Currently 11% of my SAAS users will try the "taster" (no-sign-up) option, over signing up first. As of now no free tasters have converted to paid. Are taster users inherently less likely to convert to paid anyway? Wondering if it's worth having a taster option? It's quite a few flows to mange.

Yes! Bangin' Audio Recorder has reclaimed the no.2 keyword spot for the word "bangin'". ...if only the app was selling hammers, this would be really helpful! 🔨

Great to hear from an early sub that Screenodon is on the right track! "your app is the best option I found. I think it is a good balance of easy yet flexible." - User 02.

Metal view under SwiftUI overlays? Set presentsWithTransaction = true on the MTKView. By default Metal puts its frame on screen as soon as the GPU is done, while SwiftUI waits for the next Core Animation commit. That’s how overlays end up a frame behind the Metal content while it scrolls. Eeek.

Made a Meta Ads pipeline in Claude: 1. Establish strong MD SOT repo around the brand, positioning, assets etc... 2. Storyboard outline and script first. I tweak/approve. 3. Nano Banana 2 keyframes, then Kling or Veo clips. I approve the spend. 4. Eleven labs TTS 5. Original music written based on lifetime of joy, suffering, the human experience etc... 6. One JSON spec per ad, rendered in Remotion, audio to -14 LUFS About $3 to $7 of AI per ad

4 positive + unexpected benefits from my first 5 weeks back, and totally failing to grow, on X: 🧵

The virtual water-cooler: Solo founder life is akin to being on an isolated Arctic research post. It’s nice to have some connection to other remote outposts. Giving and receiving support on the journey is a win.

Human word alive and well (?): At least in my feed it appears that a good amount of the posts are human-made. AI writing has somewhat amplified what it means to write like a human.

The spec page for the new App Store header lists sizes and formats but no safe zone. So here they are: The Preview button on the Header tab can show the crop before it goes live.

4 months ago I sat down to register a domain name for my new project. Finding a name that resonates with what your product does AND is available is no easy task these days. So I registered.... ShotBliss dot com 🤔 ...and learnt the lesson: always run domain/company name ideas past my wife BEFORE registering. 😆

Apple’s screenshot spec now lists the iPhone Duo. From April 2027, Duo screenshots are required for apps built with the iOS 27.1 SDK or later. Submit them and your product page shows a badge saying the app is optimized for iPhone Duo.

How is anyone running Meta Ads for B2C subs!?!? 4 days into a Meta Ads experiment for iOS app: - $122 spend - CTR 14% - 8 installs @$15 each - 1 new monthly sub at $10 - 1 new annual trial start at $60 - $61 per trial start... eeek 🤔 Is this going to work? The algo really needs to get cheaper installs because the LTV still isn't justifying the CAC. Almost everyone who installed actually onboarded and signed up, which is encouraging.

Initially started the campaign with video ads only. Just added some image ad variants - perhaps this will help.
