This is how I’m going to grow my app to $100K/mo (and here’s why I’ll succeed): there are 3 content pillars: 1. Organic → will run 3 tiktok accounts → post 3-8x/day this will be my main focus until i’m able to reinvest in ads 2. Ads i will only start doing ads when i have the budget of running them for 30-45 days but also, not a lot of people know about apple ads you get $100 in credits to run ASA on the app store the only thing I gotta do is give Selfdrive (from Superapp AI) my app and it does all the work 3. UGC creators this is the hardest one you need: → high budget → time to talk with every creator and manage them → get ready for 30% of posts to flop the best way to do this is hire another person to manage it the worst method if you’re just starting out. ───────────────────────────── now, why will I succeed? i’ve signed an agreement with myself that I have to hit this goal by the end of the year else, i would have to give up and start all over again. the challenge has started.
Day 21 of building my app to $100K/mo These last few days have been insane: • got a new app idea • built 70% of it (with Superapp AI) • already made the marketing plan This is one that I’ll build in silence, because the competition isn’t very high (btw the whole marketing will be made by ai) In the next few days I’m also receiving the phone to start marketing in the US

imagine using real ugc when wan 3.0 prime exists $0.15 for a 5s video here’s what it made for me:
🤖 Made with AI
imagine paying $2k every month for UGC & influencers while this exists. wan 3.0 prime. $0.20 for a 10s video. trust me drop your overpaid influencers.

if you don't apply this paywall, you're NGMI
Did I just create the most cracked paywall ever?

Quittr was recently banned from the app store and it was only their fault. More than 600K user data was leaked because their backend sucked Before going live, always check for weak points So you don’t end up losing a $200K/mo app…
quittrr is gone too

You can now make Retention Messages inside the App Store Everyone should activate this now, it will boost your conversion by a lot
IT’S LIVE! You can now configure Retention Messages directly in App Store Connect No more closed beta, no need to register, no need to build on Apple’s Retention Messaging API, and no need to use @RevenueCat’s Retention Messaging feature You probably still want to, though: The thing that’s available to everyone *right now* is an image and text, shown to subscribers as they’re about to cancel, as well as offers per subscription <- This will increase retention. Guaranteed But if you want to customize what message you show to who, want to set up retention offers (discounts, plan switches, etc) for specific segments of users, and increase retention EVEN FURTHER, You still need to request access to the API, and our Retention Messaging feature will not only allow you to configure those messages and offers, but also allow you to experiment with the single best retention mechanic Apple has ever provider developers with So, 1. Go set up your retention messaging in App Store Connect *now* 2. Request access to the API 3. Get to experimenting and improving retention via RevenueCat

he’s right, I’ve just made a video in the same style only using Opus 5.5 here’s the prompt I used: “Make me a video just like in ReferenceVideo1, but for another mistake begginers make. It should be 20-30s. Add a male narrator, tiktok engaging style. Mantain the exact same style as ReferenceVideo1, only changing the idea behind the video” this is what it generated 👇
Holy F*CK this app niche is a disgusting money glitch not a single video under 1M views Zutobi a driving test app is making $600k/mo and the marketing is 100% automatable. → 119.2M Views on one video → 1M Followers do you get it goy? This is literally 1 of the most untapped app niches rn → make a driving app → automate this format with claude → start printing listen mf, you better follow me if im giving out this much value for free.

this just tells you everything you have to know about "celebrities" and how they work (and he's probably not the first to be treated the same)
I made Clavicular's looksmaxing app. But I haven't been paid a single dollar. We hit $55k MRR on day one. Top 10 on the App Store. I was promised 5% of revenue. Instead, I spent $500 of my own money. Might've just been scammed? Here's what happened: • I built a prototype in a few hours. • Spent a few days preparing for launch under a tight deadline with no real product direction. • Called in a favor from @BrettFromDJ for the original app icon (Favors from big people in this space aren't something I want to waste) • Figured i'd wait roughly 3 months for Apple's payout, no biggie. I willingly wired everything up to his bank, the way a trustworthy dev would. • After launch, I worked tirelessly handling support, reviews, bug fixes, and his manager's requests, including "capture all the data" (don't worry, I did maintain proper security rules) • Spent $500 of my own money on AI design tokens and App Store screenshots. The biggest battle was getting them to pay for a designer while rejecting AI designs too. Despite the success and momentum, they wouldn't invest a dime. Not in design, not in me, or in resources to build what the app needed. Eventually, another team member made a worse app icon and promised mockups that never came. Then they canceled the Firebase credit card without telling me, breaking the entire app lmao. Users churned, momentum died, and a massive opportunity fell apart. The app has generated around $30k in lifetime revenue. After days of damage control and work, all I asked for was $1,500. Despite never paying me, they recently asked me to rebuild the app into something entirely new. The feature set was exponentially more complex, rivaling products from billion-dollar companies. "Think you could do it this week. It seems pretty simple bro" Again, no designs, no spec, no payment. I asked them to provide those first. Still waiting. Turns out building an app isn't that easy. I've since been removed from App Store Connect. Still no payment. I don't know whether it's Clav or his manager. I just know nobody's made paying me a priority. I thought we were building a self-improvement platform that could dominate the app space. Instead, we squandered a top 10 launch and an opportunity most developers would kill for. Generational fumble.

this AI video cost me $0.50 & i didn't have to hire an influencer, write a complicated prompt or even film anything. i literally cloned an existing video with a completely different AI character. save the entire workflow: 1. find a viral tiktok you want to recreate 2. get a picture of the character you want to replace the original person with 3. use wan 3.0 prime on kie and upload both the video and the character image 4. use this exact prompt (save for later): “Recreate Video1 exactly, replacing only the original character with Image1. Strictly preserve 100% of Image1's face, hair, body, clothing and details. Match Video1's movements, expressions, camera angles, framing, lighting, background, timing and pacing. Seamless, photorealistic character replacement. No other changes.” 1. for “Image1”, attach the picture of your character 2. for “Video1”, attach the original video you want to clone 3. generate your video. that's literally it. no complicated prompts. no filming. no paying influencers $2k/month. just a video + a picture + one prompt. look at what wan 3.0 made for me:
if you want to clone any video with a different character, look at this. you don’t need AI to analyze your video and write a complicated prompt. you literally just need this (save for later): “Recreate Video1 exactly, replacing only the original character with Image1. Strictly preserve 100% of Image1's face, hair, body, clothing and details. Match Video1's movements, expressions, camera angles, framing, lighting, background, timing and pacing. Seamless, photorealistic character replacement. No other changes.” for “Image1”, attach a picture of the character you want in the video. for “Video1”, attach the video you want to clone. that's it. look at what seedance 2.5 made for me:

everyone is promoting this while i just made a game like that with Opus 5.5 in one prompt
Mobile game ads never look like the real game. Now you can turn a viral ad into a full mobile game. > Drop a gameplay video, a screenshot or a prompt > Build a mobile game with viral mechanics > Turn it into a playable ad on the Enterprise plan Higgsfield Playable is live now.

Day 1 of choosing a random app and making their marketing videos Today we have: Clap Finder - Anti Lost Here’s what I did: • I took a viral silence ugc video • Found one of the weird viral characters • Used my cloning prompt (from the last post) Here’s the final result: Which app should I do next?
Fun and useful app idea: Clap to find the phone $28k MRR only with Meta ads (data is from appkittie.com)

i was today years old when i realised claude can get your app on the iphone duo
Without exaggeration: Anthropic has done the most amazing job adapting Claude for the iPhone Duo, and I'm blown away by how good it looks. Now all I need is my iPhone Duo delivery. Kudos @AnthropicAI
