Unfortunately, there is no version for the iPhone or iPad. iOS is on our to-do list, but with very low priority as it is so much more work and we are focusing on Android to make one of the best apps there.

Yes, you can run smartChord on Windows, Linux, Mac and Chromebook.

Yes, you can use smartChord on a Fire phone. Since you purchased smartChord through Google, you’ll need to install Google Play on your Fire phone. Only Google has access to your purchase information.

smartChord and install it.

A purchased version of smartChord can be easily reinstalled or used on multiple devices. You don't have to pay twice. Just install it on your devices. It is important to use the same Google Play account with which you have bought smartChord. If it was an in-app payment, that's enough. If it was a separate s.mart app, just install it on your device. You can find your bought apps in the order history: https://play.google.com/store/account/orderhistory

You can check if everything is installed correctly:
'Info' -> 'Your products'.
Your purchased products are listed there.

Open the Table of Contents. Switch to the ‘multi select’ mode. Click the ‘Select all’ menu item. A toast shows the number of selected items.

Unfortunately, it's not possible to run all smartChord features without the Google services which are part of Google Play. Some feature depend on them. Also the payment and accounting is completely in Googles hand.

smartChord allows individualized tone names and symbols. You can define your personal preferences in the general settings. These settings affect all of the smartChord features.

The chord diagrams shows the notes according the settings. But you can change the setting "Diagram info" to 'Theory' so the notes are displayed according the musical theory.

The songbook shows the chord names according your 'Name settings' in ‘Tone names’ and ‘Symbol’ settings. The intention is go see always the same chord names independent to the source of your song texts. So you'll always get a C#, even if the original chord of the song is written as Db. But there is a songbook option to force the songbook to show the original chords. But keep in mind, that with this option activated, the transposing is deactivated!

We chose SO instead of the more common SOL because there is limited space to display note names on small displays. But SO is also a valid naming/abbreviation.

Moving to a new device is quite easy and done with a few steps.

When you configure a new device, it's important to use the same Google
Play Store account with which you have bought smartChord. Then you can
install smartChord on your new device. If you have bought a s.mart app,
you have to install it too. You can find your bought apps in the order
history: https://play.google.com/store/account/orderhistory

Normally the producer of your new device provides a tool to move the
data from the old device to the new device (e.g. ‘Smart switch’ from
Samsung). Also Google can do the job with the backup and restore feature.

But also smartChord has also different possibilities to move or
synchronize data.

The best way is to copy a backup file to the new device like described in our documentation:
https://smartchord.de/docs/general/backup-restore/

If this is not possible, you can use the synchronization feature:

We want to make smartChord the best and most popular music app worldwide. To achieve this great goal, we have to go new ways. We follow the concept of a huge toolbox where the tools are very well integrated into each other. We made smartChord the central app with all the functionality and all the data.

As not every user needs every functionality, we made smaller packages for various purposes. The packages are represented by our plugins - the s.mart apps like the s.mart Mandolin. The s.mart apps just unlock functionality - but they need smartChord.

Your benefits:
⭐ smartChord as the central app, contains every functionality and data
⭐ The UNLIMITED provides includes also future features and apps automatically. You'll never get asked to buy a new app or feature.
⭐ smartChord and thus every s.mart app is improved at least two times a month
⭐ The tools complement each other or build on each other
⭐ Uniform concept and user interface
⭐ Share the data between the tools
⭐ No need to update multiple apps
⭐ Very small memory footprint on your device
⭐ Early access to new features
⭐ Quick bug-fixes

- The 'wake lock' permission is needed to prevent sleep mode while the metronome is playing
- The 'external storage' permission is essential to import or export stored items like songs
- The 'network access' permission is needed for the internet search for songs (and maybe ads in the future)

The sound of the instrument is produced by your phone. Some phones have really bad sound. And no phone has really authentic sound, because it is produced by the phones MIDI producer.

There are color schemes which will help you to distinguish the notes of different degrees in chords, arpeggios, scales and the circle of fifths at a glance. You can switch the color scheme in the settings of the 'Home' screen.
