The Ministry of Defence has integrated the LifesaverSIM tactical medicine simulator into the Army+ app. What it offers

The official mobile app for Ukrainian service members, Army+, has added the LifesaverSIM simulator, which turns complex medical protocols into a structured training-game format. The simulator is being developed by a Lviv-based team led by entrepreneur Olesia Dyachyshyn. Defender Media spoke with her about cooperation with the Ministry of Defence, the current tactical medicine courses available in the app, and the team’s future plans.

What this is about

On 4 February, the Ministry of Defence of Ukraine announced the integration of the LifesaverSIM mobile tactical medicine simulator into the Army+ app.

Army+ is the official mobile app for Ukrainian Armed Forces personnel, created by the Ministry of Defence to digitalise services. The app includes the Plus programme, which offers partner services and bonuses for service members — transport, delivery, shopping and more. The programme now features a new Learning section, where LifesaverSIM has become the first integrated educational product.

LifesaverSIM is a Lviv-based startup developing a mobile tactical medicine simulator. Training takes place through realistic mission scenarios on a smartphone or tablet and helps users practise providing aid to wounded soldiers in combat conditions. The app has 130,000 registered users, and its audience has grown by 50% over the past year. In December 2025, the Techosystem association included LifesaverSIM in the Top 100 Rising Ukrainian Startups 2026.

How LifesaverSIM entered Army+

Olesia Dyachyshyn says the startup team itself proposed integrating the simulator into Army+, and the Ministry of Defence supported the idea. Work on the integration began in autumn 2025, with the most intensive phase taking place in late January and early February.

Dyachyshyn explains that from the very beginning, one of the key challenges for the team was user verification — ensuring that LifesaverSIM training courses were taken specifically by Ukrainian service members. “Access to the basic course was provided through Diia, like for all Ukrainian citizens,” she says. “For the advanced course, we created an internal secure method that works but isn’t particularly convenient or simple for either the military or us.” This is why the team sought integration with Army+ from the moment plans for the official Ministry of Defence app became public.

LifesaverSIM is free for Ukrainian users. The integration with Army+ is also not monetised, the startup’s co-founder told Defender Media. “This integration is a way to provide our military with knowledge free of charge, conveniently and securely,” she emphasised.

What LifesaverSIM includes and how to access the courses

To access the simulator, a service member needs to download LifesaverSIM from the App Store or Google Play and log in via Army+. No personal data needs to be entered — the profile is created anonymously. Users then gain access to the courses “For All Service Members (ASM)” and “Combat Lifesaver (CLS)” with no time limits or restrictions on the number of attempts. Training also works offline after the materials are downloaded.

Diachyshyn says ASM and CLS are the core tactical medicine courses. “Currently, advanced Ukrainian units train fighters at the CLS level,” she adds. “The basic ASM level is not enough. This requirement is dictated by the war.”

According to her, the startup team has many plans for further development of the app. These include a Combat Medic Course (CMC), a specialised course for military surgeons, expanded functionality for instructors, and the integration of artificial intelligence.
