In case it is of use to others, here's a comparison chart of the software I used on iOS and what I'm now using on /e/.
Where I'm using the same application on both - Element, Signal, Tor Browser etc. - I have not bothered listing it.
I obtained as much as I could from the native /e/ app store, Apps, but I did have to resort to the Aurora Store for some things.
"Translation" table
| iOS application | /e/ application | Comments |
|---|---|---|
| Safari | Firefox | Browser. It makes me wish I'd used Firefox more on iOS |
| Canary Mail | k9 with OpenPGP | Email client, with PGP. (I tried Canary Mail for Android, but their support was lacking, so I gave up.) |
| TweetBot | Twidere | Twitter client |
| Tootle | Tusky | Mastodon client (although I'm seeing if Twidere will work for this too |
| I didn't have one | Transistor | Internet radio client |
| Native support | DAVx5 | xDAV client, for calender, contacts, and tasks synchronisation |
| Tasks | OpenTasks | Task manager (kept in sync via DAVx5) |
| InfiniTime | Gadgetbridge | PineTime client |
| WireGuard | WireGuard | WireGuard client but, unlike iOS, WireGuard for Android does not support on-demand activation. I'm using the native Android VPN settings to force WireGuard to be always-on, but I want to explore using Tasker for on-demand activation |
| Groundwire | Linphone | SIP client |
Bits where I am struggling.
Jellyfin. It does not work properly if not foregrounded. This includes when the screen is off, which is a pain when listening to things.
Petrol station apps (and possibly others): I've yet to work out why they appear provisioned to access the device's GPS but cannot seem to be able to do so. Which renders them useless.
