AK-17 apps

My Android development started in 2017 under the ‘AK-17 apps’ (commonly referred to as just AK-17 or AK17). It is an independent Hungarian mobile app development team and we specialize in native Android apps, like Chronology, TimeNotes and TimeNotes Lite, Rally Raid. Find them on Google Play.

Rally Raid

Rally Raid was the first released app by AK-17 apps. The goal of this app was to represent the events and excitement of the cross-country rallies like in Dakar Rally, Africa Race etc. The events of the app are based on real incidents, which means all of them happen during the real stages. You need to take into account every factor of the condition. Every decision you make in an incident it affects the probability and severity of the upcoming incidents.


Chronology and TimeNotes are trivia apps based on historic events. The main difference between them is that Chronology focuses mostly on commonly known events. These are probably learnt by everyone who already passed the elementary school. Or has some experience in life about the events, which happened in world history.

TimeNotes (TimeNotes Free)

The TimeNotes handles many more events divided into several difficulty level and much higher knowledge level is required to have a successful session. The number of events in case of Chronology is about 500, this value in TimeNotes is more than 22 thousand.
