It’s Great... Except

I love the app! I’ve been using for a while off and on. I recently decided to upgrade from a Basic to a Pro account. I went through the whole process and was even charged from Apple for the pro membership. It’s been 5 days and my app still says I have a basic membership (even though I’ve already paid for Pro).

Please figure out how to make sure peoples upgrades take effect immediately, or wait to charge their account until you can initiate the upgrade.

I think this app and creator Dmitry deserves A+++

I am new to this hobby transitioning from freshwater to saltwater aquarium. After close to two months of research I have made the decision to setup my tank. I came across a lot of app and saw the reviews of AquaticLog and decided to try them. In a few days after me downloading the app I received a email from the creator Dmitry and just that follow up email has shown how much you care for your customers let alone for all the hobbiest out there who use this app. I am very very new but from what I have read and see I think I am headed in the right direction while using this app I will be able to keep and maintain a good record of all that I will need to know about my aquarium. TEAM of AquaticLog please keep up the AWESOME WORK and look forward to becoming a PRO member soon with you guys. Thank you and Happy Reefing.. 👌👏👌👏

Great application, complete, and easy to use

This is a great application for documenting all of your activities with your reef. It’s easy to use and intuitive when navigating through the different areas. It graphs my all parameters so that I can see trends and there is room for notes in every entry. I’ve been able to record all of my maintenance efforts and set reminders (great feature). I am able to document what I’m dosing, how much, how often, for both manual and automatic doses. I’ve all my corals and inhabitants, dated when I’ve added them and can store pictures to record their progress. In addition to all of the great features, the app has been very stable, I’ve had zero issues.
If you are looking for a simple but yet complete app to manage and record your reef, this is the application for the job.
