Sorry for the delayed response
The concept sketches have been completed and the feature list for version 1 are as follows.. The initial version will be for iPhone/iPod Touch only, but future versions will be released on Android as well.
1. Compatibility chart for all marine fish
2. Care reference guide for all marine fish, corals, and inverts (with the ability to search and narrow your search down)
3. Integration with Google Images API. This will allow you to enter any fish, invert, or coral and it will display numerous images of each (This was done to make the app more lightweight. If we had images integrated with the app itself, it would be too large)
4. Log - It will automatically pull the current date, then provide spaces to log SG, Ammonia, Nitrite, Nitrate, Calcium, Alk, and pH.
5. Schedule - It will allow you to schedule water changes, feeding, dosing (with a space to enter what you're dosing), top-offs, water testing, order goods (with a space to enter what goods), change bulbs, and other (with a space to enter whatever you want). Once you schedule these events, they will automatically added to your calendar with pop-up reminders.
6. Parameter Graphing - You'll be able to enter a start date and end date. From there, you can choose which parameter(s) to graph (SG, Ammonia, pH, etc). Once you select your parameters and press "graph it", a line graph with corresponding dates will show the progress of your parameters in a visual manner.
7. Schedule Graphing - This will be exactly like parameter graphing, except it will be for scheduled events that you've completed. You'll be able to choose which item(s) you want graphed and there will also be a drop down for the "dosing" category since most people will have scheduled more than one type of dosing.
8. Settings - There will be some miscellaneous settings on the "other" page. We'll also offer a section for sponsors and helpful links. Trusted companies will be able to purchase advertising space here and we'll include links to nano-reefs, reefcentral, and a few others that we decide are helpful to hobbyists.
In future versions, we hope to implement the ability to stream live video from your tank. This would require a IP based webcam and a few tweaks to your home router. This is pretty far out, so we figured it best to leave out of the initial version.
Now that I've laid out the plans, here's what I need from you guys
1. Help us name this app. Names actually mean a lot in the mobile app world.
2. Help us figure out a cost. I'm thinking somewhere in the $2.99 - $4.99 range. More or Less?
