It’s easier to use, fun to play, and my students enjoy practicing with it. Excited to see what comes next! ### 5/5 — So much better! *2026-07-08* This upgrade was much needed! My beginner students can easily press the buttons now instead of struggling with turning the wheel. The graphics look much better, and I love the interactive learn page for showing the relationship between all the intervals, and lines and spaces on the staff. Well worth the money. **Developer response:** Thank you so much! I'm so glad to hear you've been enjoying Interval Jump with your students. It was designed to make learning intervals feel more like a game than flash cards, so it's wonderful to hear that's been your experience. Thanks again for the kind words and for sharing it with your students! ### 5/5 — Cute game for beginners *2026-07-08* Great for music students starting out! ### 5/5 — Amazing resource for lessons! *2026-07-08* I just found this app and already am obsessed with it!! What a fun and easy way for students of all ages to practice interval recognition. I love the options for ordinal/numbers (2nd 3rd etc) as well as words (repeat, step, skip, leap). This is going to become a staple in my studio, I’m sure of it! ### 1/5 — It needs an update! *2026-04-02* So much potential but it is too difficult for little hands to select the correct number on the moving wheel. The timer gives some motivation but a destination to arrive at because you didn’t make many mistakes etc… would make it outstanding. Please, please, please update the dial to a better touch option! Something stationary? Like a column of little box options to select from unison and up to P8 for top half of column and a unison down to P8 for bottom half of column. **Developer response:** Thanks so much for the thoughtful feedback! I completely agree the wheel could be tricky, especially for younger players. In the latest update, I added a stationary button layout as an option alongside the original wheel, and it's made interval selection much easier. I also love your idea of adding a destination or goal to work toward, and that's something I'll be exploring in a future update. If you get a chance to try the new version, I'd love to hear what you think. Thanks again for helping make Interval Jump better! ### 1/5 — Too touchy for children *2025-07-02* Needs number buttons along the side that indicates up or down rather than the wheel. Or make the wheel have settings for touch sensitivity. Otherwise it would be a great game. Also needs goal for where the frog is jumping. **Developer response:** Thanks for the great suggestions! I'm happy to say the latest update adds a stationary button layout, along with a sensitivity setting for the wheel, making interval selection much easier. I also like your idea of giving the frog a destination or goal to jump toward, and that's something I'll be exploring in a future update. Thanks for helping make Interval Jump better! ### 1/5 — Terrible App *2024-11-28* There are no instructions! If this is for a beginner you would think there should be something to tell you how to use it. Total waste of time and money. Would not recommend. Does not deserve even one star. **Developer response:** I'm sorry to hear your first experience was frustrating. Based on feedback like yours, I added an interactive tutorial to help new players get started, along with a replay tutorial button on the Learn page. I hope you'll consider giving the latest version another try—I'd love to hear what you think. ### 5/5 — Love it *2024-11-22* Seriously, it’s a great way to train your music brain **Developer response:** Thank you so much! ### 5/5 — Fun and Effective App for Music Students and Teachers! *2024-10-14* As a music teacher, I’m always looking for engaging tools to help my students master their musical skills, and Interval Jump is an absolute gem! The app’s fun, game-like approach makes learning intervals exciting and accessible. This game is well-designed to suit different skill levels, and it’s perfect for both beginners and more advanced learners. Highly recommend this app to any music educator or student looking to sharpen their skills in a fun, engaging way! **Developer response:** Thank you so much for the kind words! It means a lot to hear that Interval Jump has been helpful in your teaching. I hope your students continue to enjoy it, and I really appreciate you recommending it to other music educators and learners! ### 5/5 — Fun and simple!! *2024-10-08* I am just learning to play the piano and this is such a fun and simple app to help me memorize my intervals! **Developer response:** Thank you so much!
