Tuner by Frido vs Centimental

Tune your acoustic or electric guitar, save your own lyrics and chords, and follow them as you play. Tuner by Frido combines a guitar tuner, a personal songbook, and editable song ideas in one app. GET YOUR GUITAR IN TUNE Play a string and see whether it is sharp, flat, or in tune. Clear pitch feedback helps you tune acoustic and electric guitars to standard six-string tuning. Choose each string yourself, or let Auto Move take you to the next one when it is ready. KEEP YOUR SONGS READY Write and save your own lyrics and chords in a personal songbook organized by artist. Songbook is an editor for your own material, not a catalogue of songs or ready-made song transcriptions. Keep different arrangements of the same song, add the key and tempo, and write down capo positions, strumming patterns, or anything you want to remember. FOLLOW ALONG WHILE YOU PLAY Open the lyrics and chords you have saved in Live mode and let them scroll as you play. Adjust the text size and scrolling speed, add timed pauses where you need them, and loop a song to keep practicing. FIND YOUR NEXT SONG IDEA Jam gives you original song sketches across different styles, including rock, folk, blues, funk, and jazz. Each sketch has chords and sections ready to play. Change the key, edit the chords, and rearrange the sections to make it yours or start with a blank Jam.
