CypherAir vs Erosion 蚀

CypherAir is a fully offline, open-source OpenPGP encryption tool built for iOS, iPadOS, macOS and VisionOS. It makes zero network connections. There is no telemetry, no tracking, and no possibility of data leakage. Two Encryption Profiles • Universal (Profile A) — Interoperable with GnuPG and all major PGP implementations. RFC 4880 compliant, employing Ed25519 and X25519 with SEIPDv1. • Advanced (Profile B) — Implements the latest OpenPGP standard, RFC 9580, with Ed448 and X448, authenticated encryption via AEAD (SEIPDv2), and Argon2id passphrase protection. Capabilities • Encrypt and decrypt text and files, processed as streams for efficiency • Create digital signatures — cleartext for messages, detached for files • Exchange public keys through QR codes using the system Camera, with no camera permission required • Manage multiple keys, each with its own encryption profile • Safeguard private keys in the Secure Enclave, unlocked only by Face ID or Touch ID Privacy Through Architecture • The sole system permission is the Face ID usage description • Private keys never leave the protection of Secure Enclave wrapping Open Source CypherAir is open source and available under the GNU General Public License v3.0 or later (GPL-3.0-or-later) or the Mozilla Public License 2.0 (MPL-2.0).

Erosion 是一款基于任务记录的专注工具。 应用采用“负向愿景”机制：通过呈现未完成任务所带来的结果变化，帮助用户更直观地理解时间与行动之间的关系。 在 Erosion 中，用户每天最多可以设置 3 个任务，并为每个任务分配专注时长。任务的完成或未完成，都会被记录并反馈到系统中。 应用的核心反馈方式为“日蚀状态”： - 当任务按计划完成时，日蚀程度减弱，秩序值提升 - 当任务未完成或被放弃时，日蚀程度加深，秩序值下降 这种可视化变化用于直观呈现任务执行情况，而不依赖传统的提醒或奖励机制。 主要功能包括： - 每日最多设置 3 个任务 - 支持专注时长记录 - 任务完成情况记录与展示 - 基于任务状态的日蚀变化反馈 - 简洁界面与低干扰设计 应用不提供复杂的激励或提醒功能，重点在于通过清晰的结果反馈，帮助用户专注于当前任务并理解执行情况。
