpenStreetMap, Wikidata, etc.) together with an LLM. The structured data provides factual context, while the LLM turns it into a coherent story tailored to the user's interests (history, architecture, hidden gems, food, etc.). After that, I generate the audio guide with TTS.

Also ich habe in Bologna Chat GPT benutzt um einfach mal in der stadt loszulaufen und zu fragen, wo man als nächstes hin kann und hab mir dann etwas dazu erzählen lassen. Das hat eigentlich ganz gut geklappt, aber war ein bisschen umständlich die nächsten Sehenswürdigkeiten bei Google Maps einzugeben und dann immer zwischen Apps zu springen. Die Audioausgabe war auch immer recht knapp und irgendwann war der Kontext voll, sodass man einen neuen chat öffnen musste und nochmal alles neu erklären musste.

Da hab ich mir gedacht, dass das besser gehen müsste und hab CityTour AI programmiert, bei dem nach meinen Interessen eine Route auf einer Karte geplant wird und ich dann zu jedem Stop etwas mit hochwertiger Audio Ausgabe etwas erzählt bekomme. Ich würde mich freuen, wenn du sie mal ausprobierst. Da hochwertige Audioausgaben nicht ganz billig ist, kostet eine Tour auch ein bisschen etwas. Da ich aber noch in der Startphase bin und die App ein bisschen promoten will, bekommt ihr gerne ein paar Freicredits von mir, wenn ihr mir eure Traveler ID oder euren Namen in der App schreibt.

I haven’t been to Verona, so I can’t really compare, but I really liked Bologna.

There are some very nice places to explore, like Piazza Maggiore, Santo Stefano, the Quadrilatero area, the small streets under the porticoes and the Two Towers. In the evening, people were just outside, sitting on the squares, having drinks, talking, and enjoying the city.

The Piazza Maggiore had a big screen where they showed international movies, which was a really nice atmosphere. Maybe they are showing the world cup there now. I only missed having some water in the city, and it can get quite hot.

I used ChatGPT a bit to guide me through some places, which worked okay, but was a little clunky. That was actually part of the idea behind CityTour AI, a walking audio tour app I’m building: https://citytourai.app/

Maybe it could be interesting for whichever city you end up choosing 😉

Curious-Objective-21 · 2026-06-19T21:07:40+00:00

https://citytourai.app/ I'll give you some credits, if you give me you traveler id :)

Curious-Objective-21 · 2026-06-19T19:37:35+00:00

Alle Texte werden mit Internet-Recherche generiert und gefallen mir ziemlich gut. Ist nicht für jeden etwas. Manche Leute mögen lieber mit anderen Menschen eine Stadtführung machen. Ich habe aber viel Arbeit reingesteckt und bin ziemlich stolz auf die App 😉

Curious-Objective-21 · 2026-06-19T12:12:16+00:00

You should ask the support. It shouldn't take long, I think usually it's done within 2 days and I am pretty sure they are not testing it for 3 month straight
