What's New in Somnus

11.3

October 16, 2026

NEW • iPhone Duo Support - Folded, iPhone Duo works like your iPhone - Unfolded Somnus switches to the iPad layout • Timers Summary Tile on the All Data screen (and optionally the Dashboard) - Includes a dedicated Timers list. - Every timer is grouped by name with its shortest, longest, median and mean duration, and tapping one shows its Cases. - Create new timers to drag straight onto Cases and Templates - Change a timer's colour or icon across all its Cases in one go, delete a timer everywhere, and export the statistics as CSV. • Smarter Patient Matching - Somnus looks for an existing Patient as soon as a label is scanned or a name, date of birth, hospital identifier or Medicare number is entered, not just when you tap Save. - A complete Medicare number now finds Patients on its own, in whatever format it was stored, and family members on the same card are offered as possible matches. - If a match turns up after you have already added Comorbidities, Personal List items or biometrics, choose Merge to keep them and fill in the rest from the saved Patient. • Single Selection Option for Personal Lists - Some lists only ever have one option per case. Mark any Personal List as Single Selection from its context menu and picking an item swaps out the previous one - As an example, a Patient can never end up with two Health Funds. - The rule applies to pickers, drag & drop, label analysis and AI suggestions, - The built-in Health Funds list is Single Selection by default. • ASA Saved with Patient - Previously this used to simply show their ASA on their last case but if they had no cases, and any comorbidities, they'd only appear as ASA 2. - Each Patient now carries their current ASA level. Set it when creating or editing a Patient, see it in Patient lists and charts, and it pre-fills their next Case. - Saving a Case still keeps it up to date, and existing Patients are filled in automatically from their most recent Case. • New File > Import Theatre List menu command on Mac and iPad (Pro). • MBS RVG 1 August 2026 MBS RVG • Choosing an existing Patient from Potential Matches no longer discards details you had just entered or scanned (see above) • Editing a Patient with a single Case now updates that Case's weight, height and BMI correctly. • A Patient with no Comorbidities always shows as ASA 1, and attaching a Patient to a Case no longer leaves the previous Patient's ASA behind. • Fixed rare crashes from database access on the wrong thread during saving, clean-up and first-run setup. • Export, backup, import, restore and Merge Duplicates all understand the new Patient ASA and Single Selection fields.

User reviews

Ideal

If only all medical tech and software was designed with this level of convenience and user-first common sense. A remarkably well-designed app with a dedicated and responsive designer.

Response from developer

Thank you so much for the kind review! 🤓

New subscription!

I’m really disappointed after purchasing a full access to this app , it’s updated to yearly subscription, it’s unfair!

Response from developer

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

Glitch in the new Update

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.

Response from developer

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.

New update broke app

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.

Response from developer

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).

Purchased One-Time Payment

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.

Response from developer

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.
