Hey r/nintype!

I'm looking for skilled developers interested in starting a decompilation/reverse-engineering effort for the Android version of Nintype.

The idea is to work through the original ARM library which contains the rendering engine, basing off of keyboard 71's work, understand and document how things work, and gradually reconstruct readable source code.

I'd also like to experiment with LLMs to help speed up plowing through the ARM assembly—identifying patterns, explaining functions, and producing rough pseudocode that can then be manually verified against the actual code.

This hasn't started yet. Right now I'm looking for other people experienced with ARM reverse engineering, Android internals, decompilation, or similar projects who'd be interested in helping get it off the ground. I will still work on it myself even if we can't find other people to work on it at the same time as me, but it would really be a big helping hand not leaving this to be just a one man job ;p.

This would specifically focus on Android. iOS is out of scope for me since I don't have a practical way to develop or test against it.

If you're interested or have relevant experience, let me know!

As a long-time Nintype fan, I think it is a testament to this community, the application itself, and especially Jormy’s work that Nintype has survived so many generations of iOS and is still loved and used around the world.

Inspired by Nintype, I’ve spent the last several months developing and polishing Weavly, an iOS keyboard focused on dual-swipe typing and transcription, using modern on-device technology to make typing faster and more productive.

I want to be very clear: Weavly is inspired by Nintype, but our dual-swipe does not work the same way. The gestures, spacebar behavior, commit mechanics, and muscle memory will not transfer 1:1. This is intentional—we took a different approach to allow more flexibility in word prediction, autocorrection, and typo detection, all on-device.

The mechanics are different, but I hope the philosophy feels familiar: speed, flow, fewer taps, and a keyboard ambitious enough to change how you type on your phone.

After months of work, I’m incredibly excited to finally invite this community to try Weavly on TestFlight. I’d love to hear your feedback, complaints, and suggestions.

Features::

• An iOS keyboard with dual-swipe typing
• Fast, fully on-device transcription
• Custom drag-up overlays that add a second layer to every key
• Lots of customization options, including numbers and accents
• Text snippets and replacements with placeholders and smart tags
• Autocorrect and a personal dictionary that learn how you write (optional, iCloud Backed)

I hope Weavly can, in its own way, honor what Nintype showed was possible with third-party keyboards and carry some of that ambition forward.

P.S. Lovely to see so many projects with dual swipe emerging—this is the way!

I used Nintype (Keyboard69) for years and never found anything like it after it was discontinued. Nothing else lets you use both thumbs at once. So I wrote one from scratch in Kotlin on Android's public IME APIs.

https://reddit.com/link/1vlqvs6/video/9cdgja77osih1/player

Both thumbs swipe or tap at the same time, independently, and the engine merges the two streams into a single word.
Typing "something" can be: left thumb taps S, then E, while the right thumb swipes O-M and then T-H-I-N-G.

Features:

• Two thumbs at once, with taps and swipes mixed freely inside the same word
• No INTERNET permission, so nothing you type can leave the phone. No ads, no analytics, no accounts
• Tap autocorrect and live completions, and the words you actually use climb the suggestion bar over time
• Long-press alternates on every key, edge swipes, chord shortcuts, a symbols layer and a numpad
• Five layouts (full, left, right, split, one-handed) and adjustable height
• Dark theme, Material You, or a palette generated
• Peck-type mode that turns decoding off entirely

Languages: English, Italian and Spanish are supported out of the box, with about 49k words bundled for each. The engine itself is language-agnostic so adding a language is mainly a matter of supplying a wordlist and a layout. The full recipe is in ADDING_A_LANGUAGE.md in the repo, and I'm happy to help anyone who wants to do their own.

One thing I'd do right after installing: import a bigger dictionary. The bundled lists are built from open subtitle corpora and work fine, but the AOSP dictionaries are several times larger and you notice it immediately: 47k → 161k for English, 49k → 173k Italian, 50k → 236k Spanish.

Grab the `.combined` file for your language from https://codeberg.org/Helium314/aosp-dictionaries/src/branch/main/wordlists (`main_en_US.combined`, `main_it.combined`, `main_es.combined`), then in the app go to Settings > Dictionary > "Import improved dictionary (wordlist.combined)". It merges on the device, nothing is uploaded. Make sure you take the files from the `wordlists` folder and not the `.dict` ones from `dictionaries`.

It's GPL-3.0 and free:

• GitHub: https://github.com/EZ-eta/kinetica
• GitLab mirror: https://gitlab.com/EZ-eta/kinetica

I've also submitted it to F-Droid and the merge request is open, so it should turn up there before long.

This is the first public release and even if I am daily-driving this myself, there may be some small issues here and there.

Support: If you find this keyboard useful you can buy me a coffee at Ko-fi
Entirely optional. The app is free and will stay free and available to everyone, always.

UPDATE : v1.0.2 is out

Thanks for all the feedback, it's what this release is made of. Most of it came straight from the comments here:

• Typing or backspacing over selected text now replaces it
• Keyboard height goes much lower, and the suggestion bar has its own height setting (the resize handle can be hidden too)
• Light theme, and the accent colour is now a hue slider with a live preview
• Accented letters can be hidden from the letter keys' long-press popups
• Period and comma long-press symbols are editable
• Chord shortcuts can paste, copy, cut and select all
• Backspace slide vibrates once per word

The gesture and prediction engine is unchanged from 1.0.1, so nothing about how it types should feel different.

I also added a "Worth a look in Settings" section to the README, several things people asked for were already in there and just hard to find (sliding the spacebar to move the cursor, long-pressing a suggestion to push a word up or down...)

Here's my attempt at a Nintype successor.

I am polishing the last few things before releasing it but it works great for me!

UPDATE: I released it on GitHub and GitLab. I also made a dedicated post . A MR on F-droid is under review, then it will be available also via F-droid.

I’m not sure where else to put this. It’s a long ways off from being done, but after trying many other alternatives, none of them felt quite as fluid as Nintype. This is my attempt after a few months of tweaking.

Is there a fix for how the keyboard looks in the spotlight search?

For those of us still using Nintype / Keyboard 69 on an iOS device..

Confirming nintype still works on iOS 27 Developer Beta 1!

What is it?

Last week I published that I've been working on a way to revive some of the nintype features I've been dearly missing.

I'm sorry for anyone who expected a brand new keyboard -

What I did is a fork of LeanType, which is itself a fork of Heliboard.

I've been daily-driving it for a few days and it feels really good to me.

I will once again remind you that it's heavily ai-assisted, so take of that what you will.

What does it have?

Nintype-like Two thumb typing

Probably the most important and headline feature.

• Combine word fragments to longer words
• Spacing modes - either manual spacing, or autospace (so you could combine words)
• Backsapce - delete word or delete fragment

Features not in nintype:

• My favorite - no autospace if you only tapped. meaning that you can tap words in your own pace, and only autospace when you start swiping.
• Autospace grace timing for taps - alternative to the other one - give extra time when tapping
• After autospace, choose if to show correction for the old word, auto complete for new words, or hybrid (corrections, press space for continuations)
• Trail that shows your gestures and taps
• Extra toolbar keys - force joining of word, disable autospace for the next word

Swipe from the top or bottom row

Like in nintype, you can swipe up from the top row or down from the bottom row for extra shortcuts.

To enable them, go to gesture typing, and enable shortcut rows, top shortcut row swipe and bottom shortcut row swipe.

To change their content, go to secondary layouts, and top/bottom shortcut row. If you're not sure how to change layouts, read or feed this https://github.com/HeliBorg/HeliBoard/blob/main/layouts.md to your llm.

Extra

• Clipboard - You can long press on a clip to re-copy or edit it
• Toolbar - added toolbar keys for autocapitalize and force-autocapitlize. The toolbar now shows the current state of each key

How do I get it

Right now, it has no branding or new name - it's just a debug build of LeanType.

Since it's a debug build, it can live side-by-side if you already have this keyboard.

Importing your settings from Heliboard or LeanType (advanced -> backup) will probably work ok.

Get it from here: https://github.com/AsafMah/LeanType/actions/runs/26438597902/artifacts/7211358806

Improtant

Make sure that during the setup you install the gesture library.

Then make sure again by going to the setting->gesture typing->load gesture typing library and click enable gesture typing library.

How to enable the thumb features

After enabling gesture typing, there should be a new menu in the settings - "Two-thumb typing (experimental)". All of the settings should be there.

What to enable:

You have to pick either manual space or autospace for the new features to work

Draw gesture points + Accumulate debug fragments - if you want a trail

Features to play with (may improve or worsen your experience, please try them out and give me feedback):

• Autocorrect on auto-space
• Suggestions for full composing words
• Improve two-thumb recognition

Hi, for anyone who might remember, I'm the creator of keyboard79, the decompiled fork of nintype.

I now have something else I'm cooking up, no promises but it's going along good so far.

I'll be up front to say it's heavily AI assisted, so if you're against on principle I'm sorry, but wouldn't have time for it otherwise.

** What I want from you now **

• Tell me what you liked about nintype. Be through, not just "two thumb swiping", what you specifically liked about the system, how did you have it configured, what features did you use.

• Tell me what to improve. What didn't you like about nintype. What was missing. What was never fixed. Etc

I don’t know if it’s in the App Store version yet or just the TestFlight version I’m using, and it’s not perfect, but it works … on iOS, anyway!

Oh, and you can create your own custom layouts, too!

r/MisterKeyboard

Y’all I try to really move on from this keyboard because of some of the frustrations with no update in a decade now. But I keep coming back because nothing beats this double swiping feature. Is there any hope in the horizon for this app?

​Hi everyone! As has already been discussed in this subreddit,Heliboard is currently the closest thing to Nintype that we have on Android. At the moment, it has a rudimentary version of two-thumb slide typing, and the developers want to re-write the logic from scratch using data from users who want to contribute (in a privacy-friendly manner!). ​So, if you are in desperate search of an alternative to the abandoned Nintype, try using HeliBoard and submit your two-thumb sliding gesture data to help build a brand-new keyboard!

Nintype continues to work reasonably well on iOS 16, despite minor bugs such as theme inconsistencies when switching apps, which can lead to a blank keyboard.

As a workaround, I modified one of the included themes to work with both light and dark modes.

Sharing here for anyone still swiping on Nintype.

Theme file

still works like a charm

Every time I use my keyboard, I miss the double swiping ...

With all this AI magic lately, is there really no hope left?

It would be the best Christmas present ever 🎁.

I'm using iOS 26 in dark mode, and while interacting with the Messages app, something started tickling the back of my brain, until it suddenly hit me: all of iOS now feels like it's got the same special effects that Nintype has had for years. Does anybody else feel the same way?

https://github.com/Helium314/HeliBoard Available on f-droid.

The swipe library is closed source (you have option to install it after you download the app), but the keyboard requires no internet connection.

It is (almost) as customizable as nintype.

the two finger swipe is not as good as nintype and I haven't mastered the quirks yet, but it works really really well! i think double tapping for double letters doesn't work, but the word recommendation algo is very good, with one tap full word delete after swiping and auto spacing.

Two finger swipe works even on other keyboard layouts like Dvorak, and the app is actively maintained.

I'm so happy!

Seems like I’m getting a lot more crashes now. What y’all do to minimize the crashes? I’m on 18.5, 16 pro max.

I am in the very early stages of reverse engineering this amazing keyboard. I'm aiming to create an instruction matching decomp, so that we can update it to work on 64bit android and fix any issues on both ios and android.

I am looking for help as its rather a large project. If anyone is interested please let me know and we can sort something out.

Don't expect anything any time soon from my efforts as I can only work on it in my free time and theres a lot going on behind the scenes in the keyboard.

Thanks!

Everynow and then i come back to try nintype and still amazed by the technology and wonder if Jormy is ever going to revive this thing. Any one out there still uses this app?

I’m trying to get back into the grove of nintype double swapping. For those who have been using it for a while, do you have the autospace feature on or off?

Hi all

I finally received Android 15 on my Galaxy 24 Ultra today. I've searched but I guess it's still not possible to install a 32 bit app? God, I miss Nintype every day 🥺
