High-quality on-device transcription. Easily convert speech to text from meetings, lectures, and more. The transcription is powered by OpenAI's Whisper running locally on your device. Nothing leaves your device. You can export the transcription as subtitles too. It has a word-replacement feature to let you automatically fix common mistakes. Aiko favors accuracy over speed. It does not do live transcription while recording. It does not currently have speaker detection. Try the trial first. See website. Note: Sharing from Voice Memos on iOS 26 does not work because of a iOS 26 bug outside of my control. Supports audio in 100 different languages: Afrikaans, Albanian, Amharic, Arabic, Armenian, Assamese, Azerbaijani, Bangla, Bashkir, Basque, Belarusian, Bosnian, Breton, Bulgarian, Burmese, Catalan, Chinese, Croatian, Czech, Danish, Dutch, English, Estonian, Faroese, Finnish, French, Galician, Georgian, German, Greek, Gujarati, Haitian Creole, Hausa, Hawaiian, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Italian, Japanese, Javanese, Kannada, Kazakh, Khmer, Korean, Lao, Latin, Latvian, Lingala, Lithuanian, Luxembourgish, Macedonian, Malagasy, Malay, Malayalam, Maltese, Marathi, Mongolian, Māori, Nepali, Norwegian, Norwegian Nynorsk, Occitan, Pashto, Persian, Polish, Portuguese, Punjabi, Romanian, Russian, Sanskrit, Serbian, Shona, Sindhi, Sinhala, Slovak, Slovenian, Somali, Spanish, Swahili, Swedish, Tagalog, Tajik, Tamil, Tatar, Telugu, Thai, Tibetan, Turkish, Turkmen, Ukrainian, Urdu, Uzbek, Vietnamese, Welsh, Yiddish, Yoruba The app was made possible thanks to Whisper by OpenAI and whisper.cpp by Georgi Gerganov. ■ FAQ ‣ Can I edit the text in the app? I don't plan to support any editing. Export the transcription and edit it in a proper text editor. ‣ Why is the app so large? The app delivers the highest quality transcription on the market for 100 different languages. Rather than asking why it's so large, the real question is how is it so small. ‣ Why is the transcription so slow? The app favors accuracy over speed. However, performance is expected to improve in the coming months. ‣ Why must I keep the iOS app open while it transcribes? iOS apps are fundamentally restricted from operating in the background for extended periods. ‣ Can I delete some of the languages to save space? This is unfortunately not possible. The model has all the languages stored together in a way that makes it impossible to remove just some languages. More FAQs on the website. ■ Technical details The app uses the Whisper medium or small model on iOS depending on available memory and the large v3 model on macOS. ■ Privacy The transcription is done locally on your device. Nothing leaves your device. ■ Support You can contact me through the feedback button in the app.

Your to-do list app is probably part of the problem. Fifty flat tasks, no structure, and the one thing that actually matters buried under errands. Tatask fixes that. Break any project down into subtasks, then subtasks of subtasks — nested as deep as you need, like folders on your computer. Shrink a task small enough and procrastination stops being an option. Planning your day shouldn't take longer than doing the work. Swipe to star any task, from anywhere in your tree, and it lands on today's list. Everything else disappears — out of sight, out of mind — so your brain gets to focus on one thing at a time. A few more things Tatask does well: Visual progress rings on every task. Watching the ring fill in is weirdly motivating. Schedule time-sensitive tasks once and forget them — they surface on your Due screen exactly when they're due. Real-time sync between iOS and web. Go offline, keep working, and it catches up the second you're back online. People who've switched: "Loving using Tatask to centralise my many to-do lists and thoughts. Easy to use, simple but powerful. Would highly recommend for anyone wanting to supercharge their productivity!" — Jack F., Manager "I just love the flexibility of Tatask. I use it to track development of my startups, mostly, but also building marketing sites, and really anything." — Stuart B., Founder "Ditching Trello for Tatask has paid off enormously. Gone are the endless scattered boards and now I have a natural structure for everything I'm working on. It's as simple as Trello but 10x more useful. Highly recommend!" — Alex C., Investment Associate About Pro plan billing: If you upgrade to a paid plan, payment will be charged to your iTunes account, and your account will be charged for renewal within 24 hours before the end of the current period. You can choose to be billed monthly or yearly. You can turn off auto-renew in your Apple ID Account Settings any time after purchase.

Verdict

The call

The clearest difference is price: Tatask at Free against Aiko's $24.00. Tatask also leads on review sentiment (100% vs 86%) and update cadence (every 3 weeks vs every 6 weeks). Aiko's advantage is in-app purchases (none vs 4) and chart position (#26 vs unranked). On ads there is nothing between them.
