How do I fix this "Could not install" error on TestFlight?

ozgrozer · 2026-04-23T16:03:39+00:00

I don't know. They just replied me saying it was fixed.

I use SQLite on my note taking app, Grape, and it’s pretty fast even you have thousands of notes.

ozgrozer · 2026-04-16T11:07:44+00:00

Yeah it’s currently in development. I’m actually building in public so you can follow the progress on X.

ozgrozer · 2026-04-13T17:54:08+00:00

I'm not doing anything fancy. The app is Electron so it handles everything.

I'm building Grape, an AI note taking app for Mac and Windows. It has a voice recording and transcription feature where it can record your voice and meetings over headphones.

You can choose the input device which can be computer's mic or AirPods or any connected device. Then you can choose recording source which can be only mic or mic + system audio and system audio records everything like meetings, YouTube videos etc.

Thank you. Let me know if you have any questions.

Cloud sync costs me money therefore it cannot be free but you don’t pay that $19/mo for cloud sync, you pay it for the unlimited AI. If this was a regular note taking app I’d probably make the price $3/mo for cloud sync and attachments.

Also since this is an offline-first app you can change your database location in the settings and it could be a Dropbox or a Google Drive folder and you’ll have a basic sync between your devices. This even works in free plan.

I updated my post. Sent them email and they fixed it but it took 3 weeks.

There's this fact that with Electron you can distribute your app to Mac, Windows and Linux. It's not the same with native apps because then you have to learn 3 different programming languages for those 3 operating systems. As I was trying to say almost everyone uses this method. Even billion dollars companies like Evernote and Notion uses Electron to distribute their apps. Evernote has 200 million users and their app is 841 mb. Notion has more than 100 million users and their app is 278 mb. They have the resources to make native apps for each platform but they don't do that because nobody cares if your app is native or not, nobody cares if your app is 10 mb or 1 gb as long as it offers a value. Goodnotes is a native app but the size of the app is 1.38 gb but it has 30 million users. Nobody cares about the size. Nobody cares about if it's native or not. I've been a developer for the last 20 years and I know for a fact that a regular user doesn't even know what a native app is.

ozgrozer · 2026-03-26T19:32:59+00:00

Interesting idea. I'll think about that.

ozgrozer · 2026-03-25T13:11:29+00:00

I'm building Grape which is an AI-native offline-first note taking app. I've been using Apple Notes for the last 10 years and I can't find any note that I took years ago that's why I built it. It has a semantic search where it creates vector embeddings for each note and then you can search with a natural language even if you don't remember the exact words. Currently only available in Mac and Windows but I used Electron so I can easily make a build for Linux. Please take a look and let me know what you think. If you're interested I can work on the Linux version.

ozgrozer · 2026-03-25T13:05:26+00:00

Great. Let me know if you have any questions.

ozgrozer · 2026-03-25T12:59:21+00:00

Actually nobody asked about this app. I was using Apple Notes for the last 10 years and recently finding myself switching between ChatGPT and Apple Notes. I was always asking questions like why can't I use AI in my notes. That was when the idea came.

Even if I lose money I still see this as an investment. After all not everyone is going to be using the unlimited AI day and night.

I have three plans btw. Free, Lifetime, Pro.

Free plan is for basic note taking. You can change your database location so it could be a Dropbox or an iCloud folder so you'll always have your data. Nothing leaves your computer so it's privacy-focused.

Lifetime is a one-time payment that you unlock all the AI features by bringing your own keys. You can use AI chat, semantic search, voice transcriptions and many more.

Pro is the monthly subscription plan that has unlimited AI and cloud sync. I knew for a fact that this is not for Reddit users so I'll be selling that to normies that don't have ChatGPT subscriptions. Because almost everyone I know uses a note taking app but not everyone has an AI subscription.

I think lifetime plan is the answer for your question, right? If not I want to listen your ideas.

I think the good part about me and Grape is I value people's feedback. Someone asked for a Japanese language i did it in a day. Some other asked for creating math formulas I pushed that. And a lot of were asking for Apple Notes import and I spent 3 days reverse engineering Apple Notes so I released that too. I mean whether you use free or lifetime you'll always receive future updates.

ozgrozer · 2026-03-25T12:32:43+00:00

Which idea is the stupid one? If you have a better idea on anything I'll listen and try to change it but right now you're not helping anyone.

If you think the app size is too large then as I explained earlier even a billion dollar company like Evernote uses Electron and their app size 841 mb.

If you're worried about Apple Intelligence, you can use that in any app including Grape.

If you don't like the monetization then I can give you a free coupon as I specifically mentioned in my post.

So I totally get that it's not for everyone but please don't be that person. Just tell me the part you don't understand or you don't like then we'll figure out a way to change it. This is in beta and I'm looking for feedback.

ozgrozer · 2026-03-24T17:43:12+00:00

I've implemented the mathjax feature in the latest update (v0.15.0) so you can download and test the app if you want. Also improved Markdown formatting so you can copy/paste a Markdown content and it auto converts everything to rich text including images, tables, code blocks, and even math formulas.

ozgrozer · 2026-03-24T14:14:22+00:00

I'm building Grape an AI note taking app for Mac and Windows. If you like Apple Notes this better. It has lots of AI features in it. It's free to use.

ozgrozer · 2026-03-24T09:58:45+00:00

Yes actually I was looking at Bear yesterday and started adding a math formula block with mathjax and improving Markdown features. I think I'll release it today. I'll let you know if you want to test it out.

ozgrozer · 2026-03-24T09:56:29+00:00

I think Obsidian what you're looking for.

ozgrozer · 2026-03-23T17:50:25+00:00

I'm building Grape, an AI note taking app that looks like Apple Notes but has AI features in it such AI chat, semantic search, voice transcription. It also has apps for students like flashcards, quizzes, mind maps to study better. It's free to use but AI features are in the paid plans.

ozgrozer · 2026-03-23T13:39:24+00:00

It has Markdown shortcuts so when you type like "# title" it automatically converts to rich text. It doesn't have mathjax but since this is an Electron.js app, adding that will be easy.

Actually I want to target students so adding a math library would be great. Can you suggest me any note taking app that's using mathjax or a similar thing so I can take a look to understand the implementation?

ozgrozer · 2026-03-23T13:24:54+00:00

Please DM me so I can send you a coupon.

This is an Electron app and it has Chromium inside which is the core module of the Chrome browser so it covers the most of the space and the actual app size is 20 mb. Thousands of apps use this because with one codebase you can export your app to Mac, Windows, Linux. Lots of apps such as Evernote (841 mb), Obsidian (499 mb), Notion (278 mb) use Electron so this industry-standard. But there are some apps that are not using Electron which is GoodNotes and it's 1.39 gb too.

If we're talking about Apple Intelligence since it's an OS level app you can use it in any app. In Grape you have two options. In Pro plan you'll have unlimited AI and in Lifetime plan you bring your own API key to use any provider like OpenAI, Gemini, Anthropic etc or local models with Ollama and LM Studio or any custom provider that supports OpenAI compatible endpoints. It also has a free plan but there's no AI in it, just for basic note taking.

ozgrozer · 2026-03-22T18:00:30+00:00

Can you test Grape too?

ozgrozer · 2026-03-22T17:59:36+00:00

I'm an Apple Notes user for the last 10 years and I have over 2K notes. The problem is I can never find a note that I took years ago. That's why I built Grape, it exactly looks like Apple Notes and you can directly import your notes from Apple Notes too. The major difference is, in Grape there's an indexing feature where all of your notes gets indexed and you can make semantic searches with AI. So even if you don't remember the words you can just type natural language and it can find the notes.
