aSTRING Chaos
Read full descriptionHide full description
Some connections are one-on-one. Others tie a whole group together. aString is built around two kinds of connection โ Strings and Knots. A String is a conversation between two people. It can be anonymous, where you're just a name the system gave you, or open, where you show up as yourself. Either way, it's just you and one other person. A Knot is a space where a group comes together around something shared. Some are open to anyone, others you have to request to join. Some are anonymous, some aren't. Each Knot sets its own rules โ you just decide if it's somewhere you belong. Every person on aString is verified โ through a university or professional email. No guests, no throwaway accounts. Just real people from real institutions. One app. Two kinds of space. You choose how much of yourself to bring. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: ESC COP at none against aSTRING Chaos's 2. ESC COP also leads on ads (none vs shown) and iOS requirement (16.4 vs 18.2). On price, update cadence and device support there is nothing between them.
