I've figured out a way to get Kaeru:tomo, a Miitomo revival, on a non-jailbroken iOS device. This is nice to have, as I personally think that it's dangerous to jailbreak your main device, and I didn't want to do it just to get Kaeru:tomo. Plus, I'm on the latest firmware. This tutorial will tell you how to do it.
Instructions:

1. Go to https://signulous.com/ on an iOS device. You will need to purchase a year subscription of Signulous to use it ($20/yr). Follow all steps to set it up, then install the Signulous app.
2. Go to https://twitter.com/EsignPatch and download the IPA of E-Sign. Save it to Files. (NOTE: this might be easier to do on a computer)
3. Go back to Signulous and get the UDID of your iOS device. You can also find it on the receipt that Signulous emails you. Copy it to your Clipboard.
4. Go to https://www.udidregistrations.com/check-order and paste the UDID. Download the .p12 certificate and .mobileprovision file under Certificate & Provisioning Files. Save each of them to your Files.
5. Download the Kaeru:tomo .deb patch file from https://cdn.discordapp.com/attachme...313532857573506/world.kaeru.kaerutomo_0.4.deb. Save it to your Files.
6. Go into Signulous and use the option to upload a custom IPA. Select E-Sign. Install the signed app.
7. Launch E-Sign. In the File tab, press the 3 dots and select Import. Select the .p12 file. Do the same for the .mobileprovision file, Miitomo .ipa (Select Import when asked if you want to import app library) and the .deb.
8. Tap the .p12 file and select Import Certificate Management. Enter 123456 as the password.
9. Go to the Apps tab, then select Miitomo. Select Signature, then More Settings, then Add library. Select the .deb file. Press Signature.
10. When it's signed, select Exit. On the top of the screen, select Signed. Tap Miitomo then select Share. Save the app to Files.
11. Go into Signulous and use the option to upload a custom IPA. Select Miitomo. Install the signed app.
12. If you followed all the steps correctly, Kaeru:tomo should be installed on your device. Follow the steps to set up the app. Enjoy!

@Larsenv can you dump the .ipa file you used?

It's on Archive.org. Can't link it here.

@Larsenv can you dump the .ipa file you used?

Linking IPA files including other form of warez is against the rules FYI.
