2. 2/5No Credit Tracking

   After using Base44 for a couple of months, I was actually - initially - impressed with how this app worked and the first app that I created, and I figured $36 for 12,000 credits was worth a try. However, I quickly realized there is NO WAY to track your credit usage (which concerned me immediately) and there was no documentation that explains how credits were charged. I even asked the app about how credits were charged, and IT told me OnSpace doesn’t use credits. I copy and pasted my plan, and it replied “my apologies, you’re right; we do use credits. I tried to go to support and the button didn’t even work; luckily the AI gave me the email address when I was asking about credit charges earlier. Anyway, I started working last night, MAYBE submitted around 30-50 prompts (definitely not more than 100) and MAYBE another 50 or so today before I got notice that I needed to purchase more credits! There’s no way I used anywhere close to 300 credits let alone 12,000 in one day! They must charge 60 credits per inquiry. I’m definitely cancelling.

3. 2/5Started ok,ended horrible

   At the start I made my first working app but I didn’t publish it. After a bit,I ran into a problem. So I was trying to make an app but it wouldn’t let me. I thought maybe I took up too much space so I deleted the other two apps I made. But then I found out what it really was! So basically,you have these coins. Anytime you make an app you us them up. Once you’ve used all of them,you have to get a subscription to make the apps! And if you’re wondering,no! I didn’t get the subscription. Developer note— If you want to make a successful app,don’t make people pay just to use the app. If you’re a developer,you read this,and you did this,then you’re just asking for bad reviews. PS-Igave this two stars because the apps I made worked

4. 5/5Unbelievable

   I gave 3 apps the same exact prompt, created by AI to be well interpreted. All 3 returned results, but only 1 returned a viable app. And that was onspace. Now it is creating a backend to finish the app while the other 2 sit and spin doing zilch. The other 2 are big players, OnSpace just whipped them. My only app for development is OnSpace, 10 stars of I could give them.

5. 2/5Customer service is non existent

   I downloaded this app to make something for my business. I have been over charged upon asking to fix an existing issue over and over wasting credits contacting support no answer and issues still there. For simple apps sure it’s ok not worth the monthly fee. If you have an issue customer support does not respond no matter how many times you email them. And the issues within the app doesn’t get fixed either.
