A remarkably well-designed app with a dedicated and responsive designer. **Developer response:** Thank you so much for the kind review! 🤓 ### 1/5 — New subscription! *2025-04-20* I’m really disappointed after purchasing a full access to this app , it’s updated to yearly subscription, it’s unfair! **Developer response:** Your data is not locked behind a subscription, so you can export all your data to use in another app of your choosing at any time. I’ve made sure of that. I’m sorry you feel the modest fee is not worth paying, especially as a medical professional. The single licence fee was unsustainable for me so it was either this or I remove Somnus from the App Store entirely. Details and explanation are in the FAQ on the website. Kind regards, Paul ### 5/5 — Glitch in the new Update *2025-04-16* Somnus has been working wonderfully so far until the recent updates. Having trouble with logging patients, disappearing screens and needing to get out of the app time to time for checking jew patient entry. I hope this can be fixed as soon as possible. This is an amazing app, really useful. Want the glitch gone please. **Developer response:** Thanks for the review and feedback. I have run into a few little glitches that some users on iPhone are also experiencing and it IS annoying, I agree. I'm doing my best to rectify this and v10.0.7 should address them. I've been working on this non-stop for the past few weeks. Thanks for your patience. ### 1/5 — New update broke app *2025-04-01* It was great until the latest update. It removed my paid access and no longer can use “restore purchase” option as it’s broken. No response from devs yet. **Developer response:** I’m sorry you’re having issues and I’d like to help sort it out for you but I can’t as you have either not contacted me or not read my reply. I reply to every email I receive within 24 hours. Not sure how I can reply to ‘nothing’. If you recently purchased (ie since late 2024) Somnus before I made it FREE for two months before moving to the subscription model, please let me know and see the website for details. I also note that you’re not actually on the latest update (which is currently 10.0.3). ### 1/5 — Purchased One-Time Payment *2025-03-31* Another app NOT grandfathering original app purchasers. I will not be recommending this app anymore. This developer should have recognized that the original purchasers are the ones that put money in his pocket. Smh. **Developer response:** I hear your frustration, and I genuinely appreciate that you were an early supporter of Somnus. I make almost no worthy income from this venture. When I first released the app over six years ago, it was a one-time purchase, and many users paid just $30 (many much less less) for unlimited access, updates, and support. Since then, I’ve added countless features, maintained the app, answered every support request personally, and continued improving it in my spare time - all while working full-time as an Anaesthetist. At some point, to keep the app sustainable, I had to move to a subscription model. I didn’t make that decision lightly. Subscription will hopefully allow me to keep supporting and evolving Somnus well into the future without feeling like it's a burden. Even now, users can still fully access and export their data without subscribing—the subscription only applies to adding new data. For those who bought the app just before the change, I’ve even offered a free year of subscription. I understand this model may not suit everyone, but I hope people can see the value that’s gone into the app over the years, and the need to support it moving forward. Thank you again for using Somnus, and for your support in the early days. ### 5/5 — Fantastic App *2023-12-16* Somnus has changed the way I record my cases. Intuitive, user-friendly, easy to keep track of what I’ve done, helps me if I have to review a list to give a trainee my feedback and helps with billing! A no-brainer for every Australian anaesthetist, from trainees to FANZCAs! **Developer response:** Thank you very much for the great review - I really appreciate it! If you have any suggestions for improvement, please get in touch. Cheers, Paul. ### 4/5 — Need to enter diagnosis *2023-10-22* A really good UI, convinient Need to enter diagnosis or atleast to write indication for surgery. Kindly try to update that in the app. Thank you and great work **Developer response:** Thank you for the review. You can certainly do this with a Patient Personal List of your choosing. You could have a list called ‘Indications’ and then create items in this list. They will then appear on exported reports, including Case Reports (PDF). Cheers, Paul ### 5/5 — Finally something that works! *2023-05-24* After years of fruitless searching, someone has finally developed a worthwhile app for tracking anesthesia cases. The setup is simple and the use is intuitive. Export a slick case report for credentialing? No problem! This app has saved me hours of formulating the data for tracking case averages. I give it my highest recommendation! **Developer response:** Thank you so much for the wonderful review, I really appreciate it. Let me know if I can do anything to improve things 🤓 Kind regards, Paul ### 5/5 — Absolutely the best app for case logs! *2023-05-22* I’ve been using your app for the past 5 years now and highly recommend it to my Nurse Anesthetist colleagues. To only question I have is downloading case logs from a selected time period. Can you tell me how I can download just the last year of case logs instead of the past 5 years of case? **Developer response:** Hi Robert! Thank you very much for the lovely review, I really appreciate it! The easiest way to download a specific day, week, month or year of cases is to select that range on the Dashboard, then either view the Cases by tapping on that line in the section below the Case Cards OR simply tap the export/share button. It will export all those cases for you in one file. You can also create a Search on the All Data screen to specify a precise date range, as well as add other search terms to filter your cases. Get in touch by email if you need further help and I’ll reply as soon as I can. Kind regards, Paul. ### 5/5 — Error *2023-05-06, version 8.7.1* Sorry for the question, took me a while to find the conversion tab. Therefore I´ve upgraded the stars to 5 of them.
