Why my profile rank and score did not increase?

  • Currently, the only way to increase the rank and score is by playing the beatmap list specified in Online;Daily
  • Playing Solo is akin to playing offline, for now.
    • Even if the beatmap is 100% same as the list and gained a new record, it will not be counted towards the profile as long as playing in Solo, online or offline.

I added a new beatmap and T-Aiko! didn't load it

  • Did not hit the refresh button at the upper-right of the "Select a Song".
  • Placed the beatmap at the wrong beatmap directory or set a wrong beatmap directory. Set the beatmap directory properly and place beatmaps to a proper beatmap directory.
  • [Using T-Aiko! Online's DDL] If the download was interrupted/incomplete and cannot be extracted, there will be a pop-up to notify about it. To rectify this, use file manager to search and delete the bad beatmap file manually. Redownload it after that.

I have a lot of beatmaps at osu!droid/Songs...

  • From Main Menu, press Options -> Song Folder.
  • Modify mnt/sdcard/T-Aiko/Songs to mnt/sdcard/osu!droid/Songs.
  • Return to Main Menu.
  • Press T-Aiko application and go to Solo/Online (Song selection). Beatmaps should appear.
    • If new beatmaps did not appear, press the refresh button located at the upper-right screen. It will recompile the beatmaps library.

Can I use the old T-Aiko/osu!droid account?




  • T-Aikov2 used to be supported by advertisements until 10/11 March 2017 (2017-03-10/11) update (version 2.4.0), where all the advertisements has been removed.
    • Before that update, the only way to remove the advertisement permanently is by applying for the Senpai upgrade.
    • The advertisement usually pops up once a difficulty was completed and directed to the results screen.
    • There will always be five (5) seconds cooldown time before being allowed to return to the song selection.
    • The advertisement does not pop-up when played offline.
