But after a period of paid use, it suddenly stopped working. I contacted the developer and never got a reply. I’m disappointed, especially after being a loyal user. Please fix this or offer a refund. ### 4/5 — License problems *2025-07-26* This was one of my favorite tools for memorizing the fretboard and visualizing intervals. I purchased the full version, however it defaults to the limited version if it can’t contact their server on the internet. Lately it can’t find their server so it no longer works. ### 5/5 — Unique App, well done *2025-07-16* Very comprehensive and effective. Stands above the rest. ### 4/5 — Great app, but… *2023-11-02* This app is a great way to work on improving your knowledge of the notes, intervals and scales, is helping me a lot. I would give it 5 stars but it doesn’t have a landscape orientation view on the ipad, which is disappointing in 2023. ### 2/5 — Stop asking me about ads after I have paid *2022-12-21* Fix this …. Every time i use your app there is a pop up informing me of relevant ads. I shouldnt see any ads, or any pop up message regarding any ads after I have already paid for this. ### 3/5 — Needs better iPad support *2021-04-26* Needs landscape view ## Frequently asked questions about Guitar Intervals Unleashed ### What is the NANDI Method in Guitar Intervals Unleashed?
