Super-effective Practice Tool

Modacity has truly helped me change practice routine in all the best ways! The ability to organize playlists and practice items allows me to leverage my practice time. The improvements and mastery features then further help me figure out what really needs my attention.
My biggest success with Modacity was in March/February 2018. I was preparing to go on tour with a bluegrass group playing bass and singing harmony (with a little lead thrown in there), and I had 20+ songs to memorize. It was a truly daunting challenge, and I procrastinated. About 2 weeks from the departure date, I finally decided that it was time to learn these tunes. Using the playlist feature, it helped me see all of what I needed to do, and the mastery feature let me see what needed work. With about 1.5-2 hours of practice a day and some interleaving strategies, I solidly memorized those songs. I didn’t even have to worry about memory lapse on the tour! Using Modacity as a tool for effectiveness let me just have fun. Hope it helps others keep pickin’ and grinnin’!

The Practice App Every Musician Needs

I very rarely write reviews. But this app is one of the best I’ve ever had.

No matter if you’re a beginner or a professional performer, this app will drastically change your practice habits.

Before this app, my practice was disorganized and sporadic at best. Sometimes I’d keep track in a journal. Other times I’d lose my pencil and shrug off even touching the piano.

I’m now practicing (actively working on content) around 1-2 hours per day because Modacity has made it so easy to track and log songs, practice sessions, etc.

The price might be a bit high for subscription, but there’s not an app out there that can compete with Modacity right now. The free version has plenty to get by with, but I love being able to track exactly where my hours are going and how I’ve improved.

Looking forward to more features soon! (I would personally like the Italian tempos in the metronome app... tiny addition).

Hoping to see a theory/music knowledge part added in the feature, but that’s not really why I’d continue to use the app anyway.

Enough with the prompts and timers!

All I’m trying to do is set up my first practice routine and I keep getting bombarded by pop-ups to rate the app and the practice timer keeps starting. First, if you want a fair rating, don’t try to make me rate the app within the first minute of using it. I assure you, the rating will be poor. If I could just choose not to rate it and be reminded the next time I opened the app, that would be reasonable; but the rating prompt comes up every time I open an item or edit something. So fine, have it your way—2 stars for being incredibly annoying. Also, enough with the auto-start timers. At least one of them seems pausible by tapping on it, but the one that sits in the bottom left starts as soon as I open the ‘page’ and doesn’t stop unless I tap Finish. What did I just finish? I hadn’t even started anything yet. I’ll be a practicing fiend before I even pick up my instrument at this rate. I can’t really comment yet on other features—awesome or awful—since I want to hurry and rate this app just to get rid of the stupid prompt.

Developer Response ,

I'm sorry, but it appears you misunderstood our star rating system. That is not asking you to rate the app, it's asking you to rate your mastery.

In general it takes between 1 and 3 taps on the phone to start practicing with Modacity. We're always working to improve our interface and if you have any constructive feedback to share, we'd be happy to incorporate it, since we are constantly updating the app (in fact, "Don't auto start timers" is a new setting we added since this review).

Feel free to email hello@modacity.co and we will offer you personal support getting set up in the app, as well as fully understand and learn from your negative experience, in terms of how we can adjust the interface.
