4 years later and there are still a reasonable number of people finding these Lessons useful.

To further streamline the process, selecting any Sub-Topic will launch it in the new 'Lesson Player' Tab.

From there, a new menu will allow much easier movement between Topics and Sub-Topics.

Alternatively, just go straight to the 'Lesson Player' Tab.

Gratified to see that there are a reasonable number of people still finding these Lessons useful.

So I've decided to try and streamline the process to make it easier to, in particular, navigate between the lessons. This was originally controlled by the code within the App.

Spotted and sorted a problem with some of the Worked Examples not loading images.

Whilst I'm not definitely giving up on this App, time & technology have moved on and I'm not sure I can spare the time and effort to finish this App.

However, over the last few years, I've been able to use the Lessons on my whiteboard but hidden behind a Tab that was labelled "Extras". You are free to use them. Tab is now more clearly labelled as "Lessons".

I'm presently writing Topic 5 - Calculations and Topic 6 - Acids and Bases (working titles, may change).

At that point I'll be rebranding the App as N5ChemTutor1 and will start charging a modest fee for the App. If I achieve sufficient sales, then I will be able to start on N5ChemTutor2.

N5ChemTutor App (1.4.1) is now available on App store. This inludes various improvements and Topic 4 - Structure and Bonding.

N5ChemTutor App (1.3.1) is now available on App store. This inludes various improvements and Topic 3 - Formula and Equation Writing.

I've also made the decision to revert to a totally Free App for the foreseeable future - mainly to support schools that install Apps on Devices they supply to their pupils.

N5ChemTutor App (1.2.1) was uploaded App store. This inludes various improvements and Topic 2 - Atomic Structure and Nuclear Chemistry.

This is the first of the 2 or 3 Topics that I will charge for.
