Very cleverly timed to your breathing and a great way to relax. I use it both during the day when I just need some calm and at the end of the day to prepare for sleep. Highly recommended! ### 5/5 — Lull *2019-07-01, version 1.0* Fantastic, so relaxing & easy to use. I love it, & my family agree. Thank you so much - definitely a 5 star rating - recommend it highly. Gwanara ### 3/5 — Cool idea, needs work *2018-01-08* Didn’t work well with my iPhone SE (timing of the music seemed off, maybe due to accelerometer?) Now with my iPhone 8 it works better, but there are glitches in the music (sounds like a CD skipping....?!) that are wayyy too distracting to ignore. Wish this app was more like BellyBio, with the log of past sessions, different music choices, etc. Such a good idea, just needs some tweaks and it would be five star for sure. **Developer response:** Thanks for your feedback. We haven't been able to notice your issues on iPhone SE nor 8 but we'll try again... We're working on a major overhaul in the coming months. Regards - BellyBio Team ### 5/5 — An improvement over bio belly *2017-10-24* I like this better than bio belly since you can chose no music as an option and has a timer. Simpler but I did not need the other options. ### 4/5 — For Females too ?? *2016-05-11* males breathing is abdimothoracic type and in females thoracoabdominal, so is it same for both, couldn't figure that out ### 5/5 — The best *2016-04-24* I'm so elated to see the developer of Bellybio is still working on this wonderful idea. I've tried several breathing apps in the App Store, some of which are very popular and even boast of being chosen the best health app of the year and being featured in this and that magazine and what not, but still Bellybio and, now, Lull are the best. I think part of the problem for them not being that popular is the marketing side of things. The developer should consult with a professional on this regard. That said, Lull is doing better on that side of things. Bellybio on the other hand ... I don't know, the icon and the overall design is kind of... raw. Not streamlined at all. And still the App itself is awesome. The idea is very simple: lay your device on your belly and follow the sound cues to engage in a wonderful deep belly breathing session. Your device will respond to your belly's movement and in its turn give you realtime feedback so you can adjust your breathing. Lull is an app clearly derived from the developer's other app, Bellybio. If I had to guess the reason for this is that the developer with Lull, wants to give us a more simple and direct relaxation tool stripping away many of the features on the other app. I hope I'm wrong and hope the developer has actually, maybe, rewritten the app's code for Lull to make it more stable and will eventually add the missing features. Because those features don't get in the way at all and I actually love the. A graph showing your breathing rhythm, a log telling you for how many minutes you did the breathing exercise, your stress level (love this one!!), how many breathes per minute you take and even your Qi production during the session (although I don't know how you could calculate this one, there's no explanation about such process, it is very interesting nonetheless and I like it too (I think there is a relationship with your breathing rhythm and what it shows). I should add that for me the breaths taken per minute info is very useful since I'm working with the Buteyko method and that's an essential factor. Now you may wonder why, after extolling the virtues of Biobelly, I just don't use that app and skip Lull all together. Well, that's because Bellybio hasn't been updated in a while and is now very buggy. Still functional, but buggy (it freezes up, it stops working after you check the log, you can't change the music-yes, that's another feature- etc.). That's why I hope Lull will eventually become the new full-featured Bellybio. If not, please developer keep working on Bellybio. Pretty please!! As of now both apps are free (Bellybio has in-app purchases for different music, which by the way don't seem to be working). So get them NOW!!! And for my part I would gladly pay for a PRO version without blinking. I just paid for another very popular breathing app and although it is a very goo app, Bellybio and Lull are way better. Real biofeedback in realtime. Just wonderful. Thank you so much developer, I really appreciate your work and love your apps. Keep up the good work I'll be looking forward to it. ## Frequently asked questions about Lull ### What is Lull used for? Lull is designed to make deep abdominal breathing more pleasant and effective.
